How to echo a quotation mark?

Hello,

In my save code I need the level's path to be written in to a file saved but the problem is I can't get it to print out the necessary " (Quotation) marks. It thinks it's syntax and that it shouldn't print it. Is there something I can write to make it say:

$SaveDir = "game/data/levels/Level2.t2d";

instead of

$SaveDir = game/data/levels/Level2.t2d;

?

Thanks a lot!
