mysql LIMIT關鍵字分頁工作不起作用

-5

我想檢查頁數後，使用LIMIT關鍵字在SELECT語句中使用LIMIT關鍵字進行分頁，我已經使用了2個循環，FOR循環用於標題，WHILE循環用於結果行，並限制使用LIMIT，需要知道，如果我可以在LIMIT關鍵字後使用變量。我的代碼如下：mysql LIMIT關鍵字分頁工作不起作用

<?php 
    include 'dbconnect.php'; 

    ?> 

    //--CHECKING number of records from STOCK table------------------------------------ 
    $di=mysql_query("SELECT * FROM CYLSTOCK_draft WHERE (DC_Date BETWEEN '$startdat' AND '$enddat' AND Ac_code='$custno' AND Product_Desc='$gas') OR (Ecr_dt BETWEEN '$startdat' AND '$enddat' AND Ac_code='$custno' AND Product_Desc='$gas') ORDER BY DC_Date"); 

    $numrows=mysql_num_rows($di); 

    // number of rows to show per page 
    $rowsperpage = 30; 
    // find out total pages 
    $totalpages = ceil($numrows/$rowsperpage); 

    if ($numrows>0) 
    { 
     $sn=0; 
     //--------for loop for Paging------------- 
     for ($x=0; $x < $totalpages; $x++) 
     { 
      echo "<br><table width='622' border='1' cellspacing='0' cellpadding='5' align='center'>"; 
      echo "<tr>"; 
      echo "<td width='30' align='center' class='toprow'>SNo.</td>";

你把'$ sn'變種成'LIMIT'在那一刻這個變種等於'0'。 – Serjio 2012-08-15 10:50:16

您也可以在打開它後立即關閉您的PHP代碼。發現格式化您的代碼時。 – Fluffeh 2012-08-15 10:52:33

它只是一段代碼因此關閉？>丟失了！謝謝 – user1114409 2012-08-15 11:12:00

.. LIMIT '$sn', 30"); ..

約$ SN沒有引號
