[PHP];;;;;;;;;;;;;;;;;;;; About php.ini ;;;;;;;;;;;;;;;;;;;;; PHP's initialization file, generally called php.ini, is responsible for; configuring many of the aspects of PHP's behavior.; PHP attempts to find and load this configuration from a number of locations.; The following is a summary of its search order:; 1. SAPI module specific location.; 2. The PHPRC environment variable. (As of PHP 5.2.0); 3. A number of predefined registry keys on Windows (As of PHP 5.2.0); 4. Current working directory (except CLI); 5. The web server's directory (for SAPI modules), or directory of PHP; (otherwise in Windows); 6. The directory from the --with-config-file-path compile time option, or the; Windows directory (usually C:\windows); See the PHP docs for more specific information.; http://php.net/configuration.file; The syntax of the file is extremely simple. Whitespace and lines; beginning with a semicolon are silently ignored (as you probably guessed).; Section headers (e.g. [Foo]) are also silently ignored, even though; they might mean something in the future.; Directives following the section heading [PATH=/www/mysite] only; apply to PHP files in the /www/mysite directory. Directives; following the section heading [HOST=www.example.com] only apply to; PHP files served from www.example.com. Directives set in these; special sections cannot be overridden by user-defined INI files or; at runtime. Currently, [PATH=] and [HOST=] sections only work under; CGI/FastCGI.; http://php.net/ini.sections; Directives are specified using the following syntax:; directive = value; Directive names are *case sensitive* - foo=bar is different from FOO=bar.; Directives are variables used to configure PHP or PHP extensions.; There is no name validation. If PHP can't find an expected; directive because it is not set or is mistyped, a default value will be used.; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one; of the INI constants (On, Off, True, False, Yes, No and None) or an expression; (e.g. E_ALL & ~E_NOTICE), a quoted string ("bar"), or a reference to a; previously set variable or directive (e.g. ${foo}); Expressions in the INI file are limited to bitwise operators and parentheses:; | bitwise OR; ^ bitwise XOR; & bitwise AND; ~ bitwise NOT; ! boolean NOT; Boolean flags can be turned on using the values 1, On, True or Yes.; They can be turned off using the values 0, Off, False or No.; An empty string can be denoted by simply not writing anything after the equal; sign, or by using the None keyword:; foo = ; sets foo to an empty string; foo = None ; sets foo to an empty string; foo = "None" ; sets foo to the string 'None'; If you use constants in your value, and these constants belong to a; dynamically loaded extension (either a PHP extension or a Zend extension),; you may only use these constants *after* the line that loads the extension.;;;;;;;;;;;;;;;;;;;; About this file ;;;;;;;;;;;;;;;;;;;;; PHP comes packaged with two INI files. One that is recommended to be used; in production environments and one that is recommended to be used in; development environments.; php.ini-production contains settings which hold security, performance and; best practices at its core. But please be aware, these settings may break; compatibility with older or less security conscience applications. We; recommending using the production ini in production and testing environments.; php.ini-development is very similar to its production variant, except it is; much more verbose when it comes to errors. We recommend using the; development version only in development environments, as errors shown to; application users can inadvertently leak otherwise secure information.; This is the php.ini-production INI file.;;;;;;;;;;;;;;;;;;;; Quick Reference ;;;;;;;;;;;;;;;;;;;;; The following are all the settings which are different in either the production; or development versions of the INIs with respect to PHP's default behavior.; Please see the actual settings later in the document for more details as to why; we recommend these changes in PHP's behavior.; display_errors; Default Value: On; Development Value: On; Production Value: Off; display_startup_errors; Default Value: Off; Development Value: On; Production Value: Off; error_reporting; Default Value: E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED; Development Value: E_ALL; Production Value: E_ALL & ~E_DEPRECATED & ~E_STRICT; log_errors; Default Value: Off; Development Value: On; Production Value: On; max_input_time; Default Value: -1 (Unlimited); Development