Convert hex to ascii characters

Question

Is it possible to represent a sequence of hex characters (0-9A-F) with a sequence of 0-9a-zA-Z characters, so the the result sequence is smaller and can be decoded?

Answer 1

I think you're looking for this:

function hex2str($hex) {
    $str = '';
    for($i=0;$i
