我创建了一个页面，该页面应该从我的数据库中提取所有域并将它们显示在表格中。分页设置为每页显示 1002 个域，表格应为 3 列。

当我不确定该怎么做时，您可以看到“Row Test1”和“Row Test1” - 它们正确显示在页面上。但是，我该如何做到这一点，而不是显示这些，它实际上会显示我数据库中的域。

如果有人可以发布代码的固定部分的示例，将不胜感激，我觉得我一直在尝试很多事情，而且有点令人困惑。

这是整个代码：

<?php include("header.html"); ?>

<center>
<?php
    /*
        Place code to connect to your DB here.
    */
    include('database.php');    // include your code to connect to DB.

    $tbl_name="list";       //your table name
    // How many adjacent pages should be shown on each side?
    $adjacents = 3;

    /* 
       First get total number of rows in data table. 
       If you have a WHERE clause in your query, make sure you mirror it here.
    */
    $query = "SELECT COUNT(*) as num FROM $tbl_name";
    $total_pages = mysql_fetch_array(mysql_query($query));
    $total_pages = $total_pages[num];

    /* Setup vars for query. */
    $targetpage = "index.php";  //your file name  (the name of this file)
    $limit = 1002;                              //how many items to show per page
    $page = $_GET['page'];
    if($page) 
        $start = ($page - 1) * $limit;          //first item to display on this page
    else
        $start = 0;                             //if no page var is given, set start to 0

    /* Get data. */
    $sql = "SELECT website FROM $tbl_name LIMIT $start, $limit";
    $result = mysql_query($sql);

    /* Setup page vars for display. */
    if ($page == 0) $page = 1;                  //if no page var is given, default to 1.
    $prev = $page - 1;                          //previous page is page - 1
    $next = $page + 1;                          //next page is page + 1
    $lastpage = ceil($total_pages/$limit);      //lastpage is = total pages / items per page, rounded up.
    $lpm1 = $lastpage - 1;                      //last page minus 1

    /* 
        Now we apply our rules and draw the pagination object. 
        We're actually saving the code to a variable in case we want to draw it more than once.
    */
    $pagination = "";
    if($lastpage > 1)
    {   
        $pagination .= "<div class=\"pagination2\">";
        //previous button
        if ($page > 1) 
            $pagination.= "<a href=\"$targetpage?page=$prev\">&lt; previous</a>";
        else
            $pagination.= "<span class=\"disabled\">&lt; previous</span>";  

        //pages 
        if ($lastpage < 7 + ($adjacents * 2))   //not enough pages to bother breaking it up
        {   
            for ($counter = 1; $counter <= $lastpage; $counter++)
            {
                if ($counter == $page)
                    $pagination.= "<span class=\"current\">$counter</span>";
                else

            }
        }
        elseif($lastpage > 5 + ($adjacents * 2))    //enough pages to hide some
        {
            //close to beginning; only hide later pages

我有点不确定为什么你需要在你的 while 语句中分割你的行打印。只要语句评估为真，while 语句将打印出所有结果，无论是 1、20 还是无。

<?php
    $i = 0;
    echo '<table><tr>';
    while($row = mysql_fetch_array($result)) {
        $i ++;
        echo '<td><div>'.$row[databasecolumnnamethatcontainsurlgoeshere].'</div></td>';
    }  
    echo '</tr></table>';
?>
