You can use substr:

substr($str, -1)

This returns the last byte/character in a single-byte string. See also the multi-byte string variant mb_substr.

But if you just want to remove any trailing slashes, rtrim is probably the best solution.

And since you’re working with URLs, you might also take a look at parse_url to parse URLs as a trailing slash does not need to be part of the URL path.
