I have created a HTML & CSS site and want to now include a shopping cart to it.
I have looked at buying a ready made cart, but would really like to tackle it for myself and i am a really wanting to learn the more technical back end side to websites.
I am basically just asking if people would recommend PHP code for this or if not, anything else?
The site that it will be incorporated into is www.dinogrip.co.uk
Im ready for the next challenge!
I know that it’s perhaps slightly cheating but it may be a good way to learn, ZenCart is a very good and popular open-source e-commerce application built with PHP. Either that, or if may be worth investing in a beginners guide to PHP, many have a basic tutorial on integrating shopping carts. Hope this helps 
There are also lots of good free ready made carts. Right now I’m trying OpenCart, and so far I like it. And it’s made in PHP (like eCommerce, Magento, Zen Cart, and lots of others).
Of course, you can also write one yourself, that might be a challenge alright 
Are you familiar with programming, security and databases? If not than you will probably be better off with a open-source solution. That is unless this is for fun and you have all the time in the world. Than by all means build your own eCommerce solution.
