Why can I do:

<?
$my_func = "function_name";
$result = $my_func( $arg1, $arg2, $arg3 );

but NOT do:

<?
$my_ob->func = "function_name";
$result = $my_ob->func( $arg1, $arg2, $arg3 );
?>

to call function_name() with the apropriate arguments? Do I have to do something to the object-property reference to make it work? Currently I'm doing:

<?
$my_ob->func = "function_name";
$f = $my_ob->func;
$result = $f( $arg1, $arg2, $arg3 );
?>

which works, but it's nyaaagh!

I don't really use PHP (I'm aa C++ coder), but my guess is what's happening
is the PHP interpreter is trying to dereference the function pointer against my_obj's class, rather than looking for a global function to call.
