uniqid() is the normal way to generate a unique string?
Or is it better to generate a random string and then hash it?
in someone else's code, I mostly meet the second method.

Yes, it's not a bad way.
uniqid() is one function,
and hash + random string is at least 2.
Don't over complicate things

If you need a string as an ID, then I can advise a compatible RFC 4122solution https://github.com/ramsey/uuid
