Can anyone send me to a good php session tutorial? I've googled but I haven't found any good ones...

I just want to restrict people from visiting pages unless they are logged in. As far as I know, this is what sessions are going to do for me.

I've done all the registration and login, except for starting and maintaning sessions, and using them to block a page unless being logged in.

Any help in this matter would be much appreciated (either info or a link to a nice tutorial/article/book).

Thanks in advance.

www.php.net - Sessions Online Manual. It has everything you need. Basicly you need to start/restart the session at the begin of every php file by using session_start(). After that you can freely do what ever you want with the $_SESSION super-global. There is one more little thing tho, you need to keep passing the session id to every request either via the URL parameters or cookies. Read up on the page i pasted above.

As for the implant-ation...there are a number of ways todo this, the easiest way would be to set a variable when a user logs in and checking it where needed then doing the appropriate action (either restrict him or display the page).

I am using the send cookie to users method.

Still not sure how to use the session id to my advantage... :\

The problem is I don't know how to reject a user that doesn't have a good session....

Any variable I create and pass will only exist if I pass it.

So if they try to get to the page without a session, the PHP will error with an unidentified variable, because it was not passed from a session.

//
// Login.php
if(LoginSuccessfull)
$_SESSION['loggedin'] = TRUE;
else
<do something else...>


//
// SomeProtectedFileThatNeedsALogin.php
if(!isset($_SESSION['loggedin']) || !$_SESSION['loggedin'])
<bitch to user>
else
<let him in>


Thats about it heh. You bypass that undefined error with calling isset() on it first.
