How to iterate all records from an API call?

I'm attempting to use the VirusTotal API to return the virus scan for a certain file. I've been able to get my current PHP code to upload the file to VirusTotal as well as get the results in an array. My question is, how would I get the [detected] value from every virus scanner under the scans object? My PHP code is below as well as a link to the output of the array.

require_once('VirusTotalApiV2.php');

/* Initialize the VirusTotalApi class. */
$api = new VirusTotalAPIV2('');

if (!isset($_GET["hash"])) {
    $result = $api->scanFile('file.exe');
    $scanId = $api->getScanID($result);
    $api->displayResult($result);
} else {
    $report = $api->getFileReport($_GET["hash"]);
    $api->displayResult($report);
    print($api->getSubmissionDate($report) . '<br>');
    print($api->getReportPermalink($report, TRUE) . '<br>');
}

You would probably have to iterate each object under scans in a for loop and either store them in yet another array or echo them out of just want to print. For example

$detectedA = {nProtect, CAT-QuickHeal, McAfee...nth};
$datContainer = array();

for ($i = 0; i < $api.length ; i++){

   //Either store in an array
   $api->$scans->detectedA(i)-> detected = $datContainer(i);

   //Or echo it all
   echo $api->$scans->detectedA(i)->detected;

   return true;

}

Granted that's probably not the way you access that object but the idea still applies.
