note 93433 added to function.is-array

This is the fastest way I've come across to determine if an array is associative or purely numerically keyed. It runs between 2x and 3x faster than any other method I've found in the comments. Either way its pretty slow on large arrays, in the 30ms range for 100,000 elements. Other methods were in the 100-150ms range. function is_assoc( $array ) { $i=0; foreach($array as $k=>$v) { if ( $k !== $i OR (int)$k !== $k ) { return TRUE; } $i++; } return FALSE; } ---- Server IP: 216.235.13.26 Probable Submitter: 24.71.236.35 ---- Manual Page -- http://www.php.net/manual/en/function.is-array.php Edit -- https://master.php.net/note/edit/93433 Del: integrated -- https://master.php.net/note/delete/93433/integrated Del: useless -- https://master.php.net/note/delete/93433/useless Del: bad code -- https://master.php.net/note/delete/93433/bad+code Del: spam -- https://master.php.net/note/delete/93433/spam Del: non-english -- https://master.php.net/note/delete/93433/non-english Del: in docs -- https://master.php.net/note/delete/93433/in+docs Del: other reasons-- https://master.php.net/note/delete/93433 Reject -- https://master.php.net/note/reject/93433 Search -- https://master.php.net/manage/user-notes.php
