Please you can tell me how I save an array in database?

Thank you

You need to process the array to the format you want to save it, for example you can use the php implode function and generate a list of items with a separator like a comma ’ or a pipe |.

Thank you very much...
Finally I got it

You can also use serialize() + unserialize()
