Runkit擴展提供了修改常量，用戶定義的函數和用戶定義的類的方法。它還通過沙箱提供自定義的超全局變量和可嵌入的子解釋器。 該軟件包是對[?classkit](https://pecl.php.net/package/classkit)軟件包的補充功能。使用*\--enable-runkit = classkit*選項編譯到./configure時，它將導出與classkit兼容的函數定義和常量。 下載安裝包 [https://pecl.php.net/package/runkit](https://pecl.php.net/package/runkit) ## 運行時配置 這些函數的行為受php.ini中的設置影響。 **Runkit Configuration Options** | 名字 | 默認 | 可修改范圍 | 更新日志 | | --- | --- | --- | --- | | [runkit.superglobal](https://www.php.net/manual/zh/runkit.configuration.php#ini.runkit.superglobal) | "" | PHP\_INI\_PERDIR | ? | | [runkit.internal\_override](https://www.php.net/manual/zh/runkit.configuration.php#ini.runkit.internal-override) | "0" | PHP\_INI\_SYSTEM | * [Runkit\_Sandbox](https://www.php.net/manual/en/runkit.sandbox.php)— Runkit沙箱類-PHP虛擬機 * [Runkit\_Sandbox\_Parent](https://www.php.net/manual/en/runkit.sandbox-parent.php)— Runkit防沙箱類 * [runkit\_class\_adopt](https://www.php.net/manual/en/function.runkit-class-adopt.php)—將基類轉換為繼承的類，并在適當時添加祖先方法 * [runkit\_class\_emancipate](https://www.php.net/manual/en/function.runkit-class-emancipate.php)—將繼承的類轉換為基類，刪除范圍為祖先的任何方法 * [runkit\_constant\_add](https://www.php.net/manual/en/function.runkit-constant-add.php)—與define（）類似，但也允許在類定義中進行定義 * [runkit\_constant\_redefine](https://www.php.net/manual/en/function.runkit-constant-redefine.php)—重新定義一個已經定義的常量 * [runkit\_constant\_remove](https://www.php.net/manual/en/function.runkit-constant-remove.php)—刪除/刪除一個已經定義的常量 * [runkit\_function\_add](https://www.php.net/manual/en/function.runkit-function-add.php)—添加一個新函數，類似于create\_function * [runkit\_function\_copy](https://www.php.net/manual/en/function.runkit-function-copy.php)—將函數復制到新的函數名稱 * [runkit\_function\_redefine](https://www.php.net/manual/en/function.runkit-function-redefine.php)—用新的實現替換函數定義 * [runkit\_function\_remove](https://www.php.net/manual/en/function.runkit-function-remove.php)—刪除函數定義 * [runkit\_function\_rename](https://www.php.net/manual/en/function.runkit-function-rename.php)—更改函數的名稱 * [runkit\_import](https://www.php.net/manual/en/function.runkit-import.php)—處理PHP文件導入功能和類定義，并在適當情況下覆蓋 * [runkit\_lint\_file](https://www.php.net/manual/en/function.runkit-lint-file.php)—檢查指定文件的PHP語法 * [runkit\_lint](https://www.php.net/manual/en/function.runkit-lint.php)—檢查指定的php代碼的PHP語法 * [runkit\_method\_add](https://www.php.net/manual/en/function.runkit-method-add.php)—動態地將新方法添加到給定的類 * [runkit\_method\_copy](https://www.php.net/manual/en/function.runkit-method-copy.php)—將方法從類復制到另一個 * [runkit\_method\_redefine](https://www.php.net/manual/en/function.runkit-method-redefine.php)—動態更改給定方法的代碼 * [runkit\_method\_remove](https://www.php.net/manual/en/function.runkit-method-remove.php)—動態刪除給定的方法 * [runkit\_method\_rename](https://www.php.net/manual/en/function.runkit-method-rename.php)—動態更改給定方法的名稱 * [runkit\_return\_value\_used](https://www.php.net/manual/en/function.runkit-return-value-used.php)—確定是否將使用當前函數的返回值 * [runkit\_sandbox\_output\_handler](https://www.php.net/manual/en/function.runkit-sandbox-output-handler.php)—指定一個函數以捕獲和/或處理來自runkit沙箱的輸出 * [runkit\_superglobals](https://www.php.net/manual/en/function.runkit-superglobals.php)—返回已注冊超全局變量的數字索引數組
