note 123976 added to function.array-intersect

I wrote this function to recursively replace array keys with array values (flip) and fill values with defined value. it can be used for recursive array intersect functions . <?php function array_values_to_keys_r($array, $fill_value = null) { $flipped = []; foreach ($array as $key => $value) { if (is_array($value)) { $flipped [$key] = array_values_to_keys_r($value); } else { $flipped [$value] = $fill_value; } } return $flipped; } ?> ---- Server IP: 208.43.231.9 Probable Submitter: 185.85.3.195 (proxied: 5.219.143.107) ---- Manual Page -- http://php.net/manual/en/function.array-intersect.php Edit -- https://master.php.net/note/edit/123976 Del: integrated -- https://master.php.net/note/delete/123976/integrated Del: useless -- https://master.php.net/note/delete/123976/useless Del: bad code -- https://master.php.net/note/delete/123976/bad+code Del: spam -- https://master.php.net/note/delete/123976/spam Del: non-english -- https://master.php.net/note/delete/123976/non-english Del: in docs -- https://master.php.net/note/delete/123976/in+docs Del: other reasons-- https://master.php.net/note/delete/123976 Reject -- https://master.php.net/note/reject/123976 Search -- https://master.php.net/manage/user-notes.php
