; About php.ini   ;
;;;;;;;;;;;;;;;;;;;
; PHP’s initialization file, generally called php.ini, is responsible
for
; configuring many of the aspects of PHP’s behavior.
; php的初始化文件,通常叫做php.ini,负责配置php很多层面的行为

; 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.
;
; php在多个位置尝试加载这个配置文件
; 下面是php加载这个文件时的搜索顺序:
; 1. SAPI模块特定的位置
; 2. PHPRC环境变量(PHP5.2.0开始)
; 3. windows下一系列的预定义的注册表键(PHP5.2.0开始)
; 4. 当前工作目录(除了CLI)
; 5. 网络服务器目录(针对SAPI模块)或者PHP目录(otherwise in Windows)
; 6.
编译时–with-config-file-path选项所指的目录或者windows目录(C:windows
or C:winnt)
; 查看PHP文档获得更多详细信息

; 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.
; 这个文件的语法是十分简单的,空白和以“;”开头的行都是自动忽略的,章节标题(如[Foo])也是自动忽略的,即使他们可能具有一些实际意义

; 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.
;
; 标题[PATH=/www/mysite]后的指令只应用于/www/mysite目录下的PHP文件,标题[HOST=www.example.com]后的指令只应用于;在

; www.example.com上的PHP文件,这些特殊的节下面设置的指令不可以被用户自定义的INI文件覆写,或在运行时被重写。目前[PATH=]
和 

; [HOST=]只在CGI/FastCGI下工作

; 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.
; 指令规定使用下面的语法:
; directive = value
; 指令的名字是大小写敏感的,比如foo=bar 和 FOO=bar 是不一样的
; 指令是用于配置PHP或PHP扩展的变量。这些名字是不会被验证的,如果PHP因为期望的指令找不到或是因为期望的指令被写错了,它会使用默认值

; 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})
; 这里的值可以是字符串,数字,PHP常量(如E_ALL or
M_PI),INI文件定义的一个常量(On, Off, True, False, Yes, No 和
None),或者是一个表

; 达式(如E_ALL &
~E_NOTICE),引用字符串,或指向先前定义的变量或指令的引用

; Expressions in the INI file are limited to bitwise operators and
parentheses:
; 这个INI文件中的表达式仅仅可以使用位运算和括号
; |  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.
; 布尔标识可以用值1,On,True或者Yes打开,并且可以用0,Off,False或No关闭

; An empty string can be denoted by simply not writing anything after
the equal
; sign, or by using the None keyword:
; 一个空字符串可以用在等号后面表示不赋值或者使用“None”这个关键字来表示

;  foo =         ; sets foo to an empty string
;  foo = None    ; sets foo to an empty string
;  foo = “None”  ; sets foo to the string ‘None’ 【这个不是空字符串】

; 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.
; 如果你使用常量赋值,并且这些常量时属于动态加载的扩展的(无论是PHP扩展还是Zend扩展),那么你仅仅可以在加载这个扩展的行之后使用这些常量。

; 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包含两个INI文件,其中一个建议用在正式上线的环境中,另一个建议用在开发环境中

; php.ini-production contains settings which hold security, performance
and

break
; compatibility with older or less security conscience applications.
We

; php.ini-development is very similar to its production variant, except

; This directive determines whether or not PHP will recognize code

; 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.
;输出缓存是一个控制PHP在向客户端输出数据(除了头文件和cookies)时,应该在内部缓存多少数据的一个机制。如果你的应用输出超出这个设置,

;PHP会将那些数据大致按照你设置的大小分块输出。打开这个设置和管理它的最大缓冲区大小可能产生一些有趣的副作用,这取决于您的应用程序和

;web服务器。在你通过print和echo输出后你仍可以发送头部和cookies。如果因为buffered
output versus PHP streaming the output as it gets it

;你的服务器发送更少的数据包,你会看到性能优势。在生产服务器上,对于性能来说4096
bytes(字节)是一个好的配置

; 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

; You can redirect all of the output of your scripts to a function.

; Setting any output handler automatically turns on output buffering.
;你可以将你所有的脚本输出重定向到一个函数。例如,如果你设置output_handler为“mb_output_handler”,字符编码会被透明的转化为指定编

;码。设置任何输出处理程序会自动打开输出缓存。

; 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.
;注意:编写便携式脚本的人不应该依赖于这个ini指令,取而代之的是,使用ob-start()明确的设置输出处理程序。除非你知道脚本在做什么,否则将有
