I would start with something like this:

    $con =  new PDO( "mysql:host=".$dbHost.";"."dbname=".$dbName, $dbUsername, $dbUserPassword); 
    $con->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $sql = "DELETE FROM `table` WHERE id = ?";        
    $q = $con->prepare($sql);

    $response = $q->execute(array($id));
