As a base for a well rounded developer, I would say to pick C# or Java and Ruby or Python, and C or Go. Learn javascript. Avoid PHP, even if you're starving.
PHP has actually matured pretty well. Since the introduction of Composer and frameworks like Symfony 2, Zend Framework 2 and Doctrine 2, you can actually build very sophisticated software in PHP. However, for green field projects I personally wouldn't use it.
However, having said that, there are still plenty of guns lingers out there copying and pasting crap from PHPClasses.
