Based on Michael Knapp's code, and adding some regex, here's a function that will get all meta tags and the title based on a URL. If there's an error, it will return false. Using the function getUrlContents(), also included, it takes care of META REFRESH re-directions, following up to the specified number of redirections. Please note that the regular expressions included were split into strings because php.net was complaining about the line being to long ;)

<?php
function getUrlData($url)
{
    $result = false;
   
    $contents = getUrlContents($url);

    if (isset($contents) && is_string($contents))
    {
        $title = null;
        $metaTags = null;
       
        preg_match('/<title>([^>])<\/title>/si', $contents, $match );

        if (isset($match) && is_array($match) && count($match) > 0)
        {
            $title = strip_tags($match[1]);
        }
       
        preg_match_all('/<[\s]meta[\s]name="?' . '([^>"])"?[\s]' . 'content="?([^>"])"?[\s][\/]?[\s]>/si', $contents, $match);
       
        if (isset($match) && is_array($match) && count($match) == 3)
        {
            $originals = $match[0];
            $names = $match[1];
            $values = $match[2];
           
            if (count($originals) == count($names) && count($names) == count($values))
            {
                $metaTags = array();
               
                for ($i=0, $limiti=count($names); $i < $limiti; $i++)
                {
                    $metaTags[$names[$i]] = array (
                        'html' => htmlentities($originals[$i]),
                        'value' => $values[$i]
                    );
                }
            }
        }
       
        $result = array (
            'title' => $title,
            'metaTags' => $metaTags
        );
    }
   
    return $result;
}

function getUrlContents($url, $maximumRedirections = null, $currentRedirection = 0)
{
    $result = false;
   
    $contents = @file_get_contents($url);
   
    // Check if we need to go somewhere else
   
    if (isset($contents) && is_string($contents))
    {
        preg_match_all('/<[\s]meta[\s]http-equiv="?REFRESH"?' . '[\s]content="?[0-9];[\s]URL[\s]=[\s]([^>"])"?' . '[\s][\/]?[\s]>/si', $contents, $match);
       
        if (isset($match) && is_array($match) && count($match) == 2 && count($match[1]) == 1)
        {
            if (!isset($maximumRedirections) || $currentRedirection < $maximumRedirections)
            {
                return getUrlContents($match[1][0], $maximumRedirections, ++$currentRedirection);
            }
           
            $result = false;
        }
        else
        {
            $result = $contents;
        }
    }
   
    return $contents;
}
?>

Here's an example of its usage. Check that the included URL has a META REFRESH redirection:

<?php
$result = getUrlData('http://www.marianoiglesias.com.ar/');

echo '<pre>'; print_r($result); echo '</pre>';

?>

For the above code the output would be:

<?php
Array
(
    [title] => Mariano Iglesias: El Eternauta   
    [metaTags] => Array
        (
            [description] => Array
                (
                    [html] => <meta name="description" content="Java, PHP, and some other technological mumble jumble. Also, some real-life stuff as well." />
                    [value] => Java, PHP, and some other technological mumble jumble. Also, some real-life stuff as well.
                )

            [DC.title] => Array
                (
                    [html] => <meta name="DC.title" content="Mariano Iglesias - Weblog" />
                    [value] => Mariano Iglesias - Weblog
                )

            [ICBM] => Array
                (
                    [html] => <meta name="ICBM" content="-34.6017, -58.3956" />

                )

                (

                    [value] => -34.6017;-58.3956
                )

            [geo.region] => Array
                (
                    [html] => <meta name="geo.region" content="AR-BA">
                    [value] => AR-BA
                )

            [geo.placename] => Array
                (
                    [html] => <meta name="geo.placename" content="Buenos Aires">
                    [value] => Buenos Aires
                )

        )

)
