PHP regex to match Vimeo text OR html link

I'm looking for a PHP regex that will scan a block of text and match any Vimeo URLs--either as plain text or in HTML links, so I can replace them with embedded videos.

I have a version of each working, but I'm not skilled enough to augment them so that it'll do both, and a lot of the half-working ones I've found don't seem to account for the wrinkles listed here: https://stackoverflow.com/a/12263701/1402052

The one that seems to effectively match HTML links:

$text = preg_replace('#(.*?)http://(www\.)?vimeo\.com/([^ ?\n/]+)((\?|/).*?(\n|\s))?.*#x', '<div class="video vimeo"><iframe src="//player.vimeo.com/video/$3" width="650" height="366" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe></div>', $text);

The one that seems to effectively match plain text URLs:

$text = preg_replace('#http://(www\.)?vimeo\.com/(\d+)#', '<div class="video vimeo"><iframe src="//player.vimeo.com/video/$2" width="650" height="366" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe></div>', $text);

These also seem to work if I run both (the former first), but I'm guessing there's a much better way.

Also, I say "seems to" because I haven't stressed tested either sufficiently yet. Any help is appreciated. :)

You can use Simple HTML DOM here:

define( 
    'VIMEO_URL_PATTERN' ,
    '~https?://(?:www\.)?vimeo\.com/.*?/?(\d+)~i'
);
define(
    'URL_REPLACEMENT' ,
    '<div ... <iframe src="//player.vimeo.com/video/$1...</div>'
);

$html = ... // Load HTML code here

// Change links
foreach($html->find('a') as $link) {
    if (
       preg_match(
            VIMEO_URL_PATTERN,
            $link->href,
            $matches
       )
    ) {
        $link->outertext = preg_replace( 
              VIMEO_URL_PATTERN,
              URL_REPLACEMENT,
              $link->href
        );
    }
}

// Change text
foreach($html->find('text') as $text) {
    $text->outertext = preg_replace(
           VIMEO_URL_PATTERN,
           URL_REPLACEMENT,
           $text
    );
}

echo $html;
