; PHP's initialization file, generally called php.ini, is responsible for
; configuring many of the aspects of PHP's behavior.

; PHP的初始化文件一般命名为php.ini,负责配置php的许多特性方面

; 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试图从多个位置查找并加载这个配置文件。
; 下面是它的搜索顺序的摘要：
; 1.SAPI模块指定的位置
; 2.PHPRC环境变量指定的位置
; 3.一些在windows预定义的注册表项
; 4.当前工作目录(仅适用于CLI模式)
; 5.web服务器目录(适用于SAPI模块)或PHP所在目录(Windows下其它情况)
; 6.通过--with-config-file-path编译选项指定的目录或者windows目录(c:\windows或者c:\winnt)

; 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.

;该文件的语法非常简单。空白字符和以分号(;)开头的行默认被忽略掉(正如你可能猜到的)。
;区段标题(例如:[Foo])默认也被忽略掉，即使将来他们可能有某种意思。

; 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

; 区段标题指令[PATH=/www/mysite]仅作用于在www/mysite目录下的php文件。
; 区段标题指令[HOST=www.example.com]仅作用于在www.example.com下的php文件。
; 这些特殊的区段的指令集不能被用户自定义的INI文件覆盖或者在运行时。
; 目前，[PATH=]和[HOST=]区段仅在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.

; 设置指令的格式如下：
; directive = value
; 指令名大小写敏感。- 所以foo=bar不同于FOO=bar。
; 这些指令变量是用来配置PHP或者PHP扩展的。
; 没有命名验证。如果因为指令未设置或者拼写错误而导致PHP找不到预期的指令，PHP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})

; 指令值可以是一个字符串，一个数字，一个PHP常量(如：E_ALL或者M_PI)，
; 一个包含(On,Off,True,False,Yes,No 和None)的INI常量或者一个表达式(如：E_ALL & ~E_NOTICE),一个引号括起的字符串("bar")，
; 或者引用之前设置的变量或者指令(例如：${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.

; INI文件中表达式仅使用：位运算符、逻辑非和圆括号：
; | 位或
; ^ 位异或
; & 位与
; ~ 位非
; ! 逻辑非
; 布尔标志用1，On，True或者Yes表示打开。用0，Off,False或者No表示关闭。

; 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'

; 一个空的字符串可以用在等号后不写任何东西表示，或者用none关键字：
; foo =      ;将foo设为空字符串
; foo = None ;将foo设为空字符串
; foo = "None"; 将foo设为字符串'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.

; 如果你在指令值中使用动态扩展(PHP扩展或者Zend扩展)中的常量，
; 那么你只能在加载这些动态扩展的指令行后面使用这些常量。

; 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打包时包含2个INI文件。一个建议在生产环境中使用，一个建议在开发环境中使用。

; 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.

; php.ini-production包含设置保证安全，性能和最佳实践的核心。但是请注意，这些设置可能会打破与旧的
; 或者没有安全意识的应用程序的兼容性。我们推荐在生产或者测试环境使用php.ini-production文件。

; php.ini-development 非常类似于生产版本的变体，但当他发生错误时会展示更详细的信息。
; 我们建议仅在开发环境中使用开发版php.ini。否则应用程序的错误显示会无意中泄漏安全信息。

; This is php.ini-production INI file.
; 这是php.ini-production INI文件。

; 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

; 决定是否允许使用 PHP 代码开始标志的缩写形式（<? ?>）
; 该指令确定PHP是否识别在<?和?>标签之间应当被执行的PHP代码。
; 通常建议使用<?php 和 ?> 并且这个特性应该被禁用，如果启用这个特性可能在生成XML文档时产生问题，

; 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

; 输出缓存机制用来控制PHP在向客户端输出数据(不包括headers和cookies)之前应当缓存多少数据。
; 如果你的应用程序输出超过了这个设置值，PHP将要发送大致如你指定大小的数据块。
; 打开这个设置并管理缓冲的最大值，根据你的应用程序和Web服务器可能会产生一些有意思的副作用。
; 你可以在已经通过print或者echo输出正文内容后，再发送headers和cookies。
; 你也可以看到性能优势，如果你的服务器由于缓存输出而减少的网络数据包发送。在生产环境上，
; 出于性能原因考虑4096字节是一个很好的设置。
; 注意：缓存输出也可以通过缓存控制函数控制。
; 可能的值：
; On = 启用并且缓存是无限的(小心使用)
; Off = 禁用
; 数值 = 启用缓存并且设置最大值，单位为字节
; 注意:  该选项在 CLI SAPI 下总是为 Off

; 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.

