note 123945 added to function.array-key-last

This polyfill works for PHP 5.6+. It is a slight modification of "wes at nospam dot example dot org"'s example: <?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( $array === [] ) { return null; } // the last 2 args to array_slice are crucial return array_key_first(array_slice($array, -1, null, true)); } } ---- Server IP: 208.43.231.9 Probable Submitter: 82.199.157.34 (proxied: 2604:3d09:6e80:1c70:f586:c121:9f1f:8dea) ---- Manual Page -- http://php.net/manual/en/function.array-key-last.php Edit -- https://master.php.net/note/edit/123945 Del: integrated -- https://master.php.net/note/delete/123945/integrated Del: useless -- https://master.php.net/note/delete/123945/useless Del: bad code -- https://master.php.net/note/delete/123945/bad+code Del: spam -- https://master.php.net/note/delete/123945/spam Del: non-english -- https://master.php.net/note/delete/123945/non-english Del: in docs -- https://master.php.net/note/delete/123945/in+docs Del: other reasons-- https://master.php.net/note/delete/123945 Reject -- https://master.php.net/note/reject/123945 Search -- https://master.php.net/manage/user-notes.php
