extracting meta data
hi guys does php have any built in functions that would
allow me to extract meta description and meta keywords?
I’m building a link partner directory, and would like for this
info to be automatically extracted from the page that
is being submitted.
It would be displayed in a form that can be editted
before being submitted. Some pages already have a good
description and keywords in their meta data, so if it could
be extracted the submitter could save time by not typing
in a description and keywords.
if there are no built in functions, could it be done without
needing to use regular expressions?

<?php
$keywords = $description = '';
$dom = new DomDocument();
$dom->loadHTMLFile('http://www.charles-reace.com/');
$metaList = $dom->getElementsByTagName('meta');
for($ix = 0, $total = $metaList->length; $ix < $total; $ix++)
{
$node = $metaList->item($ix);
if(strtolower($node->getAttribute('name')) == 'keywords')
{
$keywords = $node->getAttribute('content');
}
elseif(strtolower($node->getAttribute('name')) == 'description')
{
$description = $node->getAttribute('content');
}
}
echo "<p><strong>Keywords:</strong> $keywords</p>n";
echo "<p><strong>Description:</strong> $description</p>n";
?>
