$foundme=0;
while ($rowtop = $STH2->fetch())

}
$q = $this->update("
UPDATE `users`

Well, if you use PDO try this :
$bdd = /* your database connexion */
$sql = "UPDATE `user`
SET `first_name` = :first_name, `last_name` = :last_name
WHERE `member_id` = 2001;";
$req = $bdd->prepare($sql);
$req->bindParam(':first_name', $first_name);
$req->bindParam(':last_name', $last_name);
$req->execute();
If you don't use PDO, the syntax may differ but the logic should be the same just adapt :
Create the query with some 'param', here :first_name and :last_name
Prepare your query
Bind the param with the actual value, here $first_name and $last_name
Then execute the query
Is it what you are looking for?
