Note Submitter: Rob ---- Here's another way to see if an array is associative (nobody actually uses the term "vector" ;-) ). It's a little less breakable than the other current leading suggestion, and it's somewhat faster. Tested with 1000 iterations of two simple arrays (one associative, one not). <?php function array_is_associative ($array) { if ( is_array($array) && ! empty($array) ) { for ( $iterator = count($array) - 1; $iterator; $iterator-- ) { if ( ! array_key_exists($iterator, $array) ) { return true; } } return ! array_key_exists(0, $array); } return false; } ?>
