Getting title and meta tags from external website

This is the way it should be:

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";

<?php// Assuming the above tags are at www.example.com$tags = get_meta_tags('http://www.example.com/');// Notice how the keys are all lowercase now, and// how . was replaced by _ in the key.echo $tags['author'];       // nameecho $tags['keywords'];     // php documentationecho $tags['description'];  // a php manualecho $tags['geo_position']; // 49.33;-86.59?>

get_meta_tags will help you with all but the title. To get the title just use a regex.

$url = 'http://some.url.com';preg_match("/<title>(.+)<\/title>/siU", file_get_contents($url), $matches);$title = $matches[1];

Hope that helps.
