这应该是这样的：
function file_get_contents_curl($url){ $ch = curl_init(); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); $data = curl_exec($ch); curl_close($ch); return $data;}$html = file_get_contents_curl("http://example.com/");//parsing begins here:$doc = new DOMdocument();@$doc->loadHTML($html);$nodes = $doc->getElementsByTagName('title');//get and display what you need:$title = $nodes->item(0)->nodevalue;$metas = $doc->getElementsByTagName('meta');for ($i = 0; $i < $metas->length; $i++){ $meta = $metas->item($i); if($meta->getAttribute('name') == 'description') $description = $meta->getAttribute('content'); if($meta->getAttribute('name') == 'keywords') $keywords = $meta->getAttribute('content');}echo "Title: $title". '<br/><br/>';echo "Description: $description". '<br/><br/>';echo "Keywords: $keywords";
