RussianThere is a way to do this actually. Well if you are talking about having a "Tab" on your facebook page that has your website, or your php code on there. In order to do this, you will need to have an SSL, for since one of the most recent facebook updates, they require the code you display on their site to be secure.
You will want to check on here for how to create a facebook canvas page. Here is a very good tutorial to do that:
I'm not sure if this is exactly what you were looking for, but if it is, I know this works, I used to run my whole website through a tab. Hope this helps!
Oh, and not sure if they have to like your page in order to see it. I know a while back that used to be the case. But facebook has had so many updates, I dont know if they have removed that or not.
Get started on your facebook here: developers.facebook.com/apps
UPDATED
You are creating a canvas app. Which can be added on facebook to other facebook pages. Not just yours. But big chances are, people arent going to add a random app that has nothing to do to your page on their page. But since you would like to have php content on your facebook page, this is the only way to do that. The polls app you sent me, the reason that requires people to like their page before they continue, is because the app is not on their page itself. When you create an app. It is given its own app url. So, I am guessing, if you really wanted to, you could add facebook code on your app that you are making, to require them to like your page before they submit, or something. Im not sure of the code to do this.
Now to answer your questions:
The tap app is availible when you add it to your page, any user that gets on your page can see it. And anyone whom your send your url too the app page, can add it to their page... you probably would want to do that anyways, since you just want your code on your page. You would only submit it to the facebook directory if you wanted people to find your app and add it to their pages. But I dont think this is what you are wanting to do.
As far as the secure page. Sadly, the answer is yes, it has to be secure to even test it. I actually found out that facebook update the hard way, when I noticed all my code was just blank each time I was trying to test it. Then later found their update required a SSL Certificate for your page the content is pulling from.
To answer you other questions:
When you add a tab to your page. If someone clicks on the tab. It is still on your facebook page. Its almost like someone clicking on your page photos. It doesnt leave your page, if just show all your photos. The tab is basically the same thing.
Sadly, facebook has remove the option to allow tabs to be the landing page when someone goes to your page. So there is no way Im sure, that I know of, to display the code on your facebook original page.
Now with the adding the tab to your facebook page, let me explain it like this. You know the area where you enter your page tab URL and your secure page tab URL. Well look at that as, telling your app to pull from that page. Which basically displays that page in an iframe on the facebook tab. Now when you go to register. Remember how earlier I said, your page isnt listed in the facebook directory. When this is the way to actually get to your app page: http://www.facebook.com/dialog/pagetab?app_id=YOUR_APP_ID&next=YOUR_URL
You are basically entering your UNIQUE APP ID... since many people can use the same URL for different apps, then at the end just page the same URL that you entered for your website field.
This isnt a hack, but just the actually way to get to the page itself. Registering the app, is only if you want to let it show up in the facebook directory, which again, I dont think is something you are really wanting to do. That is mainly for big company's like, lets say, Instagram. I think they created an app, that is in the directory, that users can find and add to thier page, then enter certain information to allow their photos, and stuff to show up. But that is the premise for registering an app. So I wouldnt worry about that, unless the app you are making, you are trying to make for other pages to add for their page.
As of which user is viewing your page tab. I do not know. As far as the coding of facebook apps. I'm not very familiar with. I only used the apps to display my website, and contact forms on facebook pages. It is possible that this displays on your facebook insights for your page. But I am not sure. I do hope this information will be helpful to you, and hope you can figure out what you are trying to do.
UPDATE:
So Im not sure why its not viewable for non-admin viewers... Im guessing there might have been another facebook update with that... but I did some research and found something that will solve all your problems.. I dont think you even need a SSL certificate with this:
