面對分頁問題

有人可以告訴我這個分頁有什麼問題。我試圖在每10條記錄後進行分頁，但失敗。相反，我在同一時間看到所有記錄，而不是分頁。我在這裏錯了。面對分頁問題

查看用戶文件

<form action="tuser.php" method="GET"> 
<table> 
<tr> 
<td>Here You get the Table View of Data</td>  
</tr> 
<tr> 
<td><input type="submit" name="submit" value="Total Number of User"/></td> 
</tr> 
</form>

錯了，因爲什麼呢？它會出錯？ – 2014-11-21 09:59:59

沒有任何錯誤，但所有記錄都顯示在一個頁面中。有些時候我面臨未定義的索引：提交錯誤 – 2014-11-21 10:03:30

試試這個簡單的..........分頁
