note 123725 added to function.is-countable

Polyfill written by arisendrake is not quite good. It return FALSE when checking an Simple XML Node but count() works properly on PHP 7.1 and 7.3. Better is this one: <?php if (version_compare(PHP_VERSION, "7.3") < 0 && !function_exists("is_countable")) { function is_countable($var): bool { return (is_array($var) || is_object($var) || is_iterable($var) || $var instanceof Countable); } } ?> ---- Server IP: 208.43.231.9 Probable Submitter: 185.85.3.142 (proxied: 94.75.116.2) ---- Manual Page -- http://php.net/manual/en/function.is-countable.php Edit -- https://master.php.net/note/edit/123725 Del: integrated -- https://master.php.net/note/delete/123725/integrated Del: useless -- https://master.php.net/note/delete/123725/useless Del: bad code -- https://master.php.net/note/delete/123725/bad+code Del: spam -- https://master.php.net/note/delete/123725/spam Del: non-english -- https://master.php.net/note/delete/123725/non-english Del: in docs -- https://master.php.net/note/delete/123725/in+docs Del: other reasons-- https://master.php.net/note/delete/123725 Reject -- https://master.php.net/note/reject/123725 Search -- https://master.php.net/manage/user-notes.php
