What are the common errors or warnings encountered when using call_user_func_array with bind_result in PHP?

When using `call_user_func_array` with `bind_result` in PHP, a common error is "Cannot pass parameter 2 by reference." This error occurs because `bind_result` expects its arguments to be passed by reference, but `call_user_func_array` does not support passing arguments by reference. To solve this issue, you can use `bind_param` instead of `bind_result`. 

// Incorrect usage with call_user_func_array and bind_result
$stmt = $mysqli->prepare("SELECT id, name FROM users WHERE id = ?");
$stmt->bind_param("i", $id);

$parameters = array($stmt, "id", "name");
call_user_func_array(array($stmt, 'bind_result'), $parameters);

// Correct usage with bind_param
$stmt = $mysqli->prepare("SELECT id, name FROM users WHERE id = ?");
$stmt->bind_param("i", $id);

$stmt->execute();
$stmt->bind_result($id, $name);
$stmt->fetch();
