Mas maayo unta toh dli WAMPserver imo gi install or XAMPP or unsa. These are just abstractions to make it easy for you to setup your work station. If ganahan jd ka mu kat-on. Mas maayo if kasabot ka unsa jd ng PHP ug unsaon na siya pag padagan.
PHP is an interpreted language, meaning dli siya kelangan i-compile. What it needs to run is a webserver that can interpret PHP (ie. Apache, nginx, etc). Install a webserver then read the PHP documentation on how to add the PHP module sa imo webserver. It will be extremely difficult to newbies, but is a necessary pain to endure if you want to start right. And I will always believe in starting out right.
If you get stuck, ask here for specific question. Or Google. Chances are other people have succeeded where you are failing and have posted their solutions online.
Learning the language itself (if you're already a programmer of some other language) will be easier than you think as it is a language based on and built on C. Setting it up manually will provide a good foundation of the basics that you need to understand when working with PHP.
