What is the difference between a URL path and a file path in PHP?

In PHP, a URL path refers to the address used to access a web page or resource on the internet, typically starting with "http://" or "https://". On the other hand, a file path in PHP refers to the location of a file on the server's filesystem. To convert a URL path to a file path in PHP, you can use the `parse_url()` function to extract the path component from the URL.

$url = "https://www.example.com/path/to/file.php";
$parsed_url = parse_url($url);
$file_path = $_SERVER['DOCUMENT_ROOT'] . $parsed_url['path'];
echo $file_path;
