/**
 * This is an example of a practical encoder and decoder for base-62 data in PHP
 * It differs from the majority of examples in that it's fast enough for moderate data sizes, unlike multiprecision converters
 * To be practical, base-62 encoding needs to use internal chunking and padding because base-62 does not fit exactly into any integral number of bits
 * This means the output is not quite compatible with multiprecision conversions,
 * but the encoded data retains all the desirable properties of base-62, so (unlike any base-64 encoding) it's URL, DNS, email address and pathname safe
