LNMP是Linux+Nginx+MySQL+PHP的简称，是一套完整的PHP网站服务器架构环境。
所用Linux发行版为Ubuntu Gnome 15.04，所有需要的软件均使用Ubuntu自带apt源下载安装。
首先，更新Ubuntu源： sudo apt-get update然后，安装Nginx：
sudo apt-get install nginx 等待nginx安装完成后，打开浏览器，在地址栏输入localhost，检测nginx是否开启；若开启成功，则会显示欢迎使用Nginx的界面；若没有，则在终端下输入以下命令即可打开nginx：sudo /etc/init.d/nginx start
然后安装mysql：sudo apt-get install mysql-server-5.6 mysql-workbench mysql-client-5.6
安装过程中需要设置root用户的密码，选择自己容易记住的密码即可。
接下来安装php：sudo apt-get install php5.6 php5.6-fpm php5.6-mysql php5.6-apc
至此所有基本组件已安装完毕，可以根据需要继续安装其它可选组件等。
配置php:首先：
sudo vim /etc/nginx/sites-available/default在打开的文档中找到root，将其改为：
root /home/tevenfeng/coding/php/tjurobocup
此处路径为你的php页面文件的根目录路径，比如我这里就把所有php页面放在tjurobocup文件夹下。
同时在index一行中添加 index.php。然后找到以下代码块并按照下面的修改：
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
#include snippets/fastcgi-php.conf;
## With php5-cgi alone:
#fastcgi_pass 127.0.0.1:9000;
## With php5-fpm:
fastcgi_pass unix:/var/run/php5-fpm.sock;
include fastcgi_params;
}
然后保存。
接下来修改fastcgi_params文件： sudo vim /etc/nginx/fastcgi_params在该文件的末尾添加如下行：
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
保存退出。
然后修改php.ini文件： sudo vim /etc/php5/fpm/php.ini找到:;cgi.fix_pathinfo()=1 （大约在700行附近）
将其修改为cgi.fix_pathinfo()=0
找到doc_root = （大约在720行左右）
将其修改为doc_root = /home/tevenfeng/coding/php/tjurobocup （注意，这里的路径必须与前面修改default文件中root的路径一致）。
保存并退出。
然后重启nginx和php5-fpm： sudo /etc/init.d/nginx restart sudo /etc/init.d/php5-fpm restart然后在/home/tevenfeng/coding/php/tjurobocup文件夹下新建一个index.php文件，并输入相应的测试内容，打开浏览器输入localhost测试。
如果出现：ubuntu E: Package 'php5' has no installation candidate
Add the PPA
sudo add-apt-repository ppa:ondrej/php
Install your PHP Version
sudo apt-get updatesudo apt-get install php5.6
link: http://stackoverflow.com/questions/36788873/package-php5-have-no-installation-candidate-ubuntu-16-04
如果出现 502 bad gateway 检查你的 nginx 配置文件
location ~ \.php$ {
# include snippets/fastcgi-php.conf; # # # With php7.0-cgi alone: # fastcgi_pass 127.0.0.1:9000; # # With php7.0-fpm: # fastcgi_pass unix:/run/php/php7.0-fpm.sock; fastcgi_pass unix:/var/run/php/php5.6-fpm.sock; 这个文件是否路径对 include fastcgi_params; }
一个web服务器里使用不用的PHP版本，只用通过虚拟主机配置文件引用PHP版本的不同既可。

[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 (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 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 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; 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.hash_bits_per_character; Default Value: 4; Development Value: 5; Production Value: 5; short_open_tag; Default Value: On; Development Value: Off; Production Value: Off; track_errors; Default Value: Off; Development Value: On; Production Value: Off; url_rewriter.tags; Default Value: "a=href,area=href,frame=src,form=,fieldset="; Development Value: "a=href,area=href,frame=src,input=src,form=fakeentry"; Production Value: "a=href,area=href,frame=src,input=src,form=fakeentry"; 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 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; tags as PHP source which should be processed as such. It is; generally recommended that 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 tags.; http://php.net/asp-tagsasp_tags = 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 =; 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 =; 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.serialize_precision = 17; 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.; http://php.net/open-basedir;open_basedir =; This directive allows you to disable certain functions for security reasons.; It receives a comma-delimited list of function names.; http://php.net/disable-functionsdisable_functions = pcntl_alarm,pcntl_fork,pcntl_waitpid,pcntl_wait,pcntl_wifexited,pcntl_wifstopped,pcntl_wifsignaled,pcntl_wexitstatus,pcntl_wtermsig,pcntl_wstopsig,pcntl_signal,pcntl_signal_dispatch,pcntl_get_last_error,pcntl_strerror,pcntl_sigprocmask,pcntl_sigwaitinfo,pcntl_sigtimedwait,pcntl_exec,pcntl_getpriority,pcntl_setpriority,; This directive allows you to disable certain classes for security reasons.; 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; 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.; http://php.net/realpath-cache-size;realpath_cache_size = 16k; 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 =;;;;;;;;;;;;;;;;;; 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 = Off;;;;;;;;;;;;;;;;;;;; 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 SAPImax_execution_time = 30; 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 (128MB); http://php.net/memory-limitmemory_limit = 128M;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; 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 has only effect 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.; Default Value: Off; Development Value: On; Production Value: Off; http://php.net/track-errorstrack_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; Default Value: On; Development Value: On; Production value: On; http://php.net/html-errorshtml_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 = ""; 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 = ""; 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;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 affect.; 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.
