I have created this function in php which gives me the correct value for
33181 ("nYEAAA==") but I would like for another pair of eyes (or 20) to see
if this is solid and if it can be simplified.
function MgBase64_encode($value){
$key="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=";
$dhv = dechex($value);
$grp = (strlen($dhv) / 2);
$arr = array();
for($i=0;$i<$grp;$i++){
$arr[$i] = substr($dhv,($i * 2),2);
}
$arr = array_reverse($arr);
$bvl = decbin(hexdec(join("",$arr)));
$chk = (strlen($bvl) % 6);
if($chk > 0){ $bvl = str_pad($bvl,(strlen($bvl) + (6 - $chk)),'0'); }
$grp = (strlen($bvl) / 6);
$arr = array();
for($i=0;$i<$grp;$i++){
$arr[$i] = substr($key,bindec(substr($bvl,($i * 6),6)),1);
}
return str_pad(join("",$arr),6,'A') . "==";
}
