In this screen cast, I have demonstrated how to install php, mysql and apache on your PC so that you can start programming in php. Here is quick summary:
1. Download and install xampp from following website. It contains php, mysql and apache. https://www.apachefriends.org/
2. xampp will install everything by default in c:\xampp folder and will run its control panel.
3. Start apache and mysql through control panel.
4. To run xampp control panel after you restart your PC, go to c:\htdocs folder and click on the 'xampp-control' file.
5. To run your php programs, you will create them or copy them in c:\xampp\htdocs folder or sub folders.
6: If you type 'localhost' in google chrome or firefox, you will see the webpage installed by xampp. You can browse to see some information here but the most useful link right now is 'phpMyAdmin' which is a browser based software to manage your mysql databases.
