Anti-Sql_injection alittle question

[Tannous]

Hey Guys, I wanted to ask about adding an anti sqli to my website .. so if I want to add a file (like antisqli.php)
should I make any coding to the web i'm using or just adding this to pages:

include "antisqli.php";

or require (instead of include dunnu exactly what's the difference xD)
but my question is:
should I only add this or another thing

--------------------------------
hope you can understand what did I mean xD .. and hope you can help with alittle thing

Require that file after session_start();.

If the file does not exist when using require, it will throw a fatal error.
If the file does not exist when using include, it will throw a warning.
