note 118170 added to function.array-intersect-key

The $_GET array is: print_r($_GET); Array ( [page] => 1 [keywords] => something [search_in_description] => yes [sort] => up ) I would like to only allow the following keys, and want it in this particular order: $allowed_array = array( 'keywords', 'search_in_description', 'page', 'sort' ); $sorted_array = array_intersect_key($_GET, array_flip($allowed_array)); Then I get this: print_r($sorted_array); Array ( [page] => 1 [keywords] => something [search_in_description] => yes [sort] => up ) And below is what I hoped to get: Array ( [keywords] => something [search_in_description] => yes [page] => 1 [sort] => up ) Can anyone tell me what I am doing wrong or what I should do in order to achieve what want? Thanks. ---- Server IP: 72.52.91.14 Probable Submitter: 50.135.185.80 ---- Manual Page -- http://php.net/manual/en/function.array-intersect-key.php Edit -- https://master.php.net/note/edit/118170 Del: integrated -- https://master.php.net/note/delete/118170/integrated Del: useless -- https://master.php.net/note/delete/118170/useless Del: bad code -- https://master.php.net/note/delete/118170/bad+code Del: spam -- https://master.php.net/note/delete/118170/spam Del: non-english -- https://master.php.net/note/delete/118170/non-english Del: in docs -- https://master.php.net/note/delete/118170/in+docs Del: other reasons-- https://master.php.net/note/delete/118170 Reject -- https://master.php.net/note/reject/118170 Search -- https://master.php.net/manage/user-notes.php