Value: 60 (60 seconds); Production Value: 60 (60 seconds); output_buffering; Default Value: Off; Development Value: 4096; Production Value: 4096; register_argc_argv; Default Value: On; Development Value: Off; Production Value: Off; request_order; Default Value: None; Development Value: "GP"; Production Value: "GP"; session.gc_divisor; Default Value: 100; Development Value: 1000; Production Value: 1000; session.sid_bits_per_character; Default Value: 4; Development Value: 5; Production Value: 5; short_open_tag; Default Value: On; Development Value: Off; Production Value: Off; variables_order; Default Value: "EGPCS"; Development Value: "GPCS"; Production Value: "GPCS";;;;;;;;;;;;;;;;;;;;; php.ini Options ;;;;;;;;;;;;;;;;;;;;;; Name for user-defined php.ini (.htaccess) files. Default is ".user.ini";user_ini.filename = ".user.ini"; To disable this feature set this option to an empty value;user_ini.filename =; TTL for user-defined php.ini files (time-to-live) in seconds. Default is 300 seconds (5 minutes);user_ini.cache_ttl = 300;;;;;;;;;;;;;;;;;;;;; Language Options ;;;;;;;;;;;;;;;;;;;;;; Enable the PHP scripting language engine under Apache.; http://php.net/engineengine = On; This directive determines whether or not PHP will recognize code between; <? and ?> tags as PHP source which should be processed as such. It is; generally recommended that <?php and ?> should be used and that this feature; should be disabled, as enabling it may result in issues when generating XML; documents, however this remains supported for backward compatibility reasons.; Note that this directive does not control the <?= shorthand tag, which can be; used regardless of this directive.; Default Value: On; Development Value: Off; Production Value: Off; http://php.net/short-open-tagshort_open_tag = Off; The number of significant digits displayed in floating point numbers.; http://php.net/precisionprecision = 14; Output buffering is a mechanism for controlling how much output data; (excluding headers and cookies) PHP should keep internally before pushing that; data to the client. If your application's output exceeds this setting, PHP; will send that data in chunks of roughly the size you specify.; Turning on this setting and managing its maximum buffer size can yield some; interesting side-effects depending on your application and web server.; You may be able to send headers and cookies after you've already sent output; through print or echo. You also may see performance benefits if your server is; emitting less packets due to buffered output versus PHP streaming the output; as it gets it. On production servers, 4096 bytes is a good setting for performance; reasons.; Note: Output buffering can also be controlled via Output Buffering Control; functions.; Possible Values:; On = Enabled and buffer is unlimited. (Use with caution); Off = Disabled; Integer = Enables the buffer and sets its maximum size in bytes.; Note: This directive is hardcoded to Off for the CLI SAPI; Default Value: Off; Development Value: 4096; Production Value: 4096; http://php.net/output-bufferingoutput_buffering = 4096; You can redirect all of the output of your scripts to a function. For; example, if you set output_handler to "mb_output_handler", character; encoding will be transparently converted to the specified encoding.; Setting any output handler automatically turns on output buffering.; Note: People who wrote portable scripts should not depend on this ini; directive. Instead, explicitly set the output handler using ob_start().; Using this ini directive may cause problems unless you know what script; is doing.; Note: You cannot use both "mb_output_handler" with "ob_iconv_handler"; and you cannot use both "ob_gzhandler" and "zlib.output_compression".; Note: output_handler must be empty if this is set 'On' !!!!; Instead you must use zlib.output_handler.; http://php.net/output-handler;output_handler =; URL rewriter function rewrites URL on the fly by using; output buffer. You can set target tags by this configuration.; "form" tag is special tag. It will add hidden input tag to pass values.; Refer to session.trans_sid_tags for usage.; Default Value: "form="; Development Value: "form="; Production Value: "form=";url_rewriter.tags; URL rewriter will not rewrite absolute URL nor form by default. To enable; absolute URL rewrite, allowed hosts must be defined at RUNTIME.; Refer to session.trans_sid_hosts for more details.; Default Value: ""; Development Value: ""; Production Value: "";url_rewriter.hosts; Transparent output compression