While I do not follow your reasoning here either. False is used in many other functions. Previous Comments: ------------------------------------------------------------------------ [2011-07-18 08:00:35] info at cdisun dot de Description: ------------ --- From manual page: http://www.php.net/function.array-search%23Changelog --- array_search gives the result of false when nothing will be found , that is equal to index 0, why not -1. -1 means like in javascript , nothing is found. 0 would than be a correkt index found number. Test script: --------------- <?php $array = array(0 => 'blau', 1 => 'rot', 2 => 'grün', 3 => 'rot'); $key = array_search('grün', $array); // $key = 2; $key = array_search('rot', $array); // $key = 1; $key = array_search('yello', $array); // $key = 0; 0 is equal to false $key = isset( $array[$key] ) ? $key : -1 ; // this solve that 0/false to -1 ?> ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55229&edit=1
