php-url-meta

Extract some basic metadata about a URL. In most cases it favors Open Graph (OG) markup, and will fall back to standard meta tags if necessary.

parse() returns an object with title, description, keywords, author, and image. Most values are string EXCEPT keywords and author (which are their own objects).

Usage:

<?php
require('meta.php');
$m = new URLMeta('http://www.imdb.com/title/tt0120737/');
if ($resp = $m->parse()) {
  var_dump($resp);
} else {
  print $m->error_code . "\n" . $m->error_response;
}
?>

Response:
