note 90101 added to function.array-filter

this actually doesnt use the callback but it's a filter worth mentioning. removes all empty() elements in an array, even multidimensional ones: <?php function array_remove_empty($array) { $new_array = array(); foreach($array as $key => $value) { if(is_array($value)){$value = array_remove_empty($value);} if(!empty($value)){$new_array[$key] = $value;} } return $new_array; } ?> it's inefficient but it's easy to understand and works nonetheless. ---- Server IP: 64.71.164.2 Probable Submitter: 68.230.177.153 ---- Manual Page -- http://www.php.net/manual/en/function.array-filter.php Edit -- https://master.php.net/note/edit/90101 Del: integrated -- https://master.php.net/note/delete/90101/integrated Del: useless -- https://master.php.net/note/delete/90101/useless Del: bad code -- https://master.php.net/note/delete/90101/bad+code Del: spam -- https://master.php.net/note/delete/90101/spam Del: non-english -- https://master.php.net/note/delete/90101/non-english Del: in docs -- https://master.php.net/note/delete/90101/in+docs Del: other reasons-- https://master.php.net/note/delete/90101 Reject -- https://master.php.net/note/reject/90101 Search -- https://master.php.net/manage/user-notes.php
