Question

I am creating a login module in php. I am using session variables for that.
On the top of the file, I write
session_start();

Then when my login password is authenticated, I write
$_SESSION["username"] = $_POST["userid"]

now do I need to do something else as well to ensure that the session that got started sustains?? because as soon as it logs in, it logs out automatically? does it mean the session expires as soon as I log in?? In that case what should I do to make the session sustain??

Answer 1

Put session_start(); at the top of page where you will use the session variables.
And be sure you don’t unset session in you login script.
