PHP调用创蓝短信接口实现群发短信

<?php

// 创蓝短信接口URL
$sendSmsUrl = 'http://smssh1.253.com/msg/send/json';

// 创蓝短信接口账号
$account = 'your_account';

// 创蓝短信接口密码
$password = 'your_password';

// 短信内容
$content = '【签名】您的验证码是123456';

// 手机号码列表，一次发送最多支持1000个号码
$phoneList = array('13812345678', '13912345678');

// 请求参数
$params = array(
    'account' => $account,
    'password' => $password,
    'msg' => $content,
    'phone' => implode(',', $phoneList),
);

// 发送HTTP请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $sendSmsUrl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($params));
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json; charset=utf-8'));
$result = curl_exec($ch);
curl_close($ch);

// 处理返回结果
$result = json_decode($result, true);
if ($result['code'] == '0') {
    echo '发送成功';
} else {
    echo '发送失败，错误码为：' . $result['code'];
}
