PHP call Function Explained

In PHP, the call function is commonly used to dynamically invoke methods of callable objects. It takes an object and a method name as parameters, and calls the specified method of the specified object. This is very useful when there is a need to dynamically call methods, such as determining the method to call at runtime or specifying the method name using variables.

class MyClass {
    public function myMethod() {
        echo "Hello, World!";
    }
}

$obj = new MyClass();

// 使用call函数调用方法
call([$obj, 'myMethod']);
