Can't parse this JSON in php

Question

I'm trying to get off some mails from Yahoo Query Language using OAuth, everything is fine and alright, except, YQL returns JSON, and somehow I'm not able to parse it!

I'm able to parse simple JSONs like

'{"hello":"world"}'

but not this one:

{
"query": {
    "count": 1,
    "created": "2012-08-11T19:22:51Z",
    "lang": "en-US",
    "results": {
        "result": {
            "messageInfo": [
                {
                    "from": {
                        "name": "account-services-us@cc.yahoo-inc.com"
                    },
                    "subject": "Success! You have shared your Yahoo! information"
                },
                {
                    "from": {
                        "name": "account-services-in@cc.yahoo-inc.com"
                    },
                    "subject": "Success! You have shared your Yahoo! information."
                },
                {
                    "from": {
                        "name": "account-services-in@cc.yahoo-inc.com"
                    },
                    "subject": "Success! You have shared your Yahoo! information."
                },
                {
                    "from": {
                        "name": "Yahoo!"
                    },
                    "subject": "Welcome to Yahoo!"
                }
            ]
        }
    }
}
}

I tried validating it in http://jsonlint.com/

and it's valid!

Edit: I need to display 'from:name' and 'subject' in a table like structure.

The code snippet I wrote is this:

$sdata = call_yql(OAUTH_CONSUMER_KEY, OAUTH_CONSUMER_SECRET,
               $access_token, $access_token_secret,
               false, true);
$json_data = json_encode($sdata);
$mails = json_decode($json_data);
print_r($mails->query);

The Error i get is:

Notice: Trying to get property of non-object in C:\xampp\htdocs\yahoo\txtweb\yql.php       on line 21

See this url:-

Parsing JSON file with PHP

see also this url

or try it

To iterator over a multidimensional array, you can use the RecursiveArrayIterator

$jsonIterator = new RecursiveIteratorIterator(
    new RecursiveArrayIterator(json_decode($json, TRUE)),
    RecursiveIteratorIterator::SELF_FIRST);

foreach ($jsonIterator as $key => $val) {
    if(is_array($val)) {
        echo "$key:\n";
    } else {
        echo "$key => $val\n";
    }
}
