I have an array of 'servers' that I'm storing in a JSON file.

The JSON file looks like this:
`{"1":{"available":1,"players":0,"maxplayers":4}}`

I retrieve this value with this:

```
$servers = (array) json_decode(file_get_contents("activeservers.json"));

```

However, when I try to access the array with `$server = $servers[$id]`, `$server` is null. I noticed that the key is in quotes, so I also tried casting `$id` to a string, and surrounding it with quotes (") which didn't work.

Something to note, is that this code is returning "NULL":

```
foreach(array_keys($servers) as $key){
    var_dump($servers[$key]);
}

```
