I am totally new to php. I know nothing. So I need some inputs from you guys. I make static websites with HTML and CSS. I got a customer want to make web-shop with shopping cart, SSL, and dynamic pages. She has about 20 products and she is planning to increase up to 100 products. Well, what she meant by a dynamic page is that she wants to have an index page which changes products displays according to customers buying behaviour or web history. Or it just needs to change products displays each time when a customer go to the index page. I don't know where to start. So I bought a PHP and mySQL book and started reading. My question is that what is the best way to create this website. Where can I find the resources(books, websites etc) to create 1) this kind of dynamic website, 2) best shopping cart for PHP and Mysql. I will appreciate your inputs here. I must start somewhere. Oh my.... I know I've got a lot to do.... :'(
