What steps can be taken to make URLs more user-friendly and SEO-friendly in PHP applications?

To make URLs more user-friendly and SEO-friendly in PHP applications, you can use URL rewriting techniques to create clean and descriptive URLs. This can be achieved by using mod_rewrite in Apache or similar techniques in other web servers. Additionally, you can utilize PHP to dynamically generate URLs based on the content being displayed on the website.

// Example of URL rewriting in .htaccess file for Apache web server
RewriteEngine On
RewriteRule ^products/([0-9]+)/?$ product.php?id=$1 [NC,L]

// Example of dynamically generating SEO-friendly URLs in PHP
$id = 123;
$title = "example-product-title";
$url = "https://www.example.com/products/{$id}/{$title}";
echo $url;
