How can .htaccess be utilized to manage URL redirection in PHP?

To manage URL redirection in PHP using .htaccess, you can set up rules in the .htaccess file to redirect certain URLs to different pages on your website. This can be useful for creating clean and user-friendly URLs, redirecting old URLs to new ones, or implementing URL shortening.

```php
RewriteEngine On
RewriteRule ^old-url$ /new-url [L,R=301]
```

This code snippet will redirect any requests for "old-url" to "new-url" with a 301 (permanent) redirect status. Make sure to replace "old-url" and "new-url" with the actual URLs you want to redirect.
