是否可以使用GET数据在PHP中调用特定函数？ [重复]

问题描述：

This question already has an answer here:

How to call PHP function from string stored in a Variable 15 answers

I have a file functions.php which has multiple functions like:

function do_this(){
}

function do_that(){
}

Now, I am thinking doing something weird like calling that function from URL:

functions.php?func=do_that

Now, I added this lines of code to functions.php

if(isset($_GET["func"])){
    $func = $_GET["func"];
    //How to call that function with name "$func"

}

Any great brains out there? Let me know. If that's not possible, then also lemme know. Coz I have to think of a new approach in my work.

如何从存储在变量中的字符串调用PHP函数 15 answers span> li> ul> div>

我有一个文件 functions.php strong>，它有多个函数，如： p>

  function do_this（）{
} 
 
函数do_that（）{
} 
   code>  pre> 
 
 现在，我正在考虑做一些奇怪的事情，比如从URL调用该函数： p> 
 
 
 
  functions.php？ func  strong> =  do_that  em>  p> 
  blockquote> 
 
 
现在，我将这行代码添加到 functions.php  strong  >  p> 
 
 
 如果（isset（$ _ GET [ “FUNC”]  ））{
 $ func = $ _GET [“func”]; 
 //如何调用名为“$ func”的函数
 
} 
  code>  pre> 
 
  那里有什么大脑？ 让我知道。 如果这不可能，那么也知道。 因为我必须在工作中考虑一种新的方法。 p>

答

All you need to do is to call the function as you get the $_GET variables like this:

if(isset($_GET["func"])){
    $func = $_GET["func"];
    $func();

}
