; About php.ini ; //关于php;;;;;;;;;;;;;;;;;;;; PHP's initialization file, generally called php.ini, is responsible for; configuring many of the aspects of PHP's behavior. //这个是php初始化文件，通常称为php.ini，负责各个方面php行为的配置。; 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 (C:\windows or C:\winnt); 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's; much more verbose when it comes to errors. We recommending using the; development version only in development environments as errors shown to; application users can inadvertently leak otherwise secure information.; This is 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; html_errors; Default Value: On; Development Value: On; Production value: On; 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; 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.

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-pathinfo;cgi.fix_pathinfo=1; FastCGI under IIS (on WINNT based OS) 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 it's set 0 PHP sends Status: header that; is supported by Apache.
