How to print an echo statement before header

[Bannu]

Hi All,

I prepared a project where session starts while log in and will be log out by checking through the same session. When I log out from the page I kept header("locatio n:index.php"); so it redirects to the log in Home page as per my code. Well, now I would like to print a statement SUCCESSFULLY logged out along with the index page. Tried many ways and used ob_end_flush(); but unable to meet my requirement.

Otherwise it would be fine that the Content executes for few seconds and then it should redirect to the index page.

Can anyone help me out on this please..

You cant achive your requirements with your current method. there is no way you print something before sending header. If you were actually allowed to do so your browser would failed to read your data and create unknown response error. what you can do is create timer first echo that user has been logged out then after certain period call function in javascript to redirect page to other url just call the below code:
window.location =url;

Can you set a session variable when the log out command is sent, and display it in a portion of your index.php, or do you kill the session first?

if (isset($_SESSION['logged_out']) && $_SESSION['logged_out'] == true) {
    echo $message;
}

Otherwise, could you include something similar with a $_POST variable?

Thanks for the replies @Johny,jdstanko sky

if(!isset($_SESSION['aid']))
	{
		header("location:index.php");
		exit;
	}
	session_destroy();
	echo "Successfully logged out from Admin Page";
	
	?>

Finally I wrote the code as above.

After log out it dispelling the echo statement. When I refresh the page it is redirecting to the index page..

Is this right way?

this is not wrong, but you are looking for redirecting to your index page. thats why I was talking about timer

Probably the simplest answer is Johny's with a javascript timer. Try looking up javascript function setTimeout() to accomplish what you had originally asked.

a simple HTML redirect via <meta http-equiv="refresh" ...> works even with JavaScript turned off.
