php配置文件解析

PHP]

;;;;;;;;;;;
; WARNING ;
;;;;;;;;;;;
; This is the default settings file for new PHPinstallations.
; By default, PHP installs itself with a configuration suitablefor
; development purposes, and *NOT* for production purposes.
; For several security-oriented considerations that should betaken
; before going online with your site, please consultphp.ini-recommended
; and http://php.net/manual/en/security.php.


;;;;;;;;;;;;;;;;;;;
; About php.ini ;
;;;;;;;;;;;;;;;;;;;
; This file controls many aspects of PHP'sbehavior. In order for PHP to
; read it, it must be named 'php.ini'. PHP looksfor it in the current
; working directory, in the path designated by the environmentvariable
; PHPRC, and in the path that was defined in compile time (in thatorder).
; Under Windows, the compile-time path is the Windowsdirectory. The
; path in which the php.ini file is looked for can be overriddenusing
; the -c argument in command line mode.
;
; The syntax of the file is extremely simple.Whitespace and Lines
; beginning with a semicolon are silently ignored (as you probablyguessed).
; Section headers (e.g. [Foo]) are also silently ignored, eventhough
; they might mean something in the future.
;
; Directives are specified using the following syntax:
; directive = value
; Directive names are *case sensitive* - foo=bar is different fromFOO=bar.
;
; The value can be a string, a number, a PHP constant (e.g. E_ALLor M_PI), one
; of the INI constants (On, Off, True, False, Yes, No and None) oran expression
; (e.g. E_ALL & ~E_NOTICE), or a quoted string("foo").
;在ini文件本身使用的逻辑值使用的运算符
; Expressions in the INI file are limited to bitwise operators andparentheses:
;|bitwise OR
;&bitwise AND
;~bitwise NOT
;!boolean NOT
;
; Boolean flags can be turned on using the values 1, On, True orYes.
; They can be turned off using the values 0, Off, False orNo.
;
; An empty string can be denoted by simply not writing anythingafter the equal
; sign, or by using the None keyword:
;
; foo=; sets foo to an empty string
; foo =none ; setsfoo to an empty string
; foo = "none" ; sets foo tothe string 'none'
;
; If you use constants in your value, and these constants belong toa
; dynamically loaded extension (either a PHP extension or a Zendextension),
; you may only use these constants *after* the line that loads theextension.
;
;
;;;;;;;;;;;;;;;;;;;
; About this file ;
;;;;;;;;;;;;;;;;;;;
; All the values in the php.ini-dist file correspond to thebuiltin
; defaults (that is, if no php.ini is used, or if you delete theselines,
; the builtin defaults will be identical).

; Language Options ;
;;;;;;;;;;;;;;;;;;;;

; Enable the PHP scripting language engine under Apache.

; Allow the <? tag. Otherwise,only <?php and<script> tags are recognized.
; NOTE: Using short tags should be avoided when developingapplications or
; libraries that are meant for redistribution, or deployment onPHP
; servers which are not under your control, because short tags maynot
; be supported on the target server. For portable, redistributablecode,
; be sure not to use short tags.

;是否允许短开放标记<?标明PHP脚本

; The number of significant digits displayed in floating pointnumbers.

y2k_compliance = On

; Output buffering allows you to send header lines (includingcookies) even
; after you send body content, at the price of slowing PHP's outputlayer a
; bit. You can enable output buffering duringruntime by calling the output
; buffering functions. You can also enable outputbuffering for all files by
; setting this directive to On. If you wish tolimit the size of the buffer
; to a certain size - you can use a maximum number of bytes insteadof 'On', as
; a value for this directive (e.g., output_buffering=4096).

;启动后使用输出缓冲，PHP在脚本完成后一次发送所有输出。;

;开启后在HTTP首部已经发送后，能再发送一个cookie
output_buffering = Off

; You can redirect all of the output of your scripts to afunction. For
; example, if you set output_handler to "mb_output_handler",character
; encoding will be transparently converted to the specifiedencoding.
; Setting any output handler automatically turns on outputbuffering.
; Note: People who wrote portable scripts should not depend on thisini
;directive. Instead, explicitly set the output handler usingob_start().
;Using this ini directive may cause problems unless you know whatscript
;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.

;在输出返回给请求用户前，所有输出传递给一个函数，

;比如压缩所有输出output_handler ="ob_gzhandler"
;output_handler =

; Transparent output compression using the zlib library
; Valid values for this option are 'off', 'on', or a specificbuffer 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 resultof
;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 thestandard
;output_handler, or otherwise the output will be corrupted.

;启用后输出返回给浏览器前先压缩，节省带宽和时间，使用一个特定的值表示压缩缓冲区大小
zlib.output_compression = Off
;zlib.output_compression_level = -1

; You cannot specify additional output handlers ifzlib.output_compression
; is activated here. This setting does the same as output_handlerbut in
; a different order.

;如果zlib不可用，使用指定的压缩库

;zlib.output_handler =

; Implicit flush tells PHP to tell the output layer to flushitself
; automatically after every output block. This isequivalent to calling the
; PHP function flush() after each and every call to print() orecho() and each
; and every HTML block. Turning this option onhas serious performance
; implications and is generally recommended for debugging purposesonly.

; Whether to enable the ability to force arguments to be passed byreference
; at function call time. This method isdeprecated and is likely to be
; unsupported in future versions of PHP/Zend. Theencouraged method of
; specifying which arguments should be passed by reference is inthe function
; declaration. You're encouraged to try and turnthis option Off and make
