Correct polyfill (one that doesn't make copies of arrays, and that doesn't make use of the IAP) is: <?php if(!function_exists('array_key_first')){ function array_key_first(array $array){ if($array === []){ return NULL; } foreach($array as $key => $_) return $key; } } if(!function_exists('array_key_last')){ function array_key_last(array $array){ if($array === []){ return NULL; } return array_key_first(array_slice($array, -1)); } } ?> ---- Server IP: 208.43.231.9 Probable Submitter: 185.85.3.142 (proxied: 79.31.59.76) ---- Manual Page -- http://php.net/manual/en/function.array-key-last.php Edit -- https://master.php.net/note/edit/123836 Del: integrated -- https://master.php.net/note/delete/123836/integrated Del: useless -- https://master.php.net/note/delete/123836/useless Del: bad code -- https://master.php.net/note/delete/123836/bad+code Del: spam -- https://master.php.net/note/delete/123836/spam Del: non-english -- https://master.php.net/note/delete/123836/non-english Del: in docs -- https://master.php.net/note/delete/123836/in+docs Del: other reasons-- https://master.php.net/note/delete/123836 Reject -- https://master.php.net/note/reject/123836 Search -- https://master.php.net/manage/user-notes.php
