Installing, Configuring PHP and Running PHP scripts

In order to run PHP on your Windows system, you can simply have the required version of regular or debug PHP zip files and extract them.  And then ensure that extracted location is in %PATH% so that Windows starts picking up that particular version of php by defult for running .php scripts/files locally.

Example: On the same system you can run multiple versions of PHP side-by-side.
