In the context of PHP, how can clean URLs be effectively implemented to maintain user-friendly navigation?
Clean URLs can be implemented in PHP by using mod_rewrite to rewrite URLs in a user-friendly format. This can be achieved by creating a .htaccess file with rewrite rules that map clean URLs to their corresponding PHP files. This not only improves the readability of URLs but also enhances the user experience by making navigation more intuitive.
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