using the zlib library; Valid values for this option are 'off', 'on', or a specific buffer size; to be used for compression (default is 4KB); Note: Resulting chunk size may vary due to nature of compression. PHP; outputs chunks that are few hundreds bytes each as a result of; compression. If you prefer a larger chunk size for better; performance, enable output_buffering in addition.; Note: You need to use zlib.output_handler instead of the standard; output_handler, or otherwise the output will be corrupted.; http://php.net/zlib.output-compressionzlib.output_compression = Off; http://php.net/zlib.output-compression-level;zlib.output_compression_level = -1; You cannot specify additional output handlers if zlib.output_compression; is activated here. This setting does the same as output_handler but in; a different order.; http://php.net/zlib.output-handler;zlib.output_handler =; Implicit flush tells PHP to tell the output layer to flush itself; automatically after every output block. This is equivalent to calling the; PHP function flush() after each and every call to print() or echo() and each; and every HTML block. Turning this option on has serious performance; implications and is generally recommended for debugging purposes only.; http://php.net/implicit-flush; Note: This directive is hardcoded to On for the CLI SAPIimplicit_flush = Off; The unserialize callback function will be called (with the undefined class'; name as parameter), if the unserializer finds an undefined class; which should be instantiated. A warning appears if the specified function is; not defined, or if the function doesn't include/implement the missing class.; So only set this entry, if you really want to implement such a; callback-function.unserialize_callback_func =; The unserialize_max_depth specifies the default depth limit for unserialized; structures. Setting the depth limit too high may result in stack overflows; during unserialization. The unserialize_max_depth ini setting can be; overridden by the max_depth option on individual unserialize() calls.; A value of 0 disables the depth limit.;unserialize_max_depth = 4096; When floats & doubles are serialized, store serialize_precision significant; digits after the floating point. The default value ensures that when floats; are decoded with unserialize, the data will remain the same.; The value is also used for json_encode when encoding double values.; If -1 is used, then dtoa mode 0 is used which automatically select the best; precision.serialize_precision = -1; open_basedir, if set, limits all file operations to the defined directory; and below. This directive makes most sense if used in a per-directory; or per-virtualhost web server configuration file.; Note: disables the realpath cache; http://php.net/open-basedir;open_basedir =; This directive allows you to disable certain functions.; It receives a comma-delimited list of function names.; http://php.net/disable-functionsdisable_functions =; This directive allows you to disable certain classes.; It receives a comma-delimited list of class names.; http://php.net/disable-classesdisable_classes =; Colors for Syntax Highlighting mode. Anything that's acceptable in; <span style="color: ???????"> would work.; http://php.net/syntax-highlighting;highlight.string = #DD0000;highlight.comment = #FF9900;highlight.keyword = #007700;highlight.default = #0000BB;highlight.html = #000000; If enabled, the request will be allowed to complete even if the user aborts; the request. Consider enabling it if executing long requests, which may end up; being interrupted by the user or a browser timing out. PHP's default behavior; is to disable this feature.; http://php.net/ignore-user-abort;ignore_user_abort = On; Determines the size of the realpath cache to be used by PHP. This value should; be increased on systems where PHP opens many files to reflect the quantity of; the file operations performed.; Note: if open_basedir is set, the cache is disabled; http://php.net/realpath-cache-size;realpath_cache_size = 4096k; Duration of time, in seconds for which to cache realpath information for a given; file or directory. For systems with rarely changing files, consider increasing this; value.; http://php.net/realpath-cache-ttl;realpath_cache_ttl = 120; Enables or disables the circular reference collector.; http://php.net/zend.enable-gczend.enable_gc = On; If enabled, scripts may be written in encodings that are incompatible with; the scanner. CP936, Big5, CP949 and Shift_JIS are the examples of such; encodings. To use