# Friends?

## Problem

I need to determine whether two (or more) users are friends.

## Solution

Use the `Friends.areFriends()` method:

`\$areFriends = \$facebook->api_client->friends_areFriends('12345', '67890');`

The method also accepts two arrays and will let you know whether each pair (pulling the member at the same position in each array) is a friend:

```\$aUsers = array('12345', '67890', '11223');
\$bUsers = array('33445', '66778', '99100');

## Discussion

Either way, the `Friends.areFriends()` returns a multidimensional array in which each element contains `uid1`, `uid2`, and `are_friends` elements (with the latter being `true`, `false`, or empty if the members aren’t visible due to privacy rules or don’t exist, which is the case with our fictional users here):

```Array
(
[0] => Array
(
[uid1] => 12345
[uid2] => 33445
[are_friends] =>
)

[1] => Array
(
[uid1] => 67890
[uid2] => 66778
[are_friends] =>
)

[2] => Array
(
[uid1] => 11223
[uid2] => 99100
[are_friends] =>
)
)```

Since the method is symmetric, both arrays need to have the same number of elements in them or you’ll get an invalid parameter error.

### FQL equivalent

If you’d prefer to use FQL to access friends, the equivalent query is:

`SELECT uid1, uid2 FROM friend WHERE uid1=uid1 AND uid2=uid2`
