how to begin my own PHP-based shopping cart?

I will be doing my first e-commerce job in a couple of months and need pointing in the direction of some resources.

Does anyone know of a good source of shopping cart related PHP scripts or better still an entire PHP shopping cart solution. Online payment is not an issue as the company will be sending invoices through the post.

Also a pointer any info on usability and e-commerce solutions would be helpful.

Thx

Hi,

There is a long list of E-Commerce applications out there, it really depends on what you want to do, but I would encourage you to use something which already exists and maybe adapt it to your needs. Why not use/modify HikaShop for your needs, for example ?
