How to get a friend list with the number of mutual friends?

Question

I'm developing a Facebook app, one of the things that I need is: a list with two columns - name and number of mutual friends. I want this for every friend I have.

I already saw the documentation and check that I can get what I want by this url (by http get request): https://graph.facebook.com/me/mutualfriends/FRIENDID.

But I don't known how to get the data from this url, I tried the http_get keyword unsucefully. I read somewhere to use curl instead. I'm a little confused about this.

Anyone knows how to do this in code, I just want to know how to manipulate the data inside the url.

Cheers

Thanks mariachi, that was i wanted. I made a loop to get all my friends and counted all mutual friends for each friend. However it tooks too long that I end with this error Fatal error: Maximum execution time of 30 seconds exceeded in C:\xampp\htdocs\app\php-sdk\src\base_facebook.php on line 809 and it hust print the first 15 friends.

Anyone knows a solution to this, maybe a faster way to get the number of mutual friends.

Answer 1

(I am assuming that you mean manipulating the data that is returned when you make that call).

This is the data returned in JSON when you make that call:

{
"data": [
  {
  "name": "FRIEND_NAME", 
  "id": "FRIEND_ID"
  }, 
  {
  "name": "FRIEND_NAME", 
  "id": "FRIEND_ID"
  }, 
  {
  "name": "FRIEND_NAME", 
  "id": "FRIEND_ID"
  }, 
  {
  "name": "FRIEND_NAME", 
  "id": "FRIEND_ID"
  }
 ],
}

So you can access the name as

$var_name=$returned_data[data][0][name];
$var_id=$returned_data[data][0][id];

try the mutual friend call on Graph Api Explorer to get a better understanding of the data returned
