note 90929 added to function.is-array

Using empty() in the previous example posted by Anonymous will result in a "Fatal error: Can't use function return value in write context". I suggest using count() instead: <?php function is_assoc($array) { return (is_array($array) && 0 !== count(array_diff_key($array, array_keys(array_keys($array))))); } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 76.30.145.204 ---- Manual Page -- http://www.php.net/manual/en/function.is-array.php Edit -- https://master.php.net/note/edit/90929 Del: integrated -- https://master.php.net/note/delete/90929/integrated Del: useless -- https://master.php.net/note/delete/90929/useless Del: bad code -- https://master.php.net/note/delete/90929/bad+code Del: spam -- https://master.php.net/note/delete/90929/spam Del: non-english -- https://master.php.net/note/delete/90929/non-english Del: in docs -- https://master.php.net/note/delete/90929/in+docs Del: other reasons-- https://master.php.net/note/delete/90929 Reject -- https://master.php.net/note/reject/90929 Search -- https://master.php.net/manage/user-notes.php
