You probably don't need regex, you can try get_meta_tags():

thanks your reply, its not getting uppercase meta tage
eg:
<META NAME="DESCRIPTION"
<meta name="Descriptions"

Be aware that array keys are case sensitive.

Did you try

$tags = get_meta_tags('http://www.example.com/');

echo $tags['DESCRIPTION'];   
echo $tags['Descriptions'];     

What you can do is strtolower the keys in the $tags array and check those.

function cleanMeta($tags)
{
    $keys = array_map('strtolower', array_keys($tags));
    $values = array_values($tags);
    return array_combine($keys, $values);
}

$tags = cleanMeta(get_meta_tags('hangman.php'));

print_r($tags);
