在运行时修改方法/函数 [英] modify a method/function at runtime

问题描述

我一直在看php反射方法，我想做的是在方法打开之后和任何返回值之前注入一些代码，例如我想改变:

I've been looking at the php reflection methods, what i want to do is inject some code after the method is opened and before any return value, for example i want to change:

function foo($bar)
{
    $foo = $bar ;
    return $foo ;
}

并向其中注入一些代码，例如:

And inject some code into it like:

function foo($bar)
{
    //some code here
    $foo = $bar ;
    //some code here
    return $foo ;
}

可能吗?

推荐答案

查看 anonymous功能.如果您可以运行 PHP 5.3，那可能更符合您要执行的操作.

Look into anonymous functions. If you can run PHP 5.3 that might be more along the lines of what you're trying to do.
