What are some resources or tutorials that provide clear guidance on URL rewriting in PHP?

URL rewriting in PHP involves using .htaccess file to rewrite URLs for better readability and SEO purposes. One common use case is to convert dynamic URLs with query parameters into clean, user-friendly URLs. Here is a simple example of how to rewrite URLs using PHP: ``` RewriteEngine On RewriteRule ^products/([0-9]+)/?$ product.php?id=$1 [NC,L] ``` In this example, any URL that matches the pattern "products/{id}" will be rewritten to "product.php?id={id}". This allows for cleaner URLs and can improve SEO.
