Вот вариант рабочего кода:
$url = "http://l2oops.com/";
$uagent = "Opera/9.80 (Windows NT 6.1; WOW64) Presto/2.12.388 Version/12.14";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_ENCODING, "");
curl_setopt($ch, CURLOPT_USERAGENT, $uagent);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 120);
curl_setopt($ch, CURLOPT_TIMEOUT, 120);
curl_setopt($ch, CURLOPT_MAXREDIRS, 10);
curl_setopt ($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
$contents = curl_exec( $ch );
$err = curl_errno( $ch );
$errmsg = curl_error( $ch );
$header = curl_getinfo( $ch );
curl_close( $ch );
