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.
