Bug description:usort not sorting correctly
Description:
------------
Doesn't sort correctly. I'm attempting to sort so that the values 'c' and
'd' show
up on the top in that order followed by the other values sorted using
strcasecmp.
'c' and 'd' do show up on the top of the sorted array but not in that
order.
Test script:
---------------
$x = array('a','b','c','d','e','f');
usort($x, function ($a, $b) {
// must return an integer less than, equal to, or greater than zero
if the first argument is considered to be respectively less than, equal to,
or greater than the second
static $custom_sort_data = array(
'c' => 256,
'd' => 255,
);
if (isset($custom_sort_data[$a]))
return -$custom_sort_data[$a];
if (isset($custom_sort_data[$b]))
return $custom_sort_data[$b];
return strcasecmp($a, $b);
});
var_dump($x);
Expected result:
----------------
array(6) { [0] => string(1) "c" [1] => string(1) "d" [2] => string(1) "a"
[3] =>
string(1) "b" [4] => string(1) "e" [5] => string(1) "f" }
Actual result:
--------------
array(6) { [0] => string(1) "d" [1] => string(1) "c" [2] => string(1) "a"
[3] =>
string(1) "b" [4] => string(1) "e" [5] => string(1) "f" }
