What are the considerations when using JavaScript for redirection in PHP?

When using JavaScript for redirection in PHP, it's important to consider that JavaScript runs on the client-side, so the redirection will only occur after the PHP script has been executed and the page has been loaded. To ensure a smooth redirection process, you can use PHP to output JavaScript code that performs the redirection. This way, the redirection will happen immediately after the PHP script is executed. 

<?php
// PHP code that needs to redirect to a different page
header("Content-Type: application/javascript");
echo "window.location.href = 'https://www.example.com';";
exit;
?>
