It does add them correctly if even one parameter appears. Note that filter_var_array($_GET, $filters, true) does add the empty fields correctly. Test script: --------------- $getFilters = [ 'id'=>['filter'=>FILTER_VALIDATE_INT, 'flags'=>FILTER_REQUIRE_SCALAR, 'options'=>['min_range'=>1] ], 'name'=>FILTER_UNSAFE_RAW ]; echo '$_GET: <br>'; var_dump($_GET); $req = filter_input_array(INPUT_GET, $getFilters, true); echo '<hr>$req:<br>'; var_dump($req); echo '<hr>$reqGet<br>'; $reqGet = filter_var_array($_GET, $getFilters, true); var_dump($reqGet); Actual result: -------------- Execute the above script with no query string gives this result: $_GET: array (size=0) empty $req: null $reqGet array (size=2) 'id' => null 'name' => null ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70263&edit=1
