Thanks Tom. I have already tried these two. My problem is, I always get the "Rate limit exceeded. Clients may not make more than 150 requests per hour." error message, even if this is the first time I log in. I thought it could be possible if the user is logged in using oAuth.
Let's say I want to get the list of profiles followed by @Twitter: <?php $curl = curl_init(); curl_setopt($curl,CURLOPT_URL,"http://api.twitter.com/1/friends/ids/ twitter.xml"); curl_setopt($curl,CURLOPT_RETURNTRANSFER,true); $contenu = curl_exec($curl); $xml = new simpleXMLElement($contenu); print_r($xml); foreach ($xml->ids->id as $friend) { echo $friend."<br>"; } ?> What am I doing wrong?
