Reference to class method php

Question

I'd like to create a variable that 'points' to a class method like this:

$obj = $this->myMethod();
$obj->call();

or

$obj = $myClass->myMethod();
$obj->call();

Is this possible?

Edit:

Why I'd like to be able to do this:

private $default_field_callback = array(
        "methods" => array(
            "timestamp" => array(
                "object" => {object},
                "method" => "getTimestamp",
                "params" => array("Y-m-d H:i:s")
            ),
        )
    );

$obj = $this->myMethod() will result in $obj containing whatever $this->myMethod(); returns, not an "instance" of $this->myMethod(). Why do you want to do this? — random_user_name

I realize that, but I don't want to call $this->myMethod(), I just want a callable object. — ethan476

What's the point of doing this? Can you give us more detail please? — Ryan Fung

I'd like to have an array of callback methods for validating a form. — ethan476

you can make use of call_user_func() with this array structure indicating a class/method call.

$result = call_user_func(array($this,'myMethod'));

http://www.php.net/function.call-user-func read up for more information and parameter usage

Edit: see also call_user_func_array() to feed in your parameters as a single array
