help with session

[osusano]

i am new with session havent tried it b4 and im currently doing a project where in i need to use a session but since i tried the code

session_start();
$SESSION['username'] = $username;
$SESSION['password'] = $password;

it does give me an error like this.

Warning: session_start(): open(/tmp\sess_796cf477445acc224c88e2633148b8a5, O_RDWR) failed: No such file or directory (2) in c:\webserver\home\userspage.php on line 18

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at c:\webserver\home\radio\userspage.php:18) in c:\webserver\home\radio\userspage.php on line 18

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at c:\webserver\home\userspage.php:18) in c:\webserver\home\userspage.php on line 18

so basically from my login page i go directly to userspage.php and from the top of the page i have a query and check if the username and password is correct then if it correct i include the code

session_start();
$SESSION['username'] = $username;
$SESSION['password'] = $password;

thats why it give an error and i dont know how to fix it can someone tell me pls?

thank you in advance

You have wrong session save path in your php.ini configuration.

First, create a temp dir(or tmp whatever you like). eg C:\tmp.
Now change the session save path line in php.ini to that(the default is "/tmp", thats why it cannot save the session data).

Remember to give the dir proper attributes so php can write to that directory

ok i have tried it and my session already up and running i tried using this 1

session_start();
$SESSION['username'] = $username;
$SESSION['password'] = $password;
$_SESSION['name'] = $name;

now how can u eliminate the 1 single session store?

like i want to remove the session named "name"

and how can i close my session if the person log off

There is extensive coverage of PHP's session-handling functions in its manual.

$SESSION['name']=null; or unset($SESSION['name']); (just like any array)

session_unset(); session_destroy();
