实例代码如下：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>用户列表</title>
</head>
<body>
<?php
$con = mysqli_connect("localhost","root","");
mysqli_query("set names utf8"); mysqli_select_db("zhiye",$con);
$pageSize = 1; //每页显示的数量
$rowCount = 0; //要从数据库中获取
$pageNow = 1; //当前显示第几页
//如果有pageNow就使用，没有就默认第一页。
if (!empty($_GET['pageNow'])){
$pageNow = $_GET['pageNow'];
}
$pageCount = 0; //表示共有多少页
$sql1 = "select count(id) from user";
$res1 = mysqli_query($sql1);
if($row1=mysqli_fetch_row($res1)){
$rowCount = $row1[0];
}
//计算共有多少页，ceil取进1
$pageCount = ceil(($rowCount/$pageSize));
//使用sql语句时，注意有些变量应取出赋值。
$pre = ($pageNow-1)*$pageSize;
$sql2 = "select * from user limit $pre,$pageSize";
$res2 = mysqli_query($sql2);
while($row=mysqli_fetch_assoc($res2)){
echo $row['user_name']."<br>";
echo $row['name']."<br>";
echo $row['email']."<br>";
echo $row['password']."<br>";
echo $row['tel']."<br>";
}
for ($i=1;$i<=$pageCount;$i++){
echo "<a href='userList.php?pageNow=$i'>$i</a> ";
}?>
</body>
</html>当有大量数据时，就不能使用上述方法
<?php
$con = mysqli_connect("localhost","root","");
mysqli_query("set names utf8");
mysqli_select_db("zhiye",$con);
$pageSize = 1; //每页显示的数量
$rowCount = 0; //要从数据库中获取
$pageNow = 1; //当前显示第几页
//如果有pageNow就使用，没有就默认第一页。
if (!empty($_GET['pageNow'])){
$pageNow = $_GET['pageNow'];
}
$pageCount = 0; //表示共有多少页
$sql1 = "select count(id) from user";
$res1 = mysqli_query($sql1);
if($row1=mysqli_fetch_row($res1)){
$rowCount = $row1[0];
}
//计算共有多少页，ceil取进1
$pageCount = ceil(($rowCount/$pageSize));
//使用sql语句时，注意有些变量应取出赋值。
$pre = ($pageNow-1)*$pageSize;
$sql2 = "select * from user limit $pre,$pageSize";
$res2 = mysqli_query($sql2);
//$sql = "select * from user";
//$res = mysqli_query($sql,$con);
while($row=mysqli_fetch_assoc($res2)){
echo $row['user_name']."<br>";
echo $row['name']."<br>";
echo $row['email']."<br>";
echo $row['password']."<br>";
echo $row['tel']."<br>";
}
if($pageNow>1){
$prePage = $pageNow-1;
echo "<a href='userList.php?pageNow=$prePage'>pre</a> ";
}
if($pageNow<$pageCount){
$nextPage = $pageNow+1;
echo "<a href='userList.php?pageNow=$nextPage'>next</a> ";
echo "当前页{$pageNow}/共{$pageCount}页";
}
echo "<br/><br/>";
?>
<form action="userList.php">
<input type="text" name="pageNow">
<input type="submit" value="GO">
</form>更过相关问题请访问PHP中文网：PHP视频教程
