note 124349 added to function.is-array

While this is implied in the definition I have verified (PHP 5.5.38, 7.1.32, 7.2.23 and 7.3.10) that: is_array(null) == false So there is no need for this: if (isset($arr) && is_array($arr)) { /* … */ } The same can be accomplished with: if (is_array($arr)) { /* … */ } The value null is often a special case so I think this should be included in the documentation. ---- Server IP: 208.43.231.9 Probable Submitter: 185.85.3.168 (proxied: 80.133.227.89) ---- Manual Page -- http://php.net/manual/en/function.is-array.php Edit -- https://master.php.net/note/edit/124349 Del: integrated -- https://master.php.net/note/delete/124349/integrated Del: useless -- https://master.php.net/note/delete/124349/useless Del: bad code -- https://master.php.net/note/delete/124349/bad+code Del: spam -- https://master.php.net/note/delete/124349/spam Del: non-english -- https://master.php.net/note/delete/124349/non-english Del: in docs -- https://master.php.net/note/delete/124349/in+docs Del: other reasons-- https://master.php.net/note/delete/124349 Reject -- https://master.php.net/note/reject/124349 Search -- https://master.php.net/manage/user-notes.php
