php如何调用短信接口

<?php
// 短信服务提供商的API地址
$url = "https://api.smsprovider.com/send";

// API密钥
$apiKey = "your_api_key";

// 用户手机号
$phone = "13800138000";

// 验证码
$code = rand(1000, 9999);

// 请求参数
$data = array(
    'phone' => $phone,
    'code' => $code,
    'msg' => "您的验证码是：$code，请在5分钟内使用。"
);

// 初始化cURL会话
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/x-www-form-urlencoded',
    'Authorization: Bearer ' . $apiKey
));

// 执行cURL会话
$response = curl_exec($ch);

// 检查是否有错误
if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
} else {
    echo 'Response:' . $response;
}

// 关闭cURL会话
curl_close($ch);
?>
