最近寫一個用戶背單字的程式碼，為每個用戶分配單字列表，在分頁時出了點問題，主要是$datas[]這段程式碼有問題，還請指點一二

#if(isset($_SESSION["username"]))
   $name=$_SESSION["username"];

$results=mysql_query("select * from study_progress where nickname='$namename ' and status='0' limit {$start},{$pageSize}");
   while ($rows= mysql_fetch_array($results)){
       $datas[]=array("enword"=array("enword"=)> ;$rows['word']);
       $word=$rows['word'];
       $result = mysql_query("select * from words group by enword where ensql_query("select * from words group by enword where ensql=word en");
       $row=mysql_fetch_array($result);
       $datas[]=array( "chword" => $row['chword'], "uk" => $row['uk'], $row['uk'] "uk_m" => $row['uk_m'], "us" => $row['us'], "us_m" => $row['us_m'], "p_content" => $row ['p_content'], "p_meaning" => $row['p_meaning'], "content" => $row['content'], "meaning" => $row['meaning'], "count " => $count);
   }

echo json_encode($datas);
