Before we get into PHP, we have to install xampp. Xampp is a package which consists of Apache HTTP server / web server, mysql, php and perl. xampp is freely available
http://www.apachefriends.org/en/xampp-windows.html. Download it and install. And then start the xampp control panel by running xampp-control.exe inside xampp folder (in case of windows) and start the apache, mysql, filezilla services. And now open your browser and type the url "http://localhost/xampp". If xampp home page is displayed then you have successfully installed and set up a xampp environment on your os to run php scripts.
