Well, we have used PHP extensively until now. We have gotten more disciplined in designing code, compartmentalizing it into classes, documenting the code etc.

However, I recently read an article on YC about how many startups go through a phase debating about which language an application should be built on. We did not give this much thought as we saw a few prominent websites like facebook use PHP and we thought PHP seemed to be a pretty scalable language. Plus, with support for OOP (as of PHP 5), PHP seemed to be a pretty good choice.

I am interested in evaluating if we made the right decision
