I am attempting to use a recursive function to search through a multidimensional array, such as the one below, to find certain values, i.e. people who went to certain school, majored in a certain subject, hold a certain job title, etc. In case your wondering, this array is output from the Facebook Graph API. In reality there are more than 3 offset arrays, depending on the number of friends a user has, it could be in the thousands. 

Here's a solution I tried with very little knowledge of recursive functions (my first thought was to use in\_array before I found out it didn't work for md arrays):

So to give you an idea of how the md array below works, check out this snippet of code:

```
$friend = $fqlResult[0]['name'];
echo "$friend";

```

\*The output would be "BLANK" since I deleted the person's name.

```
$data = $fqlResult;
$collegemajor = (isset($value['education'][0]['concentration'][0]['name'])) ? $value['education'][0]['concentration'][0]['name'] : null ;
$major = "Business Administration";
if (isset($collegemajor)) {
    foreach($data as $key=> $value) {
          if ($value($collegemajor) == $major) {
              echo "User $key is majoring in $major";
     }
  }
}

```

So here is the multidimensional array referenced above. In this example, I want to pull the names of all of the user's friends who majored in Business Admin. in college. As you can see from this snippet, there aren't any (I think) but in the long version of the array, there are plenty. The code above produces no output and I'm lost as to how to make it work. Any help would be greatly appreciated.
