php实现超简的分页功能
代码案例来自吾爱破解论坛
效果如下：
PHP代码：
<?php
try {
$dsn = "mysql:host=localhost;dbname=数据库名";
$username = "数据库名";
$password = "数据库密码";
$pdo = new PDO($dsn, $username, $password);
} catch(PDOException $e) {
echo "Connection failed: " . $e->getMessage();
}
//计算总记录数
$total=$pdo->query('SELECT COUNT(1) FROM `表名`')->fetchColumn();
//每页显示记录数
$pageSize=10;
//计算总页数
$pageCount=ceil($total/$pageSize);
//当前页码，默认为第一页
$pageNum=isset($_GET['page']) ? $_GET['page'] : 1;
//起始记录数
$start=($pageNum-1)*$pageSize;
//查询分页数据
$sql="SELECT * FROM `表名` LIMIT {$start},{$pageSize}";
$stmt=$pdo->query($sql);
$list=$stmt->fetchAll(PDO::FETCH_ASSOC);
