Click on Desktop xampp icon and click on the apache start button
if not present in desktop icon then go c://xampp/xampp-control.exe
3) open notepad and create .php file
under c:/xampp/htdocs/foldername (create new folder first time and save file)
<?php
echo "hello world";
?>
save php file using .php extension
4) open browser and type localhost/folder name
<?php
echo "hello world";
?>
save php file using .php extension
4) open browser and type localhost/folder name
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
