# runkit_import

(PECL runkit >= 0.7.0)

runkit_import — Process a PHP file importing function and class definitions, overwriting where appropriate

### 说明

runkit_import ( string `$filename` [, int `$flags` = RUNKIT_IMPORT_CLASS_METHODS ] ) : bool

Similar to include however any code residing outside of a function or class is simply ignored. Additionally, depending on the value of `flags`, any functions or classes which already exist in the currently running environment may be automatically overwritten by their new definitions.

### 参数

`filename`

  Filename to import function and class definitions from

`flags`

  Bitwise OR of the RUNKIT_IMPORT_* family of constants.

### 返回值

成功时返回 `TRUE`， 或者在失败时返回 `FALSE`。

### 范例
