How to make a secure database query?

Question

PHP

Good afternoon. Not so long ago I did a test task in one Internet agency (for the position of an intern, not even a junior), they indicated an error about unsafe access to the database on the add.php page. Now I'm just curious, how can this be done in Bitrix?

));
