PHP 执行与变量值相同的方法

mixed call_user_func ( callback $function [, mixed $parameter [, mixed $...]] )

mixed call_user_func_array ( callback $function, array $param_arr )

<?phpfunction barber($type){    echo "You wanted a $type haircut, no problem";}call_user_func(‘barber‘, "mushroom");call_user_func(‘barber‘, "shave");?> 

-----------------或者你可以这样

<?php

function fuck(){ echo ‘fuck‘;}

$a = ‘fuck‘;$a();--------------------------全面的写法

<?php

class test extends  testBase{

function name()
    {
        echo ‘name namenamenamename11111111 ‘;
    }

function pass()
    {
        echo ‘passpasspasspasspasspass22222222222 ‘;
    }

}

class testBase{

function __construct()
    {
        $test_func=$_GET[‘st‘];
        $this->$test_func();
    }
}

new test();
