As years pass by, you will want to go more into Java. Why? You will be older, probably with family, you will have different priorities and will want to have a better work/private life balance. All of that normally comes while working in bigger companies, with better organized and structured teams/work, with bigger budgets and projects. And in such companies, Java is the way to go.
While you're still younger, and with some more spare time on your hands, being able to work anytime you like - day or night, PHP is a great and interesting thing to pursuit. And there are also very big and interesting projects with it, just not as big and not as much as with Java.
Whatever you do - keep learning all the time and follow good programming practice. It will help you in any language tomorrow.
