MySQL中的MySQLi轉換

Question

while ($field = mysqli_fetch_field($query->result_id)) { 
      // Most versions of MySQL store timestamp as a string 
      $is_int[$i] = (in_array(strtolower(mysqli_field_type($query->result_id, $i)), array('tinyint', 'smallint', 'mediumint', 'int', 'bigint'), //, 'timestamp'), 
       true)) ? true : false; 

      // Create a string of field names 
      $field_str .= '`' . $field->name . '`, '; 
      $i++; 
     } 

致命錯誤：Call to undefined function mysqli_field_type()
