; 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，一般叫作php.ini，負責配置php不少層面的行爲


; 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在多個位置嘗試加載這個配置文件
; 下面是php加載這個文件時的搜索順序：
; 1. SAPI模塊特定的位置
; 2. PHPRC環境變量（PHP5.2.0開始）
; 3. windows下一系列的預約義的註冊表鍵（PHP5.2.0開始）
; 4. 當前工做目錄（除了CLI）
; 5. 網絡服務器目錄（針對SAPI模塊）或者PHP目錄（otherwise in Windows）
; 6. 編譯時--with-config-file-path選項所指的目錄或者windows目錄（C:\windows or C:\winnt）
; 查看PHP文檔得到更多詳細信息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.
; 這個文件的語法是十分簡單的，空白和以「;」開頭的行都是自動忽略的，章節標題（如[Foo]）也是自動忽略的，即便他們可能具備一些實際意義


; 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
; 標題[PATH=/www/mysite]後的指令只應用於/www/mysite目錄下的PHP文件，標題[HOST=www.example.com]後的指令只應用於;在

; www.example.com上的PHP文件，這些特殊的節下面設置的指令不能夠被用戶自定義的INI文件覆寫，或在運行時被重寫。目前[PATH=] 和 

; [HOST=]只在CGI/FastCGI下工做

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.
; 指令規定使用下面的語法：
; directive = value
; 指令的名字是大小寫敏感的，好比foo=bar 和 FOO=bar 是不同的
; 指令是用於配置PHP或PHP擴展的變量。這些名字是不會被驗證的，若是PHP由於指望的指令找不到或是由於指望的指令被寫錯了，它會使用默認值


; 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})
; 這裏的值能夠是字符串，數字，PHP常量（如E_ALL or M_PI），INI文件定義的一個常量（On, Off, True, False, Yes, No 和 None），或者是一個表

; 達式（如E_ALL & ~E_NOTICE），引用字符串，或指向先前定義的變量或指令的引用


; Expressions in the INI file are limited to bitwise operators and parentheses:
; 這個INI文件中的表達式僅僅可使用位運算和括號
; |  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.
; 布爾標識能夠用值1，On，True或者Yes打開，而且能夠用0，Off，False或No關閉

; An empty string can be denoted by simply not writing anything after the equal
; sign, or by using the None keyword:
; 一個空字符串能夠用在等號後面表示不賦值或者使用「None」這個關鍵字來表示

;  foo =         ; sets foo to an empty string
;  foo = None    ; sets foo to an empty string
;  foo = "None"  ; sets foo to the string 'None' 【這個不是空字符串】

; 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.
; 若是你使用常量賦值，而且這些常量時屬於動態加載的擴展的（不管是PHP擴展仍是Zend擴展），那麼你僅僅能夠在加載這個擴展的行以後使用這些常量。

; 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包含兩個INI文件，其中一個建議用在正式上線的環境中，另外一個建議用在開發環境中

; 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擁有對安全、性能和對核心的最佳實踐的設置，可是請注意，這些設置可能在較老或具備較低安全性的應用上會失去兼容性，所

; 以咱們推薦在正式產品和測試環境中都使用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與production十分類似，只是當錯誤發生時，它顯示的越詳細。咱們建議僅僅在開發環境中使用它，由於展現給用戶的錯誤信

; 息可能會不經意間泄露一些安全信息。

; This is php.ini-production INI file.

; Quick Reference ; 快速參考
;;;;;;;;;;;;;;;;;;;
; 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.
; Please see the actual settings later in the document for more details as to why
; we recommend these changes in PHP's behavior.

; 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.
; 這個指令決定是否PHP會將標籤<?和?>之間的代碼識別爲PHP應該執行的源，一般建議使用<?php 和 ?>，而禁止掉這個特性，由於它可能致使在生

; 成XML文檔時出現問題。而後爲了向後兼容，它如今仍是被支持的。注意，這個指令並不控制<?=這個速寫標籤，它可以在這個指令的限制以外使用

; Default Value: On
; Development Value: Off

; 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.
;輸出緩存是一個控制PHP在向客戶端輸出數據（除了頭文件和cookies）時，應該在內部緩存多少數據的一個機制。若是你的應用輸出超出這個設置，

;PHP會將那些數據大體按照你設置的大小分塊輸出。打開這個設置和管理它的最大緩衝區大小可能產生一些有趣的反作用，這取決於您的應用程序和

;web服務器。在你經過print和echo輸出後你仍能夠發送頭部和cookies。若是由於buffered output versus PHP streaming the output as it gets it

;你的服務器發送更少的數據包，你會看到性能優點。在生產服務器上，對於性能來講4096 bytes（字節）是一個好的配置

; 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
; Development Value: 4096
; Production Value: 4096
; http://php.net/output-buffering
; 注意：輸出緩存也能夠經過輸出緩存控制函數受到控制。
; 可能的值

; Off = 關閉
; Integer = 啓動緩存並設置它的最大緩衝字節數
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.
;你能夠將你全部的腳本輸出重定向到一個函數。例如，若是你設置output_handler爲「mb_output_handler」，字符編碼會被透明的轉化爲指定編

;碼。設置任何輸出處理程序會自動打開輸出緩存。

; 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：編寫便攜式腳本的人不該該依賴於這個ini指令，取而代之的是，使用ob-start()明確的設置輸出處理程序。除非你知道腳本在作什麼，不然將有

;可能出現問題。
; Note: You cannot use both "mb_output_handler" with "ob_iconv_handler"
;   and you cannot use both "ob_gzhandler" and "zlib.output_compression".
注意：你不能夠同時使用"mb_output_handler" 和 "ob_iconv_handler"，也不能同時使用"ob_gzhandler" 和 "zlib.output_compression"
; Note: output_handler must be empty if this is set 'On' !!!!
;   Instead you must use zlib.output_handler.

; 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：結果因爲壓縮的塊大小可能會有所不一樣。PHP輸出壓縮後的幾百字節大小的塊，若是爲了更好的性能你想要更大的塊大小，你能夠另外使用

;output_buffering
; Note: You need to use zlib.output_handler instead of the standard
;   output_handler, or otherwise the output will be corrupted.

; You cannot specify additional output handlers if zlib.output_compression
; is activated here. This setting does the same as output_handler but in
; a different order.
;若是激活了zlib.output_compression，你就不能夠指定額外的輸出處理程序。這個設置和output_handler作了一樣的事，只是順序不一樣
; http://php.net/zlib.output-handler
;zlib.output_handler =

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

; and every HTML block.  Turning this option on has serious performance
; implications and is generally recommended for debugging purposes only.
;隱式沖洗告訴PHP去告訴輸出層在每次輸出塊以後自動刪除緩存。這與在每一次調用print()或者echo()和每一個HTML塊輸出後調用PHP的函數flush()是

;等效的。打開這個選項有嚴重的性能影響，通常的，建議只爲了調試纔打開
