I'm trying to loop through the results from the Last.fm API but it's not working.
function get_url($url){
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,5);
$content = curl_exec($ch);
curl_close($ch);
return $content;
}
$xml = get_url('http://ws.audioscrobbler.com/2.0/?method=album.search&album=kid%20a&api_key=b25b959554ed76058ac220b7b2e0a026');
$doc = new SimpleXMLElement($xml);
$albums = $doc->results->albummatches;
foreach($albums as $album){
echo $album->album->name;
}
This just shows the first album. If I change the code within the foreach loop to echo $album->name; it shows nothing at all.
What am I doing wrong?
