Yep, you should never use NULL in your code, the following is =
catastrophically bad...

=20
$search =3D ($_GET['q'] ?? NULL);

$search =3D (isset($_GET['q']) ? $_GET['q'] : NULL); // Pre PHP 7
=20
$search =3D filter_input(INPUT_GET, 'q');
=20
$search =3D $request->input('q'); // Laravel
$search =3D $request->get('q'); // Symfony
$search =3D $this->request->getQuery('q'); // CakePHP
$search =3D $request->getGet('q'); // CodeIgniter

$search =3D json_decode('{"q":null}');


And all fields in the database must be set to NOT NULL, never use things =
like LEFT JOIN, etc... :-(
