file_get_contents falla

[Serenity]

Gracias Andrés,

Este es el código:

$xml_get=file_get_contents("http://xml.travel.com/xml/getQuoteHotels?r1k3a=$r1k3a&r2a=$r2a&r2k=$r2k&r2k1 a=$r2k1a&r2k2a=$r2k2a&r2k3a=$r2k3a&r3a=$r3a&r3k=$r 3k&r3k1a=$r3k1a&r3k2a=$r3k2a&r3k3a=$r3k3a&r4a=$r4a &r4k=$r4k&r4k1a=$r4k1a&r4k2a=$r4k2a&r4k3a=$r4k3a&r 5a=$r5a&r5k=$r5k&r5k1a=$r5k1a&r5k2a=$r5k2a&r5k3a=$ r5k3a&d=$d&l=ESP&co=MX");

$xml = new SimpleXMLElement($xml_get);

foreach($xml->hotels->hotel as $item){
$hoteles[] = array("idhotel"=>(int)$item->hotelid, "hotelname"=>(string)($item->hotelname),"ciudad"=>(string)$item->cityname,"ubicacionid"=>(string)$item->ubicationid,"categoria"=>(string)$item->categoryid,"tarifaneta"=>(int)$item->rooms->Roomrates->rate);
}


Incluyendo el Try que me sugieres devolvió:

Error String could not be parsed as XML
