[RESOLVED] session question

182x

Sorry for all the newbie questions today,

I have been using session variables to get the user id when they login so that they are once logged in they can be validated based on their id. So if they didn't log in they would be redirected to the login page.

However if another users logs on at the same time will this overwite that session variable or how is that managed?

the code ii used is below:


		$getId = "SELECT user FROM u WHERE u = '$u' AND p = '$p'";
		$qu = mysql_query($getId, $link_id);

		if (mysql_num_rows($qu) > 0 )
			{
				$st= mysql_fetch_assoc($qu);
				$_SESSION ["uid"] = $storeAdmin["uid"];
				header("location:home.php");
				exit();
			}
			break;

Each user has their own, unique session ID and a separate session file associated with that ID. The ID is exchanged between the client and the server by a session cookie. The result is that the $_SESSION values (if any) are separate for each user.

Thanks again for the reply, does that mean thats its all handeled by the server or would any additional code be required?

The [man]session_start/man function takes care of all the details. Used by itself, it uses the current default settings for how session IDs and session data are handled.
