[wp-hackers] Checking plugin version

[Chris McCoy]

To get the plugin ver you can do something like this

    $url = 'http://api.wordpress.org/plugins/info/1.0/wordpress-seo/';

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $result = curl_exec($ch);
    curl_close($ch);

    $result = unserialize($result);
    echo $result->version;

I'm interested in "Finding out about current WP directory plugin versions,
by querying http://api.wordpress.org".

To query wordshell i need to know plugin slug - how i can get it?
