If your goal is to get a job locally, and locally people hire for PHP, and you want to learn PHP: Then just learn a little PHP.

Learning another programming language...any language...will make you a better programmer. Even if you never use it.

I have still much time so I can learn anything.

Yes. You have decades. And they will all be decades as an adult. For the sake of example, I will pretend you are 22 and that people become adults at 18. So you have four years of adult experience. Sure you have learned a lot in your four years of adult experience.

But it is but four years out of the forty four you will have in four decades. And those four years are all beginner experience. A lot will change. Optimize for change. Forty years ago, a person in your position would be looking at COBOL, Pascal, C, Fortran, ADA, and Lisp (not Common Lisp, that didn't happen until later (and C was still K&R, not ANSI)).

Don't micro optimize. Learn how to learn. Good luck.
