note 103781 deleted from function.is-array by danbrown

Note Submitter: no at thanks dot com ---- Yet another is_assoc function: <?php public static function is_assoc($arr) { if(!is_array($arr)) return false; $i=0; foreach($arr as $k=>$v) { if($k !== $i) return true; ++$i; } return false; } ?> This one checks that all the keys are numbers and are in sequence. This should be more similar how json_encode works when determining how the output should look. If they aren't in sequence, 0,1,2... then obviously they've been modified in some way, and thus are probably significant.
