; 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.
; http://php.NET/configuration.file
; 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.
; 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.
; http://php.net/ini.sections
; 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

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.
; 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
; 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-production拥有对安全、性能和对核心的最佳实践的设置，但是请注意，这些设置可能在较老或具有较低安全性的应用上会失去兼容性，所

; 以我们推荐在正式产品和测试环境中都使用php.ini-production

; 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.
; php.ini-development与production十分相似，只是当错误发生时，它显示的越详细。我们建议仅仅在开发环境中使用它，因为展示给用户的错误信

; 息可能会不经意间泄露一些安全信息。

; This is php.ini-production INI file.

; 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.
; 这个指令决定是否PHP会将标签<?和?>之间的代码识别为PHP应该执行的源，通常建议使用<?php 和 ?>，而禁止掉这个特性，因为它可能导致在生

; 成XML文档时出现问题。然后为了向后兼容，它现在还是被支持的。注意，这个指令并不控制<?=这个速写标签，它能够在这个指令的限制之外使用

; 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
; Default Value: Off

; Off = 关闭
; Integer = 启动缓存并设置它的最大缓冲字节数
output_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.
;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

; 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.
;注意：结果由于压缩的块大小可能会有所不同。PHP输出压缩后的几百字节大小的块，如果为了更好的性能你想要更大的块大小，你可以另外使用

;output_buffering
; Note: You need to use zlib.output_handler instead of the standard

; Implicit flush tells PHP to tell the output layer to flush itself
