You must use quote. either single or double. It wont affect sql injection.
Sanitize your data before using it in any sql.

$_REQUEST['var'] means a variable var was passed in http request.
$_POST['var'] means a post variable var was passed in http request.

A get or cookie variable var2 will set $_REQUEST['var2'].

When you are strictly expecting a Post variable 'var3' use
$_POST['var3'], not $_REQEUST['var3'].
This is because a $_GET['var3'] will make $_REQEUST['var3'] available
to you which is not what you want.

Correct me if I am wrong.
