Internal Working of PHP:-

When we click on a file or direct URL from browser address bar then it will create HttpRequest Object and Send to Apache Web Server.

Apache Web Server will get requests,process the requested file , generate a result, and convert the result into HTML form and send back to the browser using HttpResponse Object.

Url locate Server Address using localhost or remote server.

for example, http://localhost/php11/Demo1.php is a localhost URL for testing purpose or desktop-based web application.

for example http://shivaconceptsolution.com/digital/  It is the remote URL because shivaconceptsolution.com is domain name which points to a remote server
