;;;;;;;;;;;;;;;;;;;
; 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，它是负责配置PHP的行为参数
; 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会从一些本地路径尝试查找并加载这个配置。
; 以下是一些搜索顺序的总结：1、SAPI模块的具体位置 2、PHP的环境变量 3、Windows上的一些预定义的注册表键值 4、当前工作目录 5、WEB服务器目录或PHP目录 6、编译时间选项的配置文件目录或windows目录
; 查阅PHP文档获得更多具体信息
; 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.
; 本文件语法极其简单。空白和以分号开始的行被默认为忽略（如你所想）。部分消息头也被默认为忽略（例如 Foo），甚至尽管他们可能在将来有用。
; 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.
; [PATH=/www/mysite]的指令只应用于在的指令只应用于在/www/mysite目录下的PHP文件。[HOST=www.example.com]的指令只应用于在www.example.com下使用的PHP文件。一些特殊的指令设置不会被个人自定义的INI文件或在运行时的设置所覆盖重写。当前，[PATH=]和[HOST=]部分只在CGI/FastCGI模式下有效
; 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.
; 指令规定使用以下语法：1、指令名称 = 指令值 2、指令名字区分大小写 3、指令变量用于配置PHP或PHP扩展 4、文件没有指令名验证。假如PHP因为没有设置或键入错误，而不能找到一个期望的指令，它会使用一个默认的值
; 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（例如E_ALL M_PI），一个INI常量（On, Off, True, False, Yes, No and None）或一个表达式（例如 E_ALL & ~E_NOTICE），一个加上引号的字符串（"bar"），或一个以前设置变量和指令的引用（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
; 在INI文件中表达式仅限于使用按位运算符和圆括号
; 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.
; 布尔标记可以使用值1, On, True 或 Yes打开。他们可以使用值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:
; 一个空字符串可以被指定即在等号后什么都不写，或者使用None关键字
; 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.
; 假如你在你的指令值中使用常量，而且这些常量属于一个动态加载的扩展（无论是PHP扩展或是Zend扩展），你可能需要在加载这些扩展的行后使用这些常量。

; 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打包两个INI文件（INI初始化文件、配置文件）。一个被推荐用于成品环境，一个被推荐用于开发环境。
; 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成品环境设置文档包含设置保持安全性、性能和核心的最佳范例。但是请注意，这些设置可能对老程序或安全性系数低的程序没有很好兼容性。我们推荐在成品和测试环境中使用成品环境设置文件
; php.ini-development is very similar to its production variant, except it's
; much more verbose when it comes to errors. We recommending using the
; development version only in development environments as errors shown to
; application users can inadvertently leak otherwise secure information.
; PHP开发环境设置文件和它的成品变体非常相似，除了当涉及到错误时候它比较繁琐外。我们推荐仅在开发环境中使用此配置，因为错误显示给程序用户会无意中泄露其他方面的安全信息。

; 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.

; This directive determines whether or not PHP will recognize code between
; <? and ?> tags as PHP source which should be processed as such. It's been
; recommended for several years that you not use the short tag "short cut" and
; instead to use the full <?php and ?> tag combination. With the wide spread use
; of XML and use of these tags by other languages, the server can become easily
; confused and end up parsing the wrong code in the wrong context. But because
; this short cut has been a feature for such a long time, it's currently still
; supported for backwards compatibility, but we recommend you don't use them.
; Default Value: On

; 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-buffering
output_buffering = 4096
; 控制缓冲区域大小，此缓冲区只对echo print等有用，cookie header 不操作
; Output Control 可以让你自由控制脚本中数据的输出，如：
当你想在数据已经输出后，再输出文件头的情况。输出控制函数不会作用于 header() 或 setcookie()所发送的文件头信息(标头)产生影响,只对那些类似于 echo() 和 PHP 代码的数据块有作用，它会将这些输出缓存起来，而不是直接就输出到浏览器。
; 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 =
; 回调函数，会自动执行缓冲区中的数据
; 该选项可将脚本所有的输出，重定向到一个函数。例如，将 output_handler 设置为 mb_output_handler() 时，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。
; 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.

; 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 SAPI
implicit_flush = Off
; 打开或关闭绝对刷新，默认为关闭(但受implicit_flush选项的制约)。所谓绝对刷新，即当有输出语句(e.g. echo)被执行时，便把输出直接发送到浏览器，而不再需要调用 flush()或等到脚本结束时才输出。
; The unserialize callback function will be called (with the undefined class'
; name as parameter), if the unserializer finds an undefined class

; 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. This directive is
; *NOT* affected by whether Safe Mode is turned On or Off.
; http://php.net/open-basedir
;open_basedir =
; 将php允许操作的所有文件包括文件本身都限制在此组目录列表下。当一个脚本试图打开一个指定目录树之外的文件时，将遭到拒绝。所有的符号连接都会解析，所以不可能通过符号连接来避开此限制。特殊值'.'指定了存放该脚本的目录将被当做基准目录（相对）。但这有些危险，因为脚本的工作目录可以轻易被chdir改变。对于共享服务器，在httpd.conf中灵活设置该指令将变得非常有用。在windows中分号分隔目录，unix系统中用冒号分隔目录。作为apache模块时，父目录中的open_basedir路径将自动被继承。指定的限制实际上是一个前缀，而非一个目录名。默认是允许打开所有文件。
; open_basedir可将用户访问文件的活动范围限制在指定的区域，通常是其家目录的路径，也
可用符号"."来代表当前目录。注意用open_basedir指定的限制实际上是前缀,而不是目录名。 举例来说: 若"open_basedir = /dir/user", 那么目录 "/dir/user" 和 "/dir/user1"都是
可以访问的。所以如果要将访问限制在仅为指定的目录，请用斜线结束路径名。例如设置成:
"open_basedir = /dir/user/"

; 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)
; 所有错误和警告
; E_ERROR - fatal run-time errors
; 致命的运行时错误
; E_RECOVERABLE_ERROR - almost fatal run-time errors
; 接近致命的运行时错误，若未被捕获则视同E_ERROR
; E_WARNING - run-time warnings (non-fatal errors)
; 运行时警告 非致命性错误
; E_PARSE - compile-time parse errors
; 编译时解析错误
; 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's automatically initialized to an
; empty string)
; 运行时提醒（经常是bug，也可能是有意的）
; 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
; 编码标准化警告 建议如何修改以向前兼容
; E_CORE_ERROR - fatal errors that occur during PHP's initial startup
; php启动时初始化过程中的致命错误
; E_CORE_WARNING - warnings (non-fatal errors) that occur during PHP's
; initial startup
; php启动时初始化过程中的警告
; E_COMPILE_ERROR - fatal compile-time errors
; 编译时的致命性错误
; E_COMPILE_WARNING - compile-time warnings (non-fatal errors)
; 编译时警告

; 用户自定义的致命错误
; E_USER_WARNING - user-generated warning message
; 用户自定义的警告
; E_USER_NOTICE - user-generated notice message
