PHP Bug Type: Zend Engine 2 problem
Bug description: Inconsistent comparing
Description:
------------
The way in which elements of an array are compared is inconsistent.
Reproduce code:
---------------
$a = $c = array("101a","100","6");
$b = $d = array("100","6","101a");
// standard comparison:
$f = create_function('$a,$b','return ($a<$b) ? -1:($a>$b ? +1:0);');
asort($a);
asort($b);
uasort($c,$f);
uasort($d,$f);
print_r($a);
print_r($b);
print_r($c);
print_r($d);
Expected result:
----------------
Than I would expect all 'print_r' print arrays with the same order of
values.
I would expect that items implicitly converted into numbers during
comparison should precede those of type string.
Actual result:
--------------
Array
(
[2] => 6
[1] => 100
[0] => 101a
)
Array
(
[2] => 101a
[1] => 6
[0] => 100
)
Array
(
[2] => 6
[1] => 100
[0] => 101a
)
Array
(
[2] => 101a
[1] => 6
[0] => 100
)
