意想不到的功能，它存在，試圖實例

上課的時候

<?php 
class MyClass 
{ 
    private $key; 
    private $location; 

    function __construct($par1Key, $par2Location) 
    { 
     if(empty($par1Key) || empty($par2Location)) 
      throw new Exception("One or more parameters were left empty."); 
     //do stuff 
    } 

    public static function new($par1Key, $par2Location) { 
     try { 
      return new MyClass($par1Key, $par2Location); 
     } catch (Exception $e) { 
      return null; 
     } 
    } 
} 
?>

現在我想，當我需要它在我的項目頁面做到這一點：

<?php 
    require('myclass.php'); 

    function getInfo($location) { 
     $key = 'xyzabc123'; 
     $class = MyClass::new($key, $location); 

     return $class->myMethod(); 
    } 
?>

但它引發錯誤：
