How do you unserialize data in MySQL?
The best approach is to have normalized table structure (different fields or tables). The next approach is to save data as a delimited string (e.g.: 0,US,1,19 ). Then you can use MySQL’s SUBSTRING() or to use standard serialization mechanisms like JSON encode. thats right but the value is not inserted by external app.
How is serialized data inserted into database?
