PHP Call a instance method with call_user_func within the same class

Question

I'm trying to use call_user_func to call a method from another method of the same object, e.g.

class MyClass {     public function __construct()     {         $this->foo('bar');     }     public function foo($method)     {         return call_user_func(array($this, $method), 'Hello World');     }      public function bar($message)     {         echo $message;     } } 

new MyClass; Should return 'Hello World'...

Does anyone know the correct way to achieve this?

Many thanks!

Answer 1

The code you posted should work just fine. An alternative would be to use "variable functions" like this:

public function foo($method) {      //safety first - you might not need this if the $method      //parameter is tightly controlled....      if (method_exists($this, $method))      {          return $this->$method('Hello World');      }      else      {          //oh dear - handle this situation in whatever way          //is appropriate          return null;      } }

This works for me:

<?php class MyClass {     public function __construct()     {         $this->foo('bar');     }     public function foo($method)     {         return call_user_func(array($this, $method), 'Hello World');     }      public function bar($message)     {         echo $message;     } }  $mc = new MyClass(); ?> 

This gets printed out:
