This article mainly shares with you how to use __call() and __callStatic() in PHP. I hope it can help you. I won’t explain too much about the use of these two methods. Through the example code and results, everyone can understand the functions of the two more clearly.

1.__call() method. When calling a method that is not declared in the class, you can call the __call() method instead of declaring a method. Accepts method name and array as parameters.

Code example:

<?php  
class test{  
//魔术方法__call  
/* 
$method 获得方法名 
$arg 获得方法的参数集合 
*/  
public function __call($method,$arg){  
    echo &#39;你想调用我不存在的方法&#39;,$method,&#39;方法<br/>&#39;;  
    echo &#39;还传了一个参数<br/>&#39;;  
    echo print_r($arg),&#39;<br/>&#39;;  
  }   
$list=new test();  
$list->say(1,2,3);  
  
?>

Execution result:

You want to call my non-existent method say method
also passed it One parameter
Array ([0] => 1 [1] => 2 [2] => 3 )

##2.__callStatic ()method. This method has appeared since PHP5.3 and is used when creating a static method to call a method that does not exist in the class. Same as the __call() method, accepting method name and array as parameters.

Code example:

<?php  
class test{  
//魔术方法__callStatic 
/* 
$method 获得方法名 
$arg 获得方法的参数集合 
*/  
//魔术方法__callStatic  
public static function __callStatic($method,$arg){  
  
    echo &#39;你想调用我不存在的&#39;,$method,&#39;静态方法<br/>&#39;;  
    echo &#39;还传了一个参数<br/>&#39;;  
    echo print_r($arg),&#39;<br/>&#39;;  
  }  
  
}  
test::cry(&#39;痛哭&#39;,&#39;鬼哭&#39;,&#39;号哭&#39;);  

?>

Execution result:


You want to call my non-existent cry static method
Also passed a parameter
Array ([0] => Cry[1] => Ghost cry[2] => Cry)
