note 86658 added to function.is-array

yousef's example was wrong because is_vector returned true instead of false if the key was found here is the fixed version (only 2 lines differ) <?php function is_vector( &$array ) { if ( !is_array($array) || empty($array) ) { return -1; } $next = 0; foreach ( $array as $k => $v ) { if ( $k !== $next ) return false; $next++; } return true; } ?> ---- Server IP: 64.71.164.2 Probable Submitter: 68.55.100.7 ---- Manual Page -- http://www.php.net/manual/en/function.is-array.php Edit -- https://master.php.net/note/edit/86658 Del: integrated -- https://master.php.net/note/delete/86658/integrated Del: useless -- https://master.php.net/note/delete/86658/useless Del: bad code -- https://master.php.net/note/delete/86658/bad+code Del: spam -- https://master.php.net/note/delete/86658/spam Del: non-english -- https://master.php.net/note/delete/86658/non-english Del: in docs -- https://master.php.net/note/delete/86658/in+docs Del: other reasons-- https://master.php.net/note/delete/86658 Reject -- https://master.php.net/note/reject/86658 Search -- https://master.php.net/manage/user-notes.php
