I used to do uudecode as a C module, but I've discovered a really fast way
to do it in PHP. Here it is:
function uudecode($encode) {
$b64chars="ABCDEFGHIJKLMNOPQRSTUVWXYZ\
abcdefghijklmnopqrstuvwxyz0123456789+/";
$encode = preg_replace("/^./m","",$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)
$encode .= "=";
return
base64_decode($encode);
}
This is the PHP equivalent to perl's
unpack("u",___). That is, you need to strip the 'begin' and
'end' lines from the typical uuencoded file.
