Question

here is an example class:

public class example
 {
     private $foof;         

     public function __construct()
     {
          $this->foof = $this->foo;
     }

     public function foo($val=0)
     {
             // do something...
     }
 }

So basically, in the constructer of the sample code, is it possible to assign a class method to a variable?

Ultimately what i want is to have an associative array with all the class methods aliased in it…that possible in php?

Answer 1

In PHP5.3+ (which you should be using anyway!) you can simply create an anonymous function which calls your method:

$this->foof = function() {
    $this->foo(1);
};

However, you cannot call it using $this->foof() – you have to assign it to a variable first: $foof = $this->foof; $foof();

In older PHP versions you cannot easily do this – create_function() does not create a closure so $this is not available there.
