Hello,

I have a problem with DUDB from dracoblua. I want udb_hash in php, but returns me to a different value (excuse me for the translation [****** translator]). I got it as follows:

Код:

function _udbhash( $pass )
{
  $length = strlen($pass);
  $s1 = 1;
  $s2 = 0;
  
  for($i=0; $i<$length; $i++)
  {
   $s1 = ($s1 + $pass[$i]) % 65521;
   $s2 = ($s2 + $s1)    % 65521;
  }
  return ($s2 << 16) + $s1;  
}

on dudb.inc SAMP:

Код:

stock udb_hash(buf[]) {
	new length=strlen(buf);
  new s1 = 1;
  new s2 = 0;
  new n;
  for (n=0; n<length; n++)
  {
    s1 = (s1 + buf[n]) % 65521;
    s2 = (s2 + s1)   % 65521;
  }
  return (s2 << 16) + s1;
}

I have the same problem. The thing is, in PHP forum peolple won't understand PAWN and send us to PAWN forum and vice versa. So if anyone could just explain these two lines:

Код:

$s1 = ($s1 + $buf[$n]) % 65521;
$s2 = ($s2 + $s1)   % 65521;

(i don't know what % does) and maybe I'd be able to script that in PHP.

Also I think the problem may be "<<" which in PAWNO is for power while in PHP might be something else...

OK, thanks to my brother, we have the solution. Hope it helps:

Код:

function udb_hash($pass)
	{
		$length = strlen($pass);
	  $s1 = 1;
	  $s2 = 0;
	  
	  for($i=0; $i<$length; $i++)
	  {
	   $s1 = ($s1 + ord($pass[$i])) % 65521;
	   $s2 = ($s2 + $s1)    % 65521;
	  }
	  $wy= ($s2 << 16) + $s1;
		return $wy;
	}

% = remainder by division.

'In computing, the modulo operation finds the remainder of division of one number by another.'