this feature, mbstring extension must be enabled.; Default: Off;zend.multibyte = Off; Allows to set the default encoding for the scripts. This value will be used; unless "declare(encoding=...)" directive appears at the top of the script.; Only affects if zend.multibyte is set.; Default: "";zend.script_encoding =; Allows to include or exclude arguments from stack traces generated for exceptions; Default: Off; In production, it is recommended to turn this setting on to prohibit the output; of sensitive information in stack traceszend.exception_ignore_args = On;;;;;;;;;;;;;;;;;; Miscellaneous ;;;;;;;;;;;;;;;;;;; Decides whether PHP may expose the fact that it is installed on the server; (e.g. by adding its signature to the Web server header). It is no security; threat in any way, but it makes it possible to determine whether you use PHP; on your server or not.; http://php.net/expose-phpexpose_php = On;;;;;;;;;;;;;;;;;;;; Resource Limits ;;;;;;;;;;;;;;;;;;;;; Maximum execution time of each script, in seconds; http://php.net/max-execution-time; Note: This directive is hardcoded to 0 for the CLI SAPI;max_execution_time = 30max_execution_time = 600; Maximum amount of time each script may spend parsing request data. It's a good; idea to limit this time on productions servers in order to eliminate unexpectedly; long running scripts.; Note: This directive is hardcoded to -1 for the CLI SAPI; Default Value: -1 (Unlimited); Development Value: 60 (60 seconds); Production Value: 60 (60 seconds); http://php.net/max-input-timemax_input_time = 60; Maximum input variable nesting level; http://php.net/max-input-nesting-level;max_input_nesting_level = 64; How many GET/POST/COOKIE input variables may be accepted;max_input_vars = 1000; Maximum amount of memory a script may consume; http://php.net/memory-limit;memory_limit = 128Mmemory_limit = 5120M;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; Error handling and logging ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; This directive informs PHP of which errors, warnings and notices you would like; it to take action for. The recommended way of setting values for this; directive is through the use of the error level constants and bitwise; operators. The error level constants are below here for convenience as well as; some common settings and their meanings.; By default, PHP is set to take action on all errors, notices and warnings EXCEPT; those related to E_NOTICE and E_STRICT, which together cover best practices and; recommended coding standards in PHP. For performance reasons, this is the; recommend error reporting setting. Your production server shouldn't be wasting; resources complaining about best practices and coding standards. That's what; development servers and development settings are for.; Note: The php.ini-development file has this setting as E_ALL. This; means it pretty much reports everything which is exactly what you want during; development and early testing.;; Error Level Constants:; E_ALL - All errors and warnings (includes E_STRICT as of PHP 5.4.0); E_ERROR - fatal run-time errors; E_RECOVERABLE_ERROR - almost fatal run-time errors; E_WARNING - run-time warnings (non-fatal errors); E_PARSE - compile-time parse errors; E_NOTICE - run-time notices (these are warnings which often result; from a bug in your code, but it's possible that it was; intentional (e.g., using an uninitialized variable and; relying on the fact it is automatically initialized to an; empty string); E_STRICT - run-time notices, enable to have PHP suggest changes; to your code which will ensure the best interoperability; and forward compatibility of your code; E_CORE_ERROR - fatal errors that occur during PHP's initial startup; E_CORE_WARNING - warnings (non-fatal errors) that occur during PHP's; initial startup; E_COMPILE_ERROR - fatal compile-time errors; E_COMPILE_WARNING - compile-time warnings (non-fatal errors); E_USER_ERROR - user-generated error message; E_USER_WARNING - user-generated warning message; E_USER_NOTICE - user-generated notice message; E_DEPRECATED - warn about code that will not work in future versions; of PHP; E_USER_DEPRECATED - user-generated deprecation warnings;; Common Values:; E_ALL (Show all errors, warnings and notices including coding standards.); E_ALL & ~E_NOTICE (Show all errors, except for notices); E_ALL & ~E_NOTICE & ~E_STRICT (Show all errors, except for notices and coding standards warnings.); E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR (Show only errors); Default Value: