Hey Scott,

I think random_bytes() and random_int() are great; they provide a
much-needed building block in PHP 7.0. However, I do worry a bit that
the most common use for random_int() (generating a random string of a
fixed length with a given character set) will be reinvented over and
over again, and rarely consistently.
I would propose a random_str() function that behaves similar to this
userland snippet: http://stackoverflow.com/a/32870871/2224584
Generating random strings of characters is difficult, yeah, so this
seems useful. But I do wonder if this function is the right approach.
What if you have some other source of bytes and want to also produce a
sequence of characters matching some format?
What I think might be better is some bytes-to-arbitrary base conversion
function, one which lets you specify the character set to use. Then you
could use that with random_bytes(), but also with something else,
perhaps a public key? This way we don't have to duplicate the same
functionality somewhere else.
Thanks!
