note 86407 added to function.is-array

alex frase's example is fast but elanthis at awesomeplay dot com's example is faster and Ilgar's modification of alex's code is faulty (the part " || $_array[$k] !== $v"). Also, Ilgar's suggestion of giving a false return value when the variable isnt an array is not suitable in my opinion and i think checking if the array is empty would also be a suitable check before the rest of the code runs. So here's the modified (is_vector) version function is_assoc( &$array ) { if ( !is_array($array) || empty($array) ) { return -1; } $next = 0; foreach ( $array as $k => $v ) { if ( $k !== $next ) return true; $next++; } return false; } and the modified (alex's is_assoc) version function is_assoc($_array) { if ( !is_array($_array) || empty($array) ) { return -1; } foreach (array_keys($_array) as $k => $v) { if ($k !== $v) { return true; } } return false; } ---- Server IP: 69.147.83.197 Probable Submitter: 86.96.228.85 (proxied: 92.96.223.116) ---- Manual Page -- http://www.php.net/manual/en/function.is-array.php Edit -- https://master.php.net/note/edit/86407 Del: integrated -- https://master.php.net/note/delete/86407/integrated Del: useless -- https://master.php.net/note/delete/86407/useless Del: bad code -- https://master.php.net/note/delete/86407/bad+code Del: spam -- https://master.php.net/note/delete/86407/spam Del: non-english -- https://master.php.net/note/delete/86407/non-english Del: in docs -- https://master.php.net/note/delete/86407/in+docs Del: other reasons-- https://master.php.net/note/delete/86407 Reject -- https://master.php.net/note/reject/86407 Search -- https://master.php.net/manage/user-notes.php