E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED; Development Value: E_ALL; Production Value: E_ALL & ~E_DEPRECATED & ~E_STRICT; http://php.net/error-reportingerror_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT; This directive controls whether or not and where PHP will output errors,; notices and warnings too. Error output is very useful during development, but; it could be very dangerous in production environments. Depending on the code; which is triggering the error, sensitive information could potentially leak; out of your application such as database usernames and passwords or worse.; For production environments, we recommend logging errors rather than; sending them to STDOUT.; Possible Values:; Off = Do not display any errors; stderr = Display errors to STDERR (affects only CGI/CLI binaries!); On or stdout = Display errors to STDOUT; Default Value: On; Development Value: On; Production Value: Off; http://php.net/display-errorsdisplay_errors = Off; The display of errors which occur during PHP's startup sequence are handled; separately from display_errors. PHP's default behavior is to suppress those; errors from clients. Turning the display of startup errors on can be useful in; debugging configuration problems. We strongly recommend you; set this to 'off' for production servers.; Default Value: Off; Development Value: On; Production Value: Off; http://php.net/display-startup-errorsdisplay_startup_errors = Off; Besides displaying errors, PHP can also log errors to locations such as a; server-specific log, STDERR, or a location specified by the error_log; directive found below. While errors should not be displayed on productions; servers they should still be monitored and logging is a great way to do that.; Default Value: Off; Development Value: On; Production Value: On; http://php.net/log-errorslog_errors = On; Set maximum length of log_errors. In error_log information about the source is; added. The default is 1024 and 0 allows to not apply any maximum length at all.; http://php.net/log-errors-max-lenlog_errors_max_len = 1024; Do not log repeated messages. Repeated errors must occur in same file on same; line unless ignore_repeated_source is set true.; http://php.net/ignore-repeated-errorsignore_repeated_errors = Off; Ignore source of message when ignoring repeated messages. When this setting; is On you will not log errors with repeated messages from different files or; source lines.; http://php.net/ignore-repeated-sourceignore_repeated_source = Off; If this parameter is set to Off, then memory leaks will not be shown (on; stdout or in the log). This is only effective in a debug compile, and if; error reporting includes E_WARNING in the allowed list; http://php.net/report-memleaksreport_memleaks = On; This setting is on by default.;report_zend_debug = 0; Store the last error/warning message in $php_errormsg (boolean). Setting this value; to On can assist in debugging and is appropriate for development servers. It should; however be disabled on production servers.; This directive is DEPRECATED.; Default Value: Off; Development Value: Off; Production Value: Off; http://php.net/track-errors;track_errors = Off; Turn off normal error reporting and emit XML-RPC error XML; http://php.net/xmlrpc-errors;xmlrpc_errors = 0; An XML-RPC faultCode;xmlrpc_error_number = 0; When PHP displays or logs an error, it has the capability of formatting the; error message as HTML for easier reading. This directive controls whether; the error message is formatted as HTML or not.; Note: This directive is hardcoded to Off for the CLI SAPI; http://php.net/html-errors;html_errors = On; If html_errors is set to On *and* docref_root is not empty, then PHP; produces clickable error messages that direct to a page describing the error; or function causing the error in detail.; You can download a copy of the PHP manual from http://php.net/docs; and change docref_root to the base URL of your local copy including the; leading '/'. You must also specify the file extension being used including; the dot. PHP's default behavior is to leave these settings empty, in which; case no links to documentation are generated.; Note: Never use this feature for production boxes.; http://php.net/docref-root; Examples;docref_root = "/phpmanual/"; http://php.net/docref-ext;docref_ext = .html; String to output before an error message. PHP's default behavior is to leave; this setting blank.; http://php.net/error-prepend-string; Example:;error_prepend_string = "<span style='color: #ff0000'>"; String to output after an