How can PHP developers output values on a different page after a countdown has completed and redirected?

To output values on a different page after a countdown has completed and redirected, you can use sessions to store the values and then retrieve them on the redirected page. Set the values in the session before redirecting and then access them on the new page to display the output. 

// Page 1: Set values in session and redirect after countdown
session_start();
$_SESSION['output_value'] = "Hello, World!";
header("Refresh: 5; URL=page2.php"); // Redirect after 5 seconds

// Page 2: Retrieve values from session and display output
session_start();
if(isset($_SESSION['output_value'])){
    echo $_SESSION['output_value'];
} else {
    echo "No output value found.";
}
