You can use the iTunes Search API to fetch Podcast Information which will have the Track Title and Image.
Using your URL as an example, you can strip out the id "90206964" and use CURL.
function getID($url) {
$id_pos = strpos($url, "/id") + 3;
$length = strpos($url, "?", $id_pos) - $id_pos;
return substr($url, $id_pos, $length);
}
function fetchFromiTunes($id) {
$ch = curl_init("https://itunes.apple.com/lookup?id=" . $id);
$options = array(
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HTTPHEADER => array('Content-type: application/json') ,
);
curl_setopt_array( $ch, $options );
$results = curl_exec($ch);
$results = json_decode($results,true);
echo "[Podcast Title]" . $results["results"][0]["collectionName"] . "
[Artwork]" . $results["results"][0]["artworkUrl600"] . "
";
curl_close($ch);
}
