项目用到临时写的。待完善：
复制代码 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{

                }
                break;
            case 'tudou' :
