php sessions

[Pedro_Sim__es]

Hello, I'm having some problems with php sessions when I start 2 sessions in the same php file.
I've been using this sample code to test:

session_name("sessao1");
session_start();

if(!isset($SESSION["param1"])){
$SESSION["param1"] = "logged";

echo "<p>abri a sessão 1 <a href=\"logout_sess1.php\">Logout</a></p>";

}
else{
echo "<p>Sessão 1 aberta <a href=\"logout_sess1.php\">Logout</a></p>";
}

session_name("sessao2");
session_start();

if(!isset($SESSION["param2"])){
$SESSION["param2"] = "logged";

echo "<p>abri a sessão 2 <a href=\"logout_sess2.php\">Logout</a></p>
		<p><a href=\"sessao1.php\">Sessão 1</a></p>";

}
else{
echo "<p>Sessão 2 aberta <a href=\"logout_sess2.php\">Logout</a></p>
<p><a href=\"sessao1.php\">Sessão 1</a></p>";
}

And I have 2 php files, one for the logout of "sessao1" and another for the logout of "sessao2". The problem is when I do logout of the "sessao1", the "sessao2" is also closed, and when I do logout of the "sessao2" none of them are closed. :mad:

Any sugestion?

Here's the code of the logout:

session_name("sessao1");
session_start();

$_SESSION["param1"] = null;
session_destroy();

header("Location:sessao1.php");

the logout of the "sessao2" is the same with the exception of the 1 turns 2.

sessions like their predecessor cookies, cannot be started before ANY output is sent to the browser

Not only that it's not supposed to be declared before any output but I don't think you can have two distinct sessions declared in the same instance. Give it a try and have a look at your sessions temp directory - there will only be one session file there - which is your fist session - "sessao1"

You can only have one session per session; why would you want two?
