I don't think it's the players who demand this stuff. The billionaire owners are the ones protecting their investment by trying to keep their players marketable. Good team owners make way more than they spend in player salaries.
I want to learn a good web development language. I've been looking around on the internet for good ones to learn, but everyone says something different. I'm kinda leaning toward PHP and MySQL. I have basic knowledge of C++, Java, and HTML.
Is PHP a good route to go? I want to learn something useful and not overly complex.