; 你可以将脚本的所有输出重定向到一个函数。例如：将output_handler设置为"mb_output_handler"
; 函数，字符的编码将被修改为指定的编码。设置的任何处理函数，将自动的处理输出缓冲。
; 注意: 如果是可移植的脚本就不应该依赖ini中的指令。相反,显式地设置输出处理程序使用ob_start()函数。
; 使用这个ini指令可能会导致问题,除非你知道脚本在干什么。
; 注意：不能同时使用 mb_output_handler() 和 ob_iconv_handler()，也不能同时使用 ob_gzhandler() 
; 和 zlib.output_compression()。
; 注意：如果使用zlib.output_handler指令开启zlib输出压缩，该指令必须为空！！！

; 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-compression

; 使用zlib库实现透明的输出压缩，这个选项的有效值是'off'，'on'或者是字节数(用于压缩缓冲区大小，默认值是4KB)
; 注意：由于压缩性质的不同可能导致结果块的大小不同。PHP输出块是每个压缩结果几百字节的。
; 如果你为了性能更喜欢更大字节的块，另外启用zlib.output_handler。
; 注意：你需要使用zlib.output_handler代替标准的

; Implicit flush tells PHP to tell the output layer to flush itself
; automatically after every output block.  This is equivalent to calling the

; implications and is generally recommended for debugging purposes only.
; http://php.net/implicit-flush

; 本指令不受安全模式打开或者关闭的影响。
; Note:
; 当一个脚本试图用例如 fopen() 或者 gzopen() 打开一个文件时，该文件的位置将被检查。
; 当文件在指定的目录树之外时 PHP 将拒绝打开它。
; 所有的符号连接都会被解析，所以不可能通过符号连接来避开此限制。

; 在 Windows 中，用分号分隔目录。在任何其它系统中用冒号分隔目录。作为 Apache 模块时，父目录中的 open_basedir 路径自动被继承。
; 用 open_basedir 指定的限制实际上是前缀，不是目录名。
; 也就是说“open_basedir = /dir/incl”也会允许访问“/dir/include”和“/dir/incls”，如果它们存在的话。
; 如果要将访问限制在仅为指定的目录，用斜线结束路径名。例如：“open_basedir = /dir/incl/”。

; 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

; E_ALL             - 所有错误和警告(包括从PHP 5.4.0起也包括E_STRICT)
; E_ERROR           - 致命的运行时错误。这类错误一般是不可恢复的情况，例如内存分配导致的问题。后果是导致脚本终止不再继续运行。
; E_RECOVERABLE_ERROR  - 可被捕捉的致命错误。 它表示发生了一个可能非常危险的错误，但是还没有导致PHP引擎处于不稳定的状态。
                        ;如果该错误没有被用户自定义句柄捕获 (参见 set_error_handler() )，将成为一个E_ERROR从而脚本会终止运行。
; E_WARNING         - 运行时警告 (非致命错误)。仅给出提示信息，但是脚本不会终止运行。
; E_PARSE           - 编译时语法解析错误。解析错误仅仅由分析器产生。
; E_NOTICE          - 运行时通知。表示脚本遇到可能会表现为错误的情况，但是在可以正常运行的脚本里面也可能会有类似的通知。
; E_STRICT          - 启用 PHP 对代码的修改建议，以确保代码具有最佳的互操作性和向前兼容性。
; E_CORE_ERROR      - PHP初始化启动过程中发生的致命错误。该错误类似 E_ERROR ，但是是由PHP引擎核心产生的
; E_CORE_WARNING    - PHP初始化启动过程中发生的警告 (非致命错误) 。类似 E_WARNING ，但是是由PHP引擎核心产生的。 
; E_COMPILE_ERROR   - 致命编译时错误。类似 E_ERROR , 但是是由Zend脚本引擎产生的。
; E_COMPILE_WARNING - 编译时警告 (非致命错误)。类似 E_WARNING ，但是是由Zend脚本引擎产生的。
; E_USER_ERROR      - 用户产生的错误信息。类似 E_ERROR , 但是是由用户自己在代码中使用PHP函数 trigger_error() 来产生的。 
; E_USER_WARNING    - 用户产生的警告信息。类似 E_WARNING , 但是是由用户自己在代码中使用PHP函数 trigger_error() 来产生的。 
; E_USER_NOTICE     - 用户产生的通知信息。类似 E_NOTICE , 但是是由用户自己在代码中使用PHP函数 trigger_error() 来产生的。
; E_DEPRECATED      - 运行时通知。启用后将会对在未来版本中可能无法正常工作的代码给出警告。

