How should we call the private method of a class in php? We know that there is a complete reflection API in PHP, and the ability to reverse engineer classes, interfaces, functions, methods and extensions has been added. Then we can call and execute private methods in a class through reflection.

Next let’s take a look at the specific code implementation.

Code implementation:

<?php
 
//MyClass这个类中包含了一个名为myFun的私有方法
class MyClass {
    
    private $tmp = &#39;hello&#39;;
    
    private function myFun()
    {
        echo $this->tmp . &#39; &#39; . &#39;world!&#39;;
    }
}
 
//通过类名MyClass进行反射
$ref_class = new ReflectionClass(&#39;MyClass&#39;);
 
//通过反射类进行实例化
$instance  = $ref_class->newInstance();
 
//通过方法名myFun获取指定方法
$method = $ref_class->getmethod(&#39;myFun&#39;);
 
//设置可访问性
$method->setAccessible(true);
 
//执行方法
$method->invoke($instance);
?>

The above is all the implementation code. Friends can execute the above code locally.
