I am a web designer on a hard(very, very hard) quest to make a similar site to Amazon/ebay.
I have been looking it up and i realise how hard it is going to be, but one way or another i have to do it.
I will be making it using PHP, MySQL. I am pretty good with HTML and CSS. I have little experience with PHP.
Right now i am reading and applying methods from - Build Your Own Database Driven Web Site Using PHP & MySQL
I aim to make an ecommerce site first and then carry on with that.
I am not expecting all of my answers from one source.
However, i am willing to bring all the bits and pieces together and make this happen.
