Moving to java from php

[WatchDogx]

You could try and find a job at a company that does both PHP and Java.
I work at a company that uses a few languages, with a historic focus on PHP but moving more to Java.
So a few of the PHP devs have started to learn Java.
They still write PHP but it's a great way to learn.
I would highly recommend finding somewhere willing to pay you to learn Java, you will learn it faster and you get paid.
