Fetch Steam API information to page

I have found a great Steam API from Valve them self and I wonder now how I can put the specific information one by one. Example: $steam['response']['players']['personastate']. It doesn't need to be that solution. I just typed something :)

The request will be like this one below:

{
    "response": {
        "players": [
            {
                "steamid": "{hidden}",
                "communityvisibilitystate": 3,
                "profilestate": 1,
             开发者_开发知识库   "personaname": "nhagyavi",
                "lastlogoff": 1317692549,
                "commentpermission": 1,
                "profileurl": "http:\/\/steamcommunity.com\/id\/nhagyavi\/",
                "avatar": "http:\/\/media.steampowered.com\/steamcommunity\/public\/images\/avatars\/c2\/c25479aeea82f85eb1134bfcc8e064dcef1d361f.jpg",
                "avatarmedium": "http:\/\/media.steampowered.com\/steamcommunity\/public\/images\/avatars\/c2\/c25479aeea82f85eb1134bfcc8e064dcef1d361f_medium.jpg",
                "avatarfull": "http:\/\/media.steampowered.com\/steamcommunity\/public\/images\/avatars\/c2\/c25479aeea82f85eb1134bfcc8e064dcef1d361f_full.jpg",
                "personastate": 1,
                "realname": "Erik Edgren",
                "primaryclanid": "103582791429525632",
                "timecreated": 1106321372,
                "gameserverip": "217.163.23.35:7777",
                "gameextrainfo": "Red Orchestra 2: Heroes of Stalingrad",
                "gameid": "35450",
                "gameserversteamid": "90083758048089092",
                "loccountrycode": "SE",
                "locstatecode": "{hidden}",
                "loccityid": {hidden}
            }
        ]

    }
}

How do I fix this? Thanks in advance!

Looks like JSON. You need json.decode

$json_object=
file_get_contents("http://api.steampowered.com/");

        $json_decoded = json_decode($json_object);
        //var_dump($json_decoded);
        echo $json_decoded->response->players[0]->lastlogoff;

Outputs
