我尝试了很多不同的解决方案。我刚接触 php 1 周，12 年前使用 ASP，所以我希望能得到一些帮助。
这里一切都运转良好。但是数据库中有大约 1000 行，我需要将它们分成页面。
<?php
$con = mysqli_connect("localhost","test","test","test")or die('could not connect to database');
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
echo "<table border='0'>
<tr>
<th>Img:</th>
<th>Text:</th>
</tr>";
$result = mysqli_query($con,"SELECT Jokes.ID, Categories.CategoryName, Jokes.CategoryID, Jokes.JokeText FROM Jokes LEFT JOIN Categories ON Jokes.CategoryID = Categories.ID ORDER BY Jokes.JokeText");
while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td align='center'><img src='webimg/" . $row['CategoryName'] . ".png' height='35' width='35'></td>";
echo "<td align='left' width='80%'>" . $row['JokeText'] . "</td>";
echo "</tr>";
}
echo "</table>";
mysql_close($con);
?>
亲切的问候。
您可以使用 MySQL
LIMIT我曾经这样做过：
获取你正在分页的总行数，并有一个类似URL中的参数，即“/p/5”或?page=5（我将使用这个作为参考，更容易编写代码并让你理解）对于页码5、也做一个故障保护，像这样：
假设每页有 10 条记录：
$page = isset($_GET['page']) ? (int) $_GET['page'] : 1;
$records_per_page = 10;
而且，在你的 SQL 中你将会有这样的东西
$start = ($page-1) * $records_per_page;
$result = mysql_query("select * from table limit {$start}, {$records_per_page}");
有点粗糙，但你应该明白要点并走在正确的道路上。
要建立分页链接...这完全取决于您。您应该先通过“从表中选择计数（PRIMARY_KEY）”查询获得行总数，以便您可以计算最大页数。
你要找的是mysql的
LIMIT使用方法非常简单。
例如：
"SELECT * FROM tablename LIMIT 3"
这将为您提供前三个结果。
在您的情况下，您需要一个偏移量，取决于当前页面：
"SELECT * FROM tablename LIMIT offset,results"
偏移量是可以计算的，取决于您想要每页有多少结果。
"SELECT * FROM tablename LIMIT 20,10"
这将显示 10 个结果，从结果 20 开始。如果您想要每个站点 10 个结果，这可能适用于 3. 站点。
<?php
$per_page = 10; //no. of results to display in one page
$pages_query = mysql_query("SELECT COUNT('id') FROM JOKES");//Or whatever field. this is just to check the number of results.
$pages = ceil(mysql_result($pages_query, 0) / $per_page);//to get the total no. of pages that will be there. For example if u have 60 results than no. og pages will be 60/10=6
$page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;// if the page variable in your url is set that means that u have clicked a page number. So it will be taking that page number and displaying those results
$start = ($page - 1) * $per_page;//to get the starting result of that page. If you are in say 6th page, then the starting element would be 6-1*10=50. This makes sure that the results in the previous pages are not displayed
$query = mysql_query("SELECT * FROM JOKES LIMIT $start, $per_page");//set the limit of results that page
while($query_row = mysql_fetch_assoc($query)){
echo " ur table names ";
}
$prev = $page - 1;//to set the prev page variable
$next = $page + 1;//to set the next page variable
if(!($page<=1)){
echo "<a href='Yourpagename.php?page=$prev'>Prev</a> ";
}//does not displays the prev variable if you are already one first page
if($pages>=1 && $page<=$pages){
for($x=1;$x<=$pages;$x++){
echo ($x == $page) ? '<strong><a href="?page='.$x.'">'.$x.'</a></strong> ' : '<a href="?page='.$x.'">'.$x.'</a> ';
}//display all the pages. Display the current page as bold
}
if(!($page>=$pages)){
echo "<a href='Your page name.php?page=$next'>Next</a>";
}//do not display next vvariable if your are in the last page

谢谢所有的答案。我学习了这个教程并且它起作用了：http://www.developphp.com/view.php?tid=1349
