如何从字符串变量中创建函数？

Question

如何从字符串中创建函数？我是php编程的新手，想要下面代码的解决方案。

如果我想访问test2.php的页面？page = test下面的类：

class test{
   public static function getTest(){
      //code here....
   };
}

并想使用变量访问test2.php？page = test，那我该怎么办？

require_once "test.php";
$variabe = $_GET['page'];

test::get . ucfirst($variable) . ();

你可以这样做：

<?php
class test{
   public static function getTest(){
      echo 'getTest()!!';
   }
}

$variable = 'Test';

// since we are interpolating a raw string, input from $_GET, and a function we need to let PHP know to fully complete this string before using it as a function call
test::{"get".ucfirst($variable)}();



// Build the full method name ahead of time and you can just call it using the variable
$variable2 = 'getTest';

test::$variable2();

输出：

getTest()!!
