im not to sure on how to make this, ive installed apache, mysql and php and all work ok, would these be the best programs to use for what i want?
could someone give me advice on how i would make this and terminology about the type of things i need to make:

users can add there product "productid, price, size, details"

though they have to pay before they can add something

once added they can make changes to details, description, price etc

can browse everything for sale and sort by price, size etc
