A Clean Bijective Base Converter for PHP
This package is a bijective shortener which shortens your unique integer identifier(like a mysql auto increment key) to a unique short string, the strategy simply makes a number with a longer base.
You can set the characters which you want to be included into the shortened string, by default a random string is set. You should note that this is not an encrypting solution it's just an encoding solution like base_64 but in a bigger base, but by making a random sort of allowed characters you can gaurantee that it is impossible to guess a long number given a shortened string.
