重新定义内置的PHP函数 [英] Redefine Built in PHP Functions

问题描述

我想重新定义PHP中已经构建的某些函数，例如echo()或time()-我不需要在一个测试脚本中就全局定义这些函数.

I would like to redefine certain functions in PHP that are already built for example, echo() or time() - I don't need to define these functions globally, just within a single script for testing.

我认为这可以在Perl中完成，但可以在PHP中完成-可以吗?

I think this can be done in Perl but in PHP - Is this possible?

推荐答案

runkit_function_redefine —用新的实现替换函数定义

runkit_function_redefine — Replace a function definition with a new implementation

注意:默认情况下，只能删除，重命名或删除用户空间功能 修改的.为了覆写 内部功能，必须启用 runkit.internal_override设置 在php.ini中.

Note: By default, only userspace functions may be removed, renamed, or modified. In order to override internal functions, you must enable the runkit.internal_override setting in php.ini.
