Are there alternative methods to achieve a delayed redirection in PHP besides using header() function?

The issue with using the header() function for delayed redirection in PHP is that it must be called before any output is sent to the browser. An alternative method to achieve delayed redirection is by using JavaScript's setTimeout() function to delay the redirect after a certain amount of time. 

<?php
// Start output buffering
ob_start();

// Set the delay time in milliseconds
$delay = 3000; // 3 seconds

// Output a message or perform any necessary operations
echo "Redirecting in 3 seconds...";

// Flush the output buffer
ob_flush();
flush();

// Delay the redirect using JavaScript
echo "<script>setTimeout(function() {
    window.location.href = 'new_page.php';
}, $delay);</script>";
