[SOLVED] Where does session data get stored?

[forumnz]

On the server?

[PFMaBiSmAd]

By default, it gets saved in files where the session.save_path parameter points to - session.save_path = "/tmp"

[forumnz]

If i am using an FTP can I find it on there?

Delends on how much access you have to the host machine. If it's just shared hosting, you probably don't have access to that folder.

Im trying to get a text to say one thing if the session is 'set' and another if its not...

[kenrbnsn]

Use the [url=http://www.php.net/isset]isset()[/url] function.
Example:
[code]<?php
session_start();
if (isset($_SESSION['something'])) {
//
//  do one thing
//
} else {
//
// do something else
//
}
?>[/code]

Thanks,

I had this, should it work?

[code]<?php

session_start();


if (!$_SESSION['username'])
{
echo('Log In');
} else
{
echo('Log Out');
}
?>[/code]

[forumnz]

Help?

The code you posted will work (it does generate a Notice level error if the session variable does not exist - which is why kenrbnsn gave code that used the isset(...) function.)

When you tested it, what does it do?

[Orio]

Use the isset() function:

[code]<?php

session_start();
if (!isset($_SESSION['username']))
{
echo('Log In');
}else{
echo('Log Out');
}

?>[/code]

Orio.

[kenrbnsn]

Did you try it?  The quickest way to determine if code is going to work is to actually try it, not ask on a forum.

Yes I have tried it...

It always says "Login" - even if im logged in.

[PFMaBiSmAd]

Either sessions are not working or the session variable by that name is not being set. Add the following line of code after your opening <?php tag -
[code]error_reporting(E_ALL);[/code]
Also, post your code that starts the session and sets the session variable when you log in.

[forumnz]

Ok, I have managed to get it to say Logout when the user is logged in... but it comes up with this error..

[code]Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /usr/local/psa/home/vhosts/EXAMPLE/httpdocs/thing/area/index.php:7) in /usr/local/psa/home/vhosts/EXAMPLE/httpdocs/thing/area/index.php on line 53[/code]

You need to use that function before anything is output to the browser, preferably at the top of the script. Or use ob_start() and ob_end_flush() in your script.

oops it says

Log Out

[dcro2]

Yes, put session_start() before line 7 of your script. You can't send any headers after you start outputting to the browser.
