How To get vimeo video thumubanil using php?

Hi all.. Please anyone help me to get vimeo thumbnail to show in my blog post? I'm looking for a php function where it ll take vimeo video id as parameter and ll return its thumbnail Thanks in advance.

 

Google found this:

function getVimeoThumb($videoid,$size) {
    $url = "vimeo.com/api/clip/".$videoid."/php/";
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    // grab URL and pass it to the browser
    $data = curl_exec($ch);
    curl_close($ch);
    $finaldata = unserialize($data);
    
    return '';
}

PHP:

    $video_url = "http://vimeo.com/7811853"  
    $file = fopen($video_url, "r");
    $filedata = stream_get_contents($file);
    $html_content = strpos($filedata,"<link rel=\"videothumbnail");
    $link_string = substr($filedata, $html_content, 128);
    $video_id_array = explode("\"", $link_string);
    $thumbnail_url = $video_id_array[3];
    echo $thumbnail_url;
