title: Shorten integer IDs in PHP
body: <p>I am working on a site that requires people to type the ID of a user after the URL to get to the page they need. E.g. www.mysite.com/235163 where 235163 is the ID number of the profile. But is there a way to shorten numbers by introducing alpha numeric characters into the ID number so 235163 may be shortened to 1d or something a long that lines as obviously, i'm merely trying to minimize mistakes from the user inputting long numbers. Can anyone help? </p>
