Mysqli Prepared Statements Error

问题

I'm little bit confused with first use of mysqli dynamic parameter binding. My query is

 UPDATE tb_hotel SET hotel_name = ?, hotel_overview = ?, hotel_active = ?,
 hotel_location_description = ?, hotel_location_gmap = ?, hotel_cm_mapping_id = ?
 WHERE hotel_id = ?

When I dump the array which I pass to call_user_func_array is

  array (size=8)
  0 => string 'ssisssi' (length=7)
  1 => &string 'sdfsfdsf' (length=8)
  2 => &string 'sdfdsf' (length=6)
  3 => &int 0
  4 => &string 'dsfdsfds' (length=8)
  5 => &string 'fsdfsdf' (length=7)
  6 => &string 'fsdfdsfsdf' (length=10)
  7 => &int 17

Then I pass them to call_user_func_array like bellow.

call_user_func_array(array($stmt, 'bind_param'), $param_array_bind);

I'm getting the error "Warning: mysqli_stmt::bind_param(): Number of elements in type definition string doesn't match number of bind variables in"

Can anyone shed some light on me.

You're putting 7 fields in your MySQL code and your array has 8 elements. This is the problem.
