Hook a function with uneditable method in PHP

Question

I want to know if this is possible.

Imagine that I am using a PHP library Class which I can not modify. However I want to hook to its method somehow, that whenever it's called, my custom code executes.

For example:

<?php

function uneditable() {
    // does something
}

// my code:
if(<uneditable is called>){
    // do this
}

Is it possible in PHP somehow?

Note: I'm trying to do this with WordPress, as I have to detect execution of some method in a third party plugin which doesn't provide hooks to the endpoint that i'm trying to hook into. I don't want to edit the plugin itself as it will get updated anytime and my code will be gone.

Thank and Regards.

Answer 1

As it is wordpress you can use the Wordpress hook .

Here is an example.

<?php

 /**
  * Define the action and give functionality to the action.
  */
 function uneditable() {
   do_action( 'uneditable' );
 }

 /**
  * Register the action with WordPress.
  */
 add_action( 'uneditable', 'uneditable_hook' );
 function uneditable_hook() {
   echo 'This is a custom action hook.';
 }

You can read more about add_action and do_action

What you need is abstract method in abstract class. That will force the child class to implement the method.

abstract class A {


abstract function a() {}

}

class B extends A {

function a () {


// write your code here.
}
}
