Callbacks to an object's functions -- how?

[msangrey]

I'm fairly new to PHP.

I want to store in a variable a value which "points" to one of an object's member functions. Here's code which I thought would do the right thing. It fails with the message: "PHP Fatal error: Call to undefined function: foo() in ./foo.php on line 29" That makes sense to me, but everything I've thought of to fix it, doesn't.

Thanks ahead of time!

<?
class Frump {
var $me;

function Frump(){
$this->me[0] = "foo";
$this->me[1] = "bar";
}

function foo()
{
echo "in foo\n";
}

function bar()
{
echo "in bar\n";
}

function get_the_func($ind){
return $this->me[$ind];
}
}

$foobar = new Frump();

$thing = $foobar->get_the_func(0);
$thing();

?>

Are you looking for this bit of wisdom from the manual?

Yep, that did it.

Actually, that led me to call_user_method() which sounded a lot like what I wanted. However, php4 told me it was deprecated and told me to use the syntax of array(&$obj, "method") with call_user_method(). And THAT worked!

So, I replaced

$thing();

with

call_user_func(array(&$foobar, $thing));

and the world is a happy place.

Thank you!
