How can the $_SERVER['REQUEST_URI'] variable be utilized in PHP to retrieve specific values from URLs?

To retrieve specific values from URLs using the $_SERVER['REQUEST_URI'] variable in PHP, you can use functions like parse_url() and explode() to extract the desired information. By breaking down the URL into its components, you can then access and manipulate specific parts such as query parameters or segments. 

$url = $_SERVER['REQUEST_URI'];
$parts = parse_url($url);
$path = explode('/', $parts['path']);
$specific_value = $path[2]; // Retrieve the third segment of the URL path
echo $specific_value;
