请问这段代码哪里有错？

 $newsArr = array(         array("Title"=>"this is first item",            "Description"=>"this is first item description",            "PicUrl"=>"http://img4.imgtn.bdimg.com/it/u=2943793272,3641314298&fm=21&gp=0.jpg",            "Url"=>"http://www.baidu.com"         ),         array("Title"=>"this is second item",             "Description"=>"this is second item description",             "PicUrl"=>"http://img2.imgtn.bdimg.com/it/u=945726929,542696667&fm=21&gp=0.jpg",             "Url"=>"http://www.baidu.com"         ),         array("Title"=>"this is thired",            "Description"=>"this is thired",            "PicUrl"=>"http://img1.imgtn.bdimg.com/it/u=2783016379,35786742&fm=21&gp=0.jpg",            "Url"=>"http://www.baidu.com"         ));foreach ($newsArr as $key => $value) {   $itemstr .= "         
";}   $result = "%s".count($newsArr)."".$itemstr."";   $newsInfo = sprintf($result, $fromUser , $toUser , time());   echo $newsInfo;
