Having programmed in c#, java, js and a bit of c++.
Two things you'll get from it:
1 - Quicker processing of the math
2 - Maybe a touch of pattern recognition.
Thats about it.
The problem with being a programmer and a poker player is this. Programmers are very logical, structured and generally, play by the numbers. Where logic will fail is when you meet a player that is creative in their play, it'll end up confusing most that are heavy into programming - at least in my exp. I had to shake off that strict thinking to be able to play among higher skilled players. It cost me a lot of money to realize that. Unless you learned to "program" in php and are self taught that is, in that case, you're probably already pretty creative and should be just fine.
