              (

                                        [0] => Array
                                            (
                                           [startTime] => 2014-04-03T00:00:00Z

Please check my code below. I want to get values of "webinarkey" and "subject" and "start date - with date formatted" and put them into my select box. I can now populate "webinarkey and "subject". Thank you all to help to to populate "webinarkey and subject" but now i want to show "start date with date format as well.

  echo '<form method="POST"><select>';
  foreach ($data["upcoming"]["webinars"] as $webinar) {
  echo '<option value="' . htmlspecialchars($webinar["webinarKey"]) . '">' . htmlspecialchars($webinar["subject"]) . htmlspecialchars($webinar["times"]["startTime"]) . '</option>';

}
    echo '</select></form>';

Please help me to show start date as well.

$data = array(/**/);
foreach ($data["upcoming"]["webinars"] as $webinar) {
    echo '<option value="' . htmlspecialchars($webinar["webinarKey"]) . '">' . htmlspecialchars($webinar["subject"]) . '</option>';
}

From what I gather the only array you need to loop over is $data["upcoming"]["webinars"].

Ensure your output HTML is valid and your data is escaped properly.
