[PHP-DB] Password decryption

[Nasreen Laghari]

Hi,
 
I'm junior in PHP and stuck on Encryption. 
 
I have encrypted password using SQL :
 
$query = "insert into user (userid,password,) values 
('$username',Password('$pass'));";
 
Which is working perfect. Now I'm working on Login page where I have to compare 
passwords.. As password in database is encrypted so I need to decrypt it back 
for compression. I have tried the flowing but not working.
 
 if ($pwd != Password("$info['password']")) 
  {
   echo("-");
   //header("Location: abuse.php");
  }
 
and 
 
 if ($pwd != $info(Password("['password']")) 
  {
   echo("-");
   //header("Location: abuse.php");
  }
 
Could any one please help..

Thank you

Re: [PHP-DB] independent session data for multiple browser windows

Greetings,

I have a nearly-completed accounts/billing database using PHP and 
MySQL, and was just informed that users will want to access the 
database via multiple windows in one browser on the same machine, so 
I'm looking for a way to have each browser window have its own set of 
session data.


I was initially using cookies, so I switched to propagating the 
session name via the URL, and had each window using a unique session 
name, but the DATA from each named session was written to the same 
file on disk (/private/var/tmp/whatever).


I noticed that the session data file name included the session id, so 
I tried propagating the session id in the URL, and setting the session 
id right before session_start() -- that resulted in two data files on 
disk, but one session would occasionally write to the other session's 
data file. At this point, this is the code I'm trying:


if (!array_key_exists('SESSION_ID', $_REQUEST)) {
$_REQUEST['SESSION_ID'] = 'SESS'.uniqid('');
}
session_name($_REQUEST['SESSION_ID']);
session_id($_REQUEST['SESSION_ID']);
session_start();
output_add_rewrite_var('SESSION_ID',$_REQUEST['SESSION_ID']);

In php.ini, I now have:
session.use_cookies = 0
session.use_only_cookies = 0
session.auto_start = 0

Also, I'm on Mac OS X Tiger, and everyone's using Safari. PHP 5.0.24a, 
MySQL 4.1.22


Any suggestions on how to have unique session data for multiple 
windows in the same browser on the same machine? Seems like it must be 
doable, but I haven't figured it out yet. Thanks to whomever can help.

As far as I know, the only way for this to work reliably is if your 
users can manually choose to open a new "session" in a new window/tab. 
Is this the way you want it to work? Because you can't reliably stop 
them from having the same session in multiple windows if they would so 
choose.


On the other hand, why would you require multiple sessions if they are 
to work against the same database? Will they be using different user 
accounts to access it simultaneously, or some administration user with 
authorization proxy to use regular accounts?


What kind of information stored in the session would require them to use 
different sessions for different tabs? If you give us a hint, we might 
be better able to help.
