How can the use of regular expressions in PHP impact URL rewriting?

Regular expressions in PHP can be used to match and manipulate URLs, which is crucial for URL rewriting. By using regular expressions, you can create patterns that match specific URL structures and then rewrite them to a desired format. This allows for dynamic and flexible URL rewriting, making it easier to manage and maintain URLs on a website. 

// Example of using regular expressions in PHP for URL rewriting

// Original URL
$original_url = 'https://www.example.com/products.php?id=123';

// Rewrite rule using regular expression
$rewritten_url = preg_replace('/products\.php\?id=(\d+)/', 'product/$1', $original_url);

echo $rewritten_url; // Output: https://www.example.com/product/123
