MDCode Posted January 13, 2013 Share Posted January 13, 2013 I don't see anywhere that you are setting the session differently. It will always be what you set it to be, no matter what. And you are echoing your session outside of your if(isset()) { ($_POST['submit'] does nothing btw). So on every page load of course it's going to display before you click submit Quote Link to comment https://forums.phpfreaks.com/topic/273094-basic-session-doubt-php-beginners/#findComment-1405342 Share on other sites More sharing options...

You are doing that. However, I think what you fail to realize is that in the script you provided, once you set the session, it will always echo "same". Once you set a session, it is set for the "session" - which is a configurable time period, but by default it means it will be set for the duration of your browsing visit. If you close your browser, it will clear the session. If this is not the behavior you were looking for, you need to just use a simple variable instead. A variable will only exist for the duration of the script.
