What are the differences between using PHP and Apache for URL redirection, and which method is more efficient?

When it comes to URL redirection, using Apache's mod_rewrite module is generally more efficient than using PHP for redirection. This is because Apache can handle redirection at the server level before PHP even gets involved, resulting in faster redirection and less server load. 

// Apache mod_rewrite method for URL redirection
// Create a .htaccess file in the root directory of your website with the following content:

RewriteEngine on
RewriteCond %{REQUEST_URI} ^/old-url$
RewriteRule ^(.*)$ /new-url [R=301,L]
