If the function doesn't exist, this is a messy but effective way of doing it:
<?
echo bencode("Gabriel Malca");
// R2FicmllbCBNYWxjYQ==
function bencode($string='') {
$binval = convert_binary_str($string);
$final = "";
$start = 0;
while ($start < strlen($binval)) {
if (strlen(substr($binval,$start)) < 6)
$binval .= str_repeat("0",6-strlen(substr($binval,$start)));
$tmp = bindec(substr($binval,$start,6));
if ($tmp < 26)
$final .= chr($tmp+65);
elseif ($tmp > 25 && $tmp < 52)
$final .= chr($tmp+71);
elseif ($tmp == 62)
$final .= "+";
elseif ($tmp == 63)
$final .= "/";
elseif (!$tmp)
$final .= "A";
else
$final .= chr($tmp-4);
$start += 6;
}
if (strlen($final)%4>0)
$final .= str_repeat("=",4-strlen($final)%4);
return $final;
}
function convert_binary_str($string) {
if (strlen($string)<=0) return;
$tmp = decbin(ord($string[0]));
$tmp = str_repeat("0",8-strlen($tmp)).$tmp;
return $tmp.convert_binary_str(substr($string,1));
}
?>
