If you're looking to filter an associative array to leave out certain keys, this is not the function to do it. /* * Simple example illustrating how to filter an associative array so as to exclude certain keys in the resulting array */ $array1 = array( 'a' => 1, 'b' => 2, 'c' => 3 ); // let's strip out the keys 'c' and 'b' var_dump( array_diff_key( $array1, array_flip( array( 'b', 'c' ) ) ) ); ---- Server IP: 69.147.83.199 Probable Submitter: 70.55.240.92 ---- Manual Page -- http://php.net/manual/en/function.array-filter.php Edit -- https://master.php.net/note/edit/111730 Del: integrated -- https://master.php.net/note/delete/111730/integrated Del: useless -- https://master.php.net/note/delete/111730/useless Del: bad code -- https://master.php.net/note/delete/111730/bad+code Del: spam -- https://master.php.net/note/delete/111730/spam Del: non-english -- https://master.php.net/note/delete/111730/non-english Del: in docs -- https://master.php.net/note/delete/111730/in+docs Del: other reasons-- https://master.php.net/note/delete/111730 Reject -- https://master.php.net/note/reject/111730 Search -- https://master.php.net/manage/user-notes.php
