I want to iterate through all 5 character combinations of 0-9, a-z.
I worked it at to be around 52 millions combinations. How can I programatically iterate through all the possibilities in PHP? - like counting up or something?

A:
Use base_convert($n, 10, 36) counting from 0 to 36**5-1, and pad with zeroes via sprintf().

there's no need to pre-calculate 36^5, just `while($x != 'zzzzz')...`

Do note that `base_convert()` returns a string, therefore you should use the `%s` format specifier.

I tried to provide an answer, but kept getting stuck with it.
So I'll post maybe the only useful portion. To get a list of all those chars easily, the following should do the trick.
$pool = range(0, 9) + range('a', 'z');
