The fact that you say "$object->$test" suggests that foo() and zoo() are
methods of a class? The following code snippet contains just about every
mechanism for calling a method of a class that there is. The one you'll
probably want is
call_user_func (array ($C, 'B'), 'call 4');
<?
/* Class A has method B */
class A {
function B ($s = "None") {
echo ("<p>input : $s</p>");
}
}
/* $C is an instance of A */
$C = new A ();
/* $D is an array of strings */
$D = array ('item 1', 'item 2', 'item 3', 'item 4');
/* invoke A::B */
A::B ('call 1');
/* invoke $C->B */
$C->B ('call 2');
/* invoke A::B via call_user_func() */
call_user_func (array ('A', 'B'), 'call 3');
/* invoke $C->B via call_user_func() */
call_user_func (array ($C, 'B'), 'call 4');
/* invoke A::B via call_user_func_array() */
call_user_func_array (array ('A', 'B'), array('call 5'));
/* invoke $C->B via call_user_func_array() */
call_user_func_array (array ($C, 'B'), array('call 6'));
/* apply A::B to $D via array_walk() */
array_walk ($D, array ('A', 'B'));
/* apply $C->B to $D via array_walk() */
array_walk ($D, array ($C, 'B'));
?>
