FILTER_VALIDATE_BOOLEAN's default option

I want my query parameter to be true unless explicitly set otherwise.

$a = filter_input(INPUT_GET, 'v', FILTER_VALIDATE_BOOLEAN,
    array('options' => array('default' => true)));
var_dump($a);

However, accessing this script like /test.php?v=false prints bool(true). Moreover, it always print bool(true) on any input.

You need to pass FILTER_NULL_ON_FAILURE as an options flag, so that your code instead of being:

$a = filter_input(INPUT_GET, 'v', FILTER_VALIDATE_BOOLEAN, array('options' => array('default' => true)));

It should be:

$a = filter_input(INPUT_GET, 'v', FILTER_VALIDATE_BOOLEAN, array('options' => array('default' => true), 'flags' => FILTER_NULL_ON_FAILURE));
