do I always have to do die() after an or when calling a function?
or is it just a
convention?
all the examples I saw had die() after the or.
thanks

No you don't - it's used to prevent further code from running if an important function fails. For example if you can't connect to a database you wouldn't then want to try and query it because you'll just get loads of errors.
You don't see it used much except when it comes to database functions.

Yes,

but instead of stopping everything you can instead return something
that indicates failure and catch it.
I always thought that die() is too harsh.

Of course you can. Or die() isn't always appropriate.
