Call to undefined method PDO::bindParam()

Question

Can someone tell me why I am getting this error? Call to undefined method PDO::bindParam()

Here is what I have, taken right off of PHPs site for stored procedures

Answer 1

$stmt = db::getInstance(); 
$query = $stmt->prepare("CALL delete(?)"); 
$query->bindParam(2122, $return_value, PDO::PARAM_STR, 4000); 
$query->execute();

You need to be calling PDOStatment::bindParam. The prepare method returns the PDOStatment Object. The PHP PDO/PDOStatment manuals should help.
