note 97624 added to function.is-array

In the previous example, why do you have array_keys of array_keys of $array? isn't is_assoc and is_assoc2 functionally the same? function is_assoc($a) { return (is_array($a) && 0 !== count(array_diff_key($a, array_keys(array_keys($a))))); } function is_assoc2($a) { return (is_array($a) && 0 !== count(array_diff_key($a, array_keys($a)))); } ---- Server IP: 69.147.83.197 Probable Submitter: 209.131.48.66 ---- Manual Page -- http://www.php.net/manual/en/function.is-array.php Edit -- https://master.php.net/note/edit/97624 Del: integrated -- https://master.php.net/note/delete/97624/integrated Del: useless -- https://master.php.net/note/delete/97624/useless Del: bad code -- https://master.php.net/note/delete/97624/bad+code Del: spam -- https://master.php.net/note/delete/97624/spam Del: non-english -- https://master.php.net/note/delete/97624/non-english Del: in docs -- https://master.php.net/note/delete/97624/in+docs Del: other reasons-- https://master.php.net/note/delete/97624 Reject -- https://master.php.net/note/reject/97624 Search -- https://master.php.net/manage/user-notes.php
