Directly with update, usage

$m =m (' Tbale ');  Table name $data[' id ']=98;   The first value must be the updated condition, that is, the table's primary key, that is, the condition to be updated $data[' type ']= ' the value to update ';  After the first condition, the value of the sub-segment to be modified is then $data[' type2 ']= ' 2 to update the value '; $data [' Type3 ']= ' 3 value to be updated '; $m->save ($data);  Finally,   you can update it with the Save method. After the update, a value is returned, which you can print out to determine.
