Getting an access token for a local Facebook script

I will start this question by mentioning that this is my first experience with Facebook's API.

I have a script on my own PC, which is executed with WAMP. It fetches data from Facebook's Graph API, when given manually an access token from Graph API Explorer, getting a specific group's feed.

I would like my script to ask for an access token, and then just use file_get_contents to ask for the json string. I need the access token to have all the permissions available.

What should I do to make the next steps work?

  1. Open my PHP file. (already exists)
  2. The script will ask for an access token.
  3. It will print the content of https://graph.facebook.com/GROUP_ID/feed?=access_token=ACCESS_TOKEN

  1. If you are developing a facebook app, you don't need to login to facebook again. (Code snippets for both PHP and Javascript, use that is required to you.)

    [PHP]

    You can get the access_token by performing Http GET request on -

    https://graph.facebook.com/oauth/access_token?client_id=YOUR_APP_ID&client_secret=YOUR_APP_SECRET&grant_type=client_credentials

    For more details: login as app

    [Javascript]

    FB.getLoginStatus(function(response) 
{
  if (response.status === 'connected') 
  {
      var uid = response.authResponse.userID;
      var accessToken = response.authResponse.accessToken;
  } 
  else if (response.status === 'not_authorized') 
  {
     // the user is logged in to Facebook, 
     // but has not authenticated your app
  } 
  else 
  {
     // the user isn't logged in to Facebook.
  }
});

    For more details: getLoginStatus

  2. If you are integrating fb with your website, you need to login first and in the response you can obtain the access token.

    Read this: Login Architecture

    [PHP] (Difficulty: High)

    Read this: server-side-login

    [Javascript] (Dfifficulty: Low)

    FB.login(function(response) 
{
    if (response.authResponse)
    {
        console.log('Welcome!  Fetching your information.... ');
        var access_token = response.authResponse.accessToken;
    } 
    else 
    {
        console.log('User cancelled login or did not fully authorize.');
    }
 });

    More details: FB.Login

You're looking for server-side authentication. There is detailed documentation about this subject.
