If anyone is decent with PHP, how would I convert this stock into PHP?

I'm using it for a simple online user account system, I am not concerned with security, I would just like to know how to do it.

stock num_hash(buf[])//Dutils.inc
 {
    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;
 }

PHP код:



function num_hash($buf)

{

  $length = strlen($buf);

  $s1 = 1;

  $s2 = 0;

  

  for ($n=0;$n<$length;$n++) {

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

       $s2 = ($s2 + $s1) % 65521;

  }

  return ($s2 << 16) + $s1;

}

P.S. I don't test this =)

I tired this as a simple php login, and it didn't work. Either I am hashing it wrong with the function you have me, or the hash didn't work.

Anyone know what I did wrong:

<?php
$password = '329384925';//This is the result from my script (later I will have it get this password from the ini- implemented now for testing).
function num_hash($buf) 
{ 
  $length = strlen($buf); 
  $s1 = 1; 
  $s2 = 0; 
   
  for ($n=0;$n<$length;$n++) { 
       $s1 = ($s1 + $buf[$n]) % 65521; 
       $s2 = ($s2 + $s1) % 65521; 
  } 
  return ($s2 << 16) + $s1; 
}  


//session_start();
if (!isset($_SESSION['loggedIn'])) {
    $_SESSION['loggedIn'] = false;
}

if (isset($_POST['password'])) 
{
    if (num_hash($_POST['password']) == $password) 
    {
        $_SESSION['loggedIn'] = true;
    }
    else 
    {
        die ('Incorrect password');//Currently returns this when I enter the correct password.
    }
} 

if (!$_SESSION['loggedIn']): ?>

<html><head><title>Login</title></head>

<?php
exit();
endif;
?>
