Before we can get in to any PHP, we first need to have somewhere to actually host the scripts we create. You can either find a hosting provider, create your own web server or request hosting here. If you are interested in creating your web server, I would recommend following this guide.
Once you have a web server, you can go to part there where we can set up our IDE which we will use to develop our web applications. If you have received the hosting from here, this will already be set up for you.
