php连接记录代码

<?php
try {
    // 数据库连接配置
    $host = 'localhost';
    $dbname = 'mydatabase';
    $user = 'myuser';
    $password = 'mypassword';

    // 创建PDO实例
    $pdo = new PDO("mysql:host=$host;dbname=$dbname;charset=utf8", $user, $password);

    // 设置错误模式为异常
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    // 执行查询
    $stmt = $pdo->query('SELECT * FROM users');
    $users = $stmt->fetchAll(PDO::FETCH_ASSOC);

    // 输出结果
    foreach ($users as $user) {
        echo "ID: " . $user['id'] . " - Name: " . $user['name'] . "<br>";
    }
} catch (PDOException $e) {
    echo "Connection failed: " . $e->getMessage();
}
