If you had a constant named "somefile" or "php" and you use the second syntax, the constant would be interpolated/evaluated to the value of the constant.
Generally I always use single quoted strings unless there's some need for double-quoted strings (like if I want to embed a variable) so something like this can't happen.
BTW, I'm talking out my butt here, but it might be true. The advice is still sound, regardless.
