项目用到临时写的。待完善：

代码如下:

/*

* 根据用户提交的(swf/html)地址，获取优酷，土豆的swf播放地址

* */

private function _getswf ($url = '') {

if(isset($url) && !empty($url)){

preg_match_all('/http:\/\/(.*?)?\.(.*?)?\.com\/(.*)/',$url,$types);

}else{

return false;

}

$type = $types[2][0];

$domain = $types[1][0];

$isswf = strpos($types[3][0], 'v.swf') === false ? false : true;

$method = substr($types[3][0],0,1);

switch ($type){

case 'youku' :

if( $domain == 'player' ) {

$swf = $url;

}else if( $domain == 'v' ) {

preg_match_all('/http:\/\/v\.youku\.com\/v_show\/id_(.*)?\.html/',$url,$url_array);

$swf = 'http://player.youku.com/player.php/sid/'.str_replace('/','',$url_array[1][0]).'/v.swf';

}else{

$swf = $url;

}

break;

case 'tudou' :

if($isswf){

$swf = $url;

}else{

$method = $method == 'p' ? 'v' : $method ;

preg_match_all('/http:\/\/www.tudou\.com\/(.*)?\/(.*)?/',$url,$url_array);

$str_arr = explode('/',$url_array[1][0]);

$count = count($str_arr);

if($count == 1) {

$id = explode('.',$url_array[2][0])[0];

}else if($count == 2){

$id = $str_arr[1];

}else if($count == 3){

$id = $str_arr[2];

}

$swf = 'http://www.tudou.com/'.$method.'/'.$id.'/v.swf';

}

break;

default :

$swf = $url;

break;

}

return $swf;

}
