php 获取动态数据

<?php
// 数据库连接配置
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

try {
    // 创建PDO连接
    $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
    // 设置PDO错误模式为异常
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    // 查询语句
    $stmt = $conn->prepare("SELECT id, name FROM users WHERE active = :active");
    $stmt->bindParam(':active', $active, PDO::PARAM_INT);
    $active = 1;
    $stmt->execute();

    // 获取结果集
    $result = $stmt->fetchAll(PDO::FETCH_ASSOC);

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

// 关闭连接
$conn = null;
?>

<?php
$url = "https://api.example.com/data";

// 初始化cURL会话
$ch = curl_init();

// 设置cURL选项
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// 执行cURL会话并获取结果
$result = curl_exec($ch);

// 检查是否有错误发生
if(curl_errno($ch)){
    echo 'cURL Error: ' . curl_error($ch);
}

// 关闭cURL会话
curl_close($ch);

// 解析JSON数据
$data = json_decode($result, true);

// 输出结果
