Start with html, then css, then php. It's taken me 8 years since I started web design but I'm fluent in a lot of languages now...
xhtml, css, javascript, php, vb.net, bash, c, c#, actionscript, xml
Basically once you know one it's pretty easy to pick up the syntaxes and apply your knowledge to other languages. The best part about coding is Google is the key to learn, instead of posting in forums everytime you have an error just search google and there's a 95% someone else will have already come across that issue. If not start a thread and you'll add useful knowledge for the next person that has the same question.