error message. PHP's default behavior is to leave; this setting blank.; http://php.net/error-append-string; Example:;error_append_string = "</span>"; Log errors to specified file. PHP's default behavior is to leave this value; empty.; http://php.net/error-log; Example:error_log = php_errors.log; Log errors to syslog (Event Log on Windows).;error_log = syslog; The syslog ident is a string which is prepended to every message logged; to syslog. Only used when error_log is set to syslog.;syslog.ident = php; The syslog facility is used to specify what type of program is logging; the message. Only used when error_log is set to syslog.;syslog.facility = user; Set this to disable filtering control characters (the default).; Some loggers only accept NVT-ASCII, others accept anything that's not; control characters. If your logger accepts everything, then no filtering; is needed at all.; Allowed values are:; ascii (all printable ASCII characters and NL); no-ctrl (all characters except control characters); all (all characters); raw (like "all", but messages are not split at newlines); http://php.net/syslog.filter;syslog.filter = ascii;windows.show_crt_warning; Default value: 0; Development value: 0; Production value: 0;;;;;;;;;;;;;;;;;; Data Handling ;;;;;;;;;;;;;;;;;;; The separator used in PHP generated URLs to separate arguments.; PHP's default setting is "&".; http://php.net/arg-separator.output; Example:;arg_separator.output = "&"; List of separator(s) used by PHP to parse input URLs into variables.; PHP's default setting is "&".; NOTE: Every character in this directive is considered as separator!; http://php.net/arg-separator.input; Example:;arg_separator.input = ";&"; This directive determines which super global arrays are registered when PHP; starts up. G,P,C,E & S are abbreviations for the following respective super; globals: GET, POST, COOKIE, ENV and SERVER. There is a performance penalty; paid for the registration of these arrays and because ENV is not as commonly; used as the others, ENV is not recommended on productions servers. You; can still get access to the environment variables through getenv() should you; need to.; Default Value: "EGPCS"; Development Value: "GPCS"; Production Value: "GPCS";; http://php.net/variables-ordervariables_order = "GPCS"; This directive determines which super global data (G,P & C) should be; registered into the super global array REQUEST. If so, it also determines; the order in which that data is registered. The values for this directive; are specified in the same manner as the variables_order directive,; EXCEPT one. Leaving this value empty will cause PHP to use the value set; in the variables_order directive. It does not mean it will leave the super; globals array REQUEST empty.; Default Value: None; Development Value: "GP"; Production Value: "GP"; http://php.net/request-orderrequest_order = "GP"; This directive determines whether PHP registers $argv & $argc each time it; runs. $argv contains an array of all the arguments passed to PHP when a script; is invoked. $argc contains an integer representing the number of arguments; that were passed when the script was invoked. These arrays are extremely; useful when running scripts from the command line. When this directive is; enabled, registering these variables consumes CPU cycles and memory each time; a script is executed. For performance reasons, this feature should be disabled; on production servers.; Note: This directive is hardcoded to On for the CLI SAPI; Default Value: On; Development Value: Off; Production Value: Off; http://php.net/register-argc-argvregister_argc_argv = Off; When enabled, the ENV, REQUEST and SERVER variables are created when they're; first used (Just In Time) instead of when the script starts. If these; variables are not used within a script, having this directive on will result; in a performance gain. The PHP directive register_argc_argv must be disabled; for this directive to have any effect.; http://php.net/auto-globals-jitauto_globals_jit = On; Whether PHP will read the POST data.; This option is enabled by default.; Most likely, you won't want to disable this option globally. It causes $_POST; and $_FILES to always be empty; the only way you will be able to read the; POST data will be through the php://input stream wrapper. This can be useful; to proxy requests or to process the POST data in a memory efficient fashion.; http://php.net/enable-post-data-reading;enable_post_data_reading = Off; Maximum size of POST data that PHP will accept.; Its value may