About the note from Cybertinus :
The following test doesn't work, the code following is always executed :
if(!session_id())
{
// Always executed even if there's already an opened session
}
session_id() returns an empty string if there is no current session, so to test if a session already
exists, it's better to write this :
if(session_id() == "")
{
session_start();
}
else
{
// Anything you want
}
