Many applications in languages like PHP and CMS like Joomla require the use of a local webserver to test and debug applications.
IIS can be used in Windows, but, PHP and mySQL needs to be installed separately for IIS.
As an alternative,i recommend WampServer can be used.
WAMP = Web server + PHP + mySQL
WAMP is a one click install web server, just install the software and it will start to run in system tray, click on it and select “Put online“.
Your website / web application needs to be placed in “C:\wamp\www” folder, if “C” is your system drive.
Your webserver can be accessed at this location, http://localhost/ or http://127.0.0.1
Make sure to allow firewall exceptions in order for the server to work.
