How to make php grid, what to use?

Question

PHP

I form a php form for ordering goods in the admin panel.
5 fields, but how many lines will be in the end - it's not clear.
What tool should be used to form dynamic lines in the order, and then send this information to the database.
I would be glad to help and links)
I googled, but I didn’t find clear answers, or I read it wrong.

Answer 1

If you don't need to search by custom data, serialize the array with data and put a string in the base. If you need a lookup or other processing that cannot be done with serialized data, use the nosql solution.

Answer 2

I did not understand your answer a little .. I
assume the following:
there are fields -
No. | name | price | number
and for example the button to add another line.
and form two orders -
a)
1 | title1 | price1 | quantity
2 | title2 | price2 | quantity
3 | title3 | price3 | number
b)
1 | title1 | price1 | quantity
2 | title2 | price2 | quantity
3 | title3 | price3 | quantity
4 | title4| price4 | quantity
5 | title5 | price5 | number
all fields will be filled by hand, but the number of lines is dynamic. But what to use, so that you can create a dynamic order in the lines, and fill them in the database.
