Question

Okay, here’s a fun one.

I need to figure out what source a user is referencing when entering a copy and pasted Vimeo URL into an input box. For those that are unfamiliar, Vimeo currently has 4 different sources that are accessible through their simple API:

Videos belonging to a user

Valid URL structure: http://vimeo.com/user3825208 or https://vimeo.com/davekiss

Videos belonging to a group

Valid URL structure: http://vimeo.com/groups/eos550d or https://vimeo.com/groups/162

Videos belonging to a channel

Valid URL structure: http://vimeo.com/channels/hd or https://vimeo.com/channels/201

Videos belonging to an album

Valid URL structure: http://vimeo.com/album/1919683 or https://vimeo.com/album/mycustomname

So basically, I want to be able to run the URL into a function which will tell me what source the URL belongs to.

I’ve been using this for videos belonging to a user, but now I need to expand to all sources.

sscanf(parse_url($url, PHP_URL_PATH), '/%d', $video_id);

Maybe I should do this four times? preg_match('???', $url);

Thanks for your help!

You don’t need regular expressions:

function discoverVimeo($url)
{
    if ((($url = parse_url($url)) !== false) && (preg_match('~vimeo[.]com$~', $url['host']) > 0))
    {
        $url = array_filter(explode('/', $url['path']), 'strlen');

        if (in_array($url[0], array('album', 'channels', 'groups')) !== true)
        {
            array_unshift($url, 'users');
        }

        return array('type' => rtrim(array_shift($url), 's'), 'id' => array_shift($url));
    }

    return false;
}

The following will return an array, with an index id and another index type, that will be one of:

• user
• album
• channel
• group
