title: What is difference between FILTER_SANITIZE_FULL_SPECIAL_CHARS and htmlspecialchars?
body: <p>I have a textarea which will be available to users as comment box so any sort of inputs are acceptable but that should be accepted only as text and not code. Basically I want to protect my database. I don't want to strip tags or such thing, I just want that if any users even inputs a code that should be stored in database as text and shouldn't be causing any harm to database. So came across these two <code>php</code> functions now I am not sure which one ofthese I should use as I am not able to understand difference in them.</p>
