note 126794 added to function.array-is-list

Polyfills that call array_keys(), array_values() or range() are inefficient because they create new arrays unnecessarily. Please use this polyfill instead which creates no new arrays and only does a single pass over the given array. <?php if (!function_exists("array_is_list")) { function array_is_list(array $array): bool { $i = 0; foreach ($array as $k => $v) { if ($k !== $i++) { return false; } } return true; } } ?> ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.135 (proxied: 2405:6e00:2f77:2101:c9d0:58a1:e705:bc40) ---- Manual Page -- https://php.net/manual/en/function.array-is-list.php Edit -- https://main.php.net/note/edit/126794 Del: integrated -- https://main.php.net/note/delete/126794/integrated Del: useless -- https://main.php.net/note/delete/126794/useless Del: bad code -- https://main.php.net/note/delete/126794/bad+code Del: spam -- https://main.php.net/note/delete/126794/spam Del: non-english -- https://main.php.net/note/delete/126794/non-english Del: in docs -- https://main.php.net/note/delete/126794/in+docs Del: other reasons-- https://main.php.net/note/delete/126794 Reject -- https://main.php.net/note/reject/126794 Search -- https://main.php.net/manage/user-notes.php
