What does "$" represent when programming? [closed]
I have noticed that questions and answers often have lines of code that begin with "$". I have personally never used this syntax when coding. I have seen it most commonly when looking at PHP code snippits(may be irrelevant).
Is this a convention? Is it an abbreviation used in particular languages? Which language(s) is this used in?
Any information would be very helpful!
