The problem is that `bindparam` binds by reference, and `foreach` reuses the same variable for `$value`, with the same reference, in the loop? Then the solution could be to use `&$value` instead. Untested: foreach( $bind_params as $key => &$value ){ $statement->bindParam($key, $value); } unset($value); BTW The fact that you need to manually break the connection between the loop variable and the array item value using `unset` is a bug, in my opinion.
