html - PHP to get meta tags after <head> tag -

-

i want meta tags external url. unfortunately, meta tags on website placed after tag. use get_meta_tags($url) didn't work. here external url source , meta tag description exist @ last.

<html><meta http-equiv="content-type" content="text/html; charset=utf-8"> <head><title>tools</title> </head> <body><h2>sitemap notification received</h2> <br> sitemap has been added our list of sitemaps crawl. if first time notifying google sitemap, please add via  <a href="http://www.google.com/webmasters/tools/">http://www.google.com/webmasters/tools/</a>  can track status. please note not add submitted urls our index, , cannot make predictions or guarantees when or if appear.</body></html> <meta name='description' content='200'>

this function should you:

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 , display need: $title = $nodes->item(0)->nodevalue;  $metas = $doc->getelementsbytagname('meta');  ($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";

or easier this:

<?php // assuming above tags @ www.example.com $tags = get_meta_tags('http://www.example.com/');  // notice how keys lowercase now, , // how . replaced _ in key. echo $tags['author'];       // name echo $tags['keywords'];     // php documentation echo $tags['description'];  // php manual echo $tags['geo_position']; // 49.33;-86.59 ?>
