I would like a function or some source code that can uudecode a string. This can be accomplished in Perl easily with $decoded = unpack("u", $encoded); Encoding data with: $encoded = pack("u", org_string);

I have found that PHP has a pack function but did not include a "u" (uudecode) option. I found an example that supposedly works, but after testing it, it does not decode properly. Here is the example:

function uudecode($encode)
{
    $b64chars="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklm nopqrstuvwxyz0123456789+/";

    $encode = preg_replace("/^./m","",$encode);
    $encode = preg_replace("/\n/m","",$encode);
    for($i=0; $i<strlen($encode); $i++)
    {
     if ($encode[$i] == '`')
     $encode[$i] = ' ';
     $encode[$i] = $b64chars[ord($encode[$i])-32];
    }
while(strlen($encode) % 4)
$encode .= "=";

return ($encode);
}

I found a good site that explains in depth how uuencoding works, it is at http://www.drbob42.com/books/uucode.htm
There is a Pascal example that I have not yet tried converting into PHP.

The character set used for decoding was different from the example, here are the characters from the web site.
$b64chars="`!\"#$%&'()*+,-./0123456789:;<=>@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_";

I tried substituting the characters into the function and it also did not work.
