Bug description: 'parent' and 'self' behave differently with call_user_func
Description:
------------
If you use call_user_func(array("parent", "somefunc")), an error is
triggered:
call_user_func(parent::x) [function.call-user-func.html]: First argument
is expected to be a valid callback
However, doing this with 'self' instead of 'parent' works fine, and
behaves as expected.
This may be a recurrence of Bug #26543, in which neither 'parent' nor
'self' could be used in call_user_func, so you might want to take a look
at that.
Reproduce code:
---------------
<?php
class P { function __construct() { $args = func_get_args();
print_r($args); } }
class D { function __construct() { $args = func_get_args();
call_user_func_array(array("parent", "__construct")); } }
class C { function __construct() { $args = func_get_args();
call_user_func_array(array("self", "func"), $args); } function func() {
$args = func_get_args(); print_r($args); } }
$c = new C(1,2,3,4); // behaves as expected
$d = new D(1,2,3,4); // doesn't behave as expected
?>
Expected result:
----------------
Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 )
Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 )
Actual result:
--------------
Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 )

argument is expected to be a valid callback in
