With PHP you only need to add one line to IIS Module Mapping for it to start working.
With MySQL you have two options.
You either need to include it in your PATH, or add a service into registry. Let’s try both ways.
(01) To add a new element to your PATH, use advanced system properties.
(02) Second way is a good choice,if you have access to a very similar MySQL install with the same paths. You can Export HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesMySQL and merge back into your target instance.
You have to restart for the service to appear in the list. It already will be started
