MySQL php prepared or parameterized

I want to know

I have researched for preventing MySQL injection

As a result I found the words prepared and parameterized

My question is

Do I need to make the php parameterized and can send normal quiries from app using web component

Or I need to send parameterized quireies and can use same php as provided by taifun

Please i want know this do not unlist this
I haven’t mentioned deephost here

I want to send quiries from app itself using web component by using taifun php

what i did is make php parameterized and send actionid from app using web component.
it’s more clean on kodular code, and avoiding send the queries over the net.
dont forget using https
and in my case, before i send the string over the net, I encrypt the string first.
