Description Author

This class can encode and decode numbers in any base up to 65, where PHP base_convert only works up to 36.

It can take a given number and convert it into a text string made of characters that represent that number in any number base.

The class can also take a previously encoded number as text string and retrieve the original number value.

Create a base numbering system to meet your needs.

Designed to create short urls based on a decimal id number - the default charset contains the unreserved URL characters and is good up to base65.

Using AnyBase is simple. Simply, initialize an object with or without a charset and use it to encode or decode a number.

$b65 = new AnyBase();

$original = 1000000;

$encoded = $b65->encode($original); // '3FIE'

$decoded = $b65->decode($encoded); // 1000000
