php içine html kodu eklerken sorun yaşıyorum

function postParse($html,$type){

    if($type=='html'&&preg_match('/fullscreenUrl\s\=\s.*video\_id\=(.*)\&.*\&t\=(.*)\&/i',$html,$matches)){
        $thumbid_arr=explode('&',basename($matches[1]));
        $thumbid=array_shift($thumbid_arr);
        $html=preg_replace('#<div id="watch-checker-div">(.*)to.write\("watch-checker-div"\);#is','<embed src="'.optURL.'videoplayer.swf" width="480" height="395" allowscriptaccess="always" allowfullscreen="true" flashvars="height=395&width=480&file='.proxifyURL('http://youtube.com/get_video?video_id='.$matches[1].'&t='.$matches[2]).'&image='.proxifyURL('http://i.ytimg.com/vi/'.$thumbid.'/0.jpg').'&backcolor=0x000000&frontcolor=0xCCCCCC&lightcolor=0x996600&searchbar=false&type=flv" menu="false" />'.'<script type="text/javascript">',$html);

    }

    return $html;
}
