Question

My problem is this, i have a function which is stored in an array which is a part of a class. I want to call a function from this array using call_user_func() however i can’t seem to figure out how to write this.

Calling a function from an array which is not in a class can be done like such.

 $thearray = array( 0 => 'funcone', 1 => 'functwo');
 call_user_func($thearray[0]);

However when i try to do this to an array which is in a class, it do sent work, i imagine because i need to reference the class somehow. I know that you can call a function from a class like this:

 call_user_func(array($myclass, 'funcone'));

But my question is how would a call a function from an array, which is within a class, by using call_user_func(); i hope somebody can help me with this, i have a feeling that it is just a matter of how its written.

Answer 1

Assuming the array within the class is public, you can do:

call_user_func(array($myclass, $myclass->thearray[0]));

Did that answer your question?

Update:

I tried the following and it worked:

<?php
class Foo {
    public function bar() {
        echo "quux\n";
    }

    public $baz = array('bar');
}

$foo = new Foo();
call_user_func(array($foo, $foo->baz[0]));

shell$ php userfunc.php 
quux
