I suppose codeigniter has built-in defense system, but how properly use it?
e.g. - we have user's input - Name, password, message?
Do i have to manually call native php functions -
strip_tags($_POST['name']);
htmlentities($_POST['name'], ENT_QUOTES, "UTF-8");
htmlspecialchars($_POST['name'], ENT_QUOTES);
Or CI - automatically checks that?
Can you explain everything in details, because - safety first☺
