how to get the full URL in PHP of current web page ?
How can I retrieve the full URL of the current web page using PHP? For example, let's say I want to display the full URL of the page in the browser's address bar in a message or store it in a database. What is the method for retrieving this information using PHP?
Furthermore, how can I handle situations where the URL contains query parameters or fragments? And is it possible to obtain the protocol and domain name along with the full URL of the current page?
