Wait-time before redirect in PHP

Question

This is my code on page1:

session_start();
if(isset($_SESSION[$login])){
    header("Refresh: 5; location:page2.php");
    echo "Welcome back!";
}

I thought this was the way to have a redirect on page2 AFTER 5 seconds of pause, in which the user can see the message "Welcome Back". Am I wrong?

The result of my code is a correct identification of the login, with the consequent showing of echo "Welcome Back", but the redirect isn't happening. I remain in page1 forever.

Where is the error?

ps: I made a search of similar threads, but I hadn't be able to solve the problem, so I'm posting here guys, thank you!

Answer 1

I believe you need to use url= rather than location:

header("Refresh: 5; url=page2.php");

Unfortunately, this is a non-standard way of doing redirection (and not a great one at that), so I have been unable to find any documentation for it.
