How can mod_rewrite be used to achieve the desired outcome in PHP?

To achieve the desired outcome in PHP using mod_rewrite, you can rewrite URLs to make them more user-friendly or to redirect requests to different pages on your website. This can help improve SEO, create cleaner URLs, and enhance user experience.

```php
RewriteEngine On
RewriteRule ^products/([0-9]+)$ product.php?id=$1 [L]
```

This code snippet uses mod_rewrite to rewrite a URL from `product.php?id=1` to `products/1`. This makes the URL more user-friendly and easier to remember.
