复制代码 代码如下:

function video_image($url){

$image_url = parse_url($url);

if($image_url['host'] == 'www.youtube.com' ||

$image_url['host'] == 'youtube.com'){

$array = explode("&", $image_url['query']);

return "http://img.youtube.com/vi/".substr($array[0], 2)."/0.jpg";

}else if($image_url['host'] == 'www.youtu.be' ||

$image_url['host'] == 'youtu.be'){

$array = explode("/", $image_url['path']);

return "http://img.youtube.com/vi/".$array[1]."/0.jpg";

}else if($image_url['host'] == 'www.vimeo.com' ||

$image_url['host'] == 'vimeo.com'){

$hash = unserialize(file_get_contents("http://vimeo.com/api/v2/video/".

substr($image_url['path'], 1).".php"));

return $hash[0]["thumbnail_medium"];

}

}

<img src="<?php echo video_image('youtube URL'); ?>" />