be 0 to disable the limit. It is ignored if POST data reading; is disabled through enable_post_data_reading.; http://php.net/post-max-sizepost_max_size = 16M; Automatically add files before PHP document.; http://php.net/auto-prepend-fileauto_prepend_file =; Automatically add files after PHP document.; http://php.net/auto-append-fileauto_append_file =; By default, PHP will output a media type using the Content-Type header. To; disable this, simply set it to be empty.;; PHP's built-in default media type is set to text/html.; http://php.net/default-mimetypedefault_mimetype = "text/html"; PHP's default character set is set to UTF-8.; http://php.net/default-charsetdefault_charset = "UTF-8"; PHP internal character encoding is set to empty.; If empty, default_charset is used.; http://php.net/internal-encoding;internal_encoding =; PHP input character encoding is set to empty.; If empty, default_charset is used.; http://php.net/input-encoding;input_encoding =; PHP output character encoding is set to empty.; If empty, default_charset is used.; See also output_buffer.; http://php.net/output-encoding;output_encoding =;;;;;;;;;;;;;;;;;;;;;;;;;; Paths and Directories ;;;;;;;;;;;;;;;;;;;;;;;;;;; UNIX: "/path1:/path2";include_path = ".:/php/includes";; Windows: "\path1;\path2";include_path = ".;c:\php\includes";; PHP's default setting for include_path is ".;/path/to/php/pear"; http://php.net/include-path; The root of the PHP pages, used only if nonempty.; if PHP was not compiled with FORCE_REDIRECT, you SHOULD set doc_root; if you are running php as a CGI under any web server (other than IIS); see documentation for security issues. The alternate is to use the; cgi.force_redirect configuration below; http://php.net/doc-rootdoc_root =; The directory under which PHP opens the script using /~username used only; if nonempty.; http://php.net/user-diruser_dir =; Directory in which the loadable extensions (modules) reside.; http://php.net/extension-dir;extension_dir = "./"; On windows:;extension_dir = "ext"; Directory where the temporary files should be placed.; Defaults to the system default (see sys_get_temp_dir);sys_temp_dir = "/tmp"; Whether or not to enable the dl() function. The dl() function does NOT work; properly in multithreaded servers, such as IIS or Zeus, and is automatically; disabled on them.; http://php.net/enable-dlenable_dl = Off; cgi.force_redirect is necessary to provide security running PHP as a CGI under; most web servers. Left undefined, PHP turns this on by default. You can; turn it off here AT YOUR OWN RISK; **You CAN safely turn this off for IIS, in fact, you MUST.**; http://php.net/cgi.force-redirect;cgi.force_redirect = 1; if cgi.nph is enabled it will force cgi to always sent Status: 200 with; every request. PHP's default behavior is to disable this feature.;cgi.nph = 1; if cgi.force_redirect is turned on, and you are not running under Apache or Netscape; (iPlanet) web servers, you MAY need to set an environment variable name that PHP; will look for to know it is OK to continue execution. Setting this variable MAY; cause security issues, KNOW WHAT YOU ARE DOING FIRST.; http://php.net/cgi.redirect-status-env;cgi.redirect_status_env =; cgi.fix_pathinfo provides *real* PATH_INFO/PATH_TRANSLATED support for CGI. PHP's; previous behaviour was to set PATH_TRANSLATED to SCRIPT_FILENAME, and to not grok; what PATH_INFO is. For more information on PATH_INFO, see the cgi specs. Setting; this to 1 will cause PHP CGI to fix its paths to conform to the spec. A setting; of zero causes PHP to behave as before. Default is 1. You should fix your scripts; to use SCRIPT_FILENAME rather than PATH_TRANSLATED.; http://php.net/cgi.fix-pathinfocgi.fix_pathinfo=1; if cgi.discard_path is enabled, the PHP CGI binary can safely be placed outside; of the web tree and people will not be able to circumvent .htaccess security.;cgi.discard_path=1; FastCGI under IIS supports the ability to impersonate; security tokens of the calling client. This allows IIS to define the; security context that the request runs under. mod_fastcgi under Apache; does not currently support this feature (03/17/2002); Set to 1 if running under IIS. Default is zero.; http://php.net/fastcgi.impersonate;fastcgi.impersonate = 1; Disable logging through FastCGI connection. PHP's default behavior is to enable; this feature.;fastcgi.logging = 0; cgi.rfc2616_headers configuration option tells PHP what type of headers to; use when sending HTTP response code. If set to 0, PHP sends Status: header that; is supported by Apache.
