$header[] = "Connection: keep-alive";

$cookie="cookie.txt";
$fp=fopen($cookie,"w+");

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_REFERER,$referer);
curl_setopt($ch, CURLOPT_TIMEOUT, 900);

        $content1=$array1[1];
        $array2=explode('">

        $content2=$array2[0];
        $EVENTTARGET=urlencode($content2);

        $content2=$array2[0];
        $EVENTARGUMENT=urlencode($content2);
    }

    if(stristr($content,"formNowPlaying")){

        $content1=$array1[1];
        $array2=explode('">

        $content2=$array2[0];
        $nexturl=$content2;
    }

//echo $EVENTTARGET." ".$EVENTARGUMENT." ".$nexturl;

$url = "http://mediaforest.biz/mobile/".$nexturl;

$fields = "EVENTTARGET=".$EVENTTARGET."&__EVENTARGUMENT=".$EVENTARGUMENT."&MyChannels=0&ViewChannel_Button=Show";

Answer 1

I don't have much experience with cURL, and I didn't look into it, but at first glance it appears that this:

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);

needs to be this:

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

Could be wrong though.

Answer 2

If you're getting data from the first request, try closing afterwards (for each request).

$content=curl_exec($ch); 
curl_close($ch); 
echo $content;

and

$content_stage2=curl_exec($ch);
curl_close($ch);    
echo $content_stage2;