; 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-errors
; 该指令控制着PHP是否会输出错误,通知和警告。在开发环境下错误的输出是非常有用的，但是在生产环境下，
; 这是非常危险的。根据引发错误的代码,有可能泄漏您应用程序的敏感信息,比如数据库的用户名和密码或者更糟。
; 对于生产环境,我们建议记录错误,而不输出错误。

; set this to 'off' for production servers.
; Default Value: Off
; Development Value: On
; Production Value: Off
; http://php.net/display-startup-errors
; 在PHP启动时发生的错误时是和display_errors分开处理的(即使 display_errors 设置为开启,
;  PHP 启动过程中的错误信息也不会被显示)。PHP默认是抑制来自客户端的错误。
; 在调试配置问题时打开此选项是非常有用的。在生产环境上我们强烈推荐关闭此选项。

; Production Value: On
; http://php.net/log-errors
; 除了显示错误，PHP可以记录错误日志到服务器日志,STDERR或者下面将要提到的error_log指令中配置的文件中。
; 在生产系统中，强烈建议你使用错误日志记录web站点上显示的错误信息。 
; 默认值: Off

; Default Value: On
; Development Value: On
; Production value: On
; http://php.net/html-errors
; 当PHP显示或记录错误,格式化错误消息为HTML格式使其更容易阅读。该指令控制错误消息是否格式化为HTML。
; 在生产环境中要关闭此项。这种新的HTML格式的错误信息是可以点击，
; 它引导用户前往描述该错误或者导致该错误发生的函数的参考信息页面。

html_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
; 如果html_errors设置为On 并且 docref_root 不为空，那么PHP产生可以点击的错误信息，
; 该页面对错误进行具体描述，或者描述了导致该错误发生的函数。
; 为了提供手册的页面，你可以在PHP官方站点下载对应语言的手册，并在ini中设置网址到本地对应的地址。
; 如果你的本地手册拷贝可以使用"/manual/" 访问，你就可以简单的设置 docref_root=/manual/ 。
; 另外你还需要设置 docref_ext 匹配你本地文件的后缀名 docref_ext=.html 。当然也可以设置一个外部的参考地址。
; 通常需要在 docref_root 后面以 "/"结尾
; 注意： 在生产环境中不要使用此指令
;docref_root = "/phpmanual/"

; Example:
; 错误信息之前输出的内容。PHP默认值为空。
;error_prepend_string = "<span style='color: #ff0000'>"

; String to output after an error message. PHP's default behavior is to leave

; 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

; http://php.net/variables-order
; 这个指令决定当PHP启动时那个超全局数据的注册。G,P,C,E & S是下面超全局变量GET,POST,COOKIE,ENV和SERVER的缩写。
; 注册这些数据有性能损失，因为ENV不想其他通用，ENV不推荐在生产环境中使用。
; 你可以使用getenv()函数访问环境变量。
; 按从左到右注册，新值覆盖旧值。
; 举例说，设为"GP"将会导致用POST变量覆盖同名的GET变量，

; This directive determines which super global data (G,P,C,E & S) 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-order

; 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

; http://php.net/register-argc-argv
; 这个指令决定每次运行时PHP是否注册$argv和$argc。当脚本被调用时，$argc包含一个传递给PHP的所有参数的数组。
; $argc包含一个整型的代表参数个数的数字。在命令行模式下，这些数组是非常有用的。当这个指令启用时，
; 每次脚本执行都需要消耗CPU和内存来注册这些变量。出于性能的考虑，在生产环境中，这个指令应该被禁用。
; 注意: 在CLI SAPI的执行模式下，该指令默认为On
; 默认值: On
; 开发模式: Off
; 生产模式: Off

;     session.save_path = "N;/path"
