Test script: --------------- <?php $haystack = array(); $haystack[0] = 'German'; $haystack[1] = 'English'; $haystack_lower = array_map('strtolower', $haystack); print_r($haystack); print_r('<br>'); print_r($haystack_lower); print_r('<br>'); if (array_search('german',$haystack_lower) != FALSE) { print_r('match'); } ?> ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70798&edit=1
