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" } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63715&edit=1
