1）用composer 下载短信云SDK，

composer require "qcloudsms/qcloudsms_php"

会得到

2）配置短信参数信息

<?php

return [

    'app_id'      => '1400009099',

    'app_key'     => '61f38*************7ec7b6',

    'sms_sign'    => '23**19',

    'template_id' => '35**46',

];

3）引入

use Qcloud\Sms\SmsSingleSender;

4）

//读取config/sms.php配置信息
$config = #sms.php配置信息
$sender = new SmsSingleSender($config['app_id'],$config['app_key']);
$result = $sender->sendWithParam("86", $phone,
    $config['template_id'],$code, $config['sms_sign'], "", "");
$rsp = json_decode($result);

5注意 $code 须是数组 ，否则会报

 {"result":1014,"errmsg":"package format error, template params error","ext":""}
