blhack is right. PHP has undergone a lot of changes since the 90s, but it&#x27;s still the tops when it comes to open source languages that companies are looking for...at least in Philly. It looked like everything was going to Ruby a few years back, but PHP is holding steady. If you have the time, I&#x27;d learn full stack JS - but you can&#x27;t go wrong with PHP.
