Is my code ok ?

Hi Guys

I am using the func below to get the last number from the URL. It works, but I want to know if there is a better way to do it:

 

example url: mysite.com/courses/100/ (100 is the post id)

 

//Get the 100 from the URL

$current_uri = $_SERVER['REQUEST_URI'];

$data = explode("/", $current_uri);

$post_id = $data[count($data)-2];

$post_id = filter_var($post_id, FILTER_VALIDATE_INT);

echo "The number is" . $post_id;
