What are some alternative methods, such as using sessions or hidden fields, to manage a delay before redirection in PHP?

When managing a delay before redirection in PHP, one alternative method is to use sessions to store a timestamp when the delay started and then check if the delay has passed before redirecting. Another method is to use hidden form fields to pass the delay time to the redirected page and use JavaScript to trigger the redirection after the specified delay. 

// Using sessions to manage delay before redirection
session_start();
$_SESSION['redirect_time'] = time() + 5; // 5 seconds delay
// Check if delay has passed
if (time() >= $_SESSION['redirect_time']) {
    header('Location: new_page.php');
    exit();
}

// Using hidden form fields to manage delay before redirection
<form action="redirect_page.php" method="post">
    <input type="hidden" name="delay" value="5"> <!-- 5 seconds delay -->
    <button type="submit">Redirect</button>
</form>

// In redirect_page.php
$delay = $_POST['delay'];
echo "<script>setTimeout(function(){ window.location.href = 'new_page.php'; }, $delay * 1000);</script>";
