Functii si directive deprecated in php 5.3.x

Deprecated: Function session_register() is deprecated in ….
Am gasit o ‘solutie’ la aceasta problema,zic solutie deoarece acea eroare nu mai apare
am inlocuit:

session_start();
session_register("login","pwrd","id");
cu
session_start();
$_SESSION['login'] = "login";
$_SESSION['pwrd'] = "pwrd";
$_SESSION['id'] = "id";
insa in continuare nu reusesc sa ma loghez in admin panel si nici inregistrarea unui membru nu functioneaza,desi in baza de date exista un user cu toate privilegiile,in plus am creat manual un user normal

login.php

<?
unset($login,$pwrd,$id);
session_start();
$_SESSION['login'] = "login";
$_SESSION['pwrd'] = "pwrd";
$_SESSION['id'] = "id";

if(@$logout==1){
session_destroy();
header("Location: ".$PHP_SELF);
}

require('config_inc.php');
require('error_inc.php');


//require('error_inc.php');
//require('config_inc.php');


if(auth($login,$pwrd)!=0){
header("Location: $path/user_menu.php");
}

if($REQUEST_METHOD=="POST"){
if(isset($lo)){
$log=htmlspecialchars($log);
$passwrd=htmlspecialchars($passwrd);

$au=auth($log,$passwrd);
if($au>0){
$login=$log;
$pwrd=$passwrd;
$id=$au;
header("Location: user_menu.php?PHPSESSID=".$PHPSESSID);
}else{
require('header_inc.php');
print "<p>".$err[1]."</p>";
}
}
}else{
require('header_inc.php');
