Hi fellow developers

I'm David. I want to learn more about programming.
My first question, is a kind of a bipartisan kind of question in that I can't ask in the php forum, nor in the java forum for fear of biased answers, and only being half on topic.
Well I want to build a website, ecommerce. I have done a bit of java, and I do have some php books here. I was learning java webside programming the last two weeks and then some googling on the web discovered that php is all the rage now. 75% of websites, 50% more job ads for php, and some search results even omit java programming when talking about web programming. Another forum didn't even have a java section in the server-side programming section.

So should I be considering doing php instead of java in 2013?

David.
