我想使用SMS Gateway PHP API，但我没有成功使用它。我用安卓从SMSGATEWAY下载了该软件。我和我创建了一个帐户。我还有一个免费的网络服务器，我上传了两个文档：
他们的PHP API库"smsGateway.php"，人们可以在这里找到：https://smsgateway.me/sms-api-libraries/sms-gateway-me-php.zip
我的文件"测试.php"：
<?php
include "smsGateway.php";
$smsGateway = new SmsGateway('my_email_on_their_website', 'my_password_for_this_account');
$deviceID = 111111; //the number of my device, displayed on their website or on the software installed on my phone
$number = '+1234567891'; //the number I want to SMS
$message = 'Hello World!'; //my message
$options = [
'send_at' => strtotime('+10 minutes'), // Send the message in 10 minutes
'expires_at' => strtotime('+1 hour') // Cancel the message in 1 hour if the message is not yet sent
];
//Please note options is no required and can be left out
$result = $smsGateway->sendMessageToNumber($number, $message, $deviceID, $options);
?>
但是当我使用浏览器 http://mywwebsite.com/test.php 访问时，它不发送短信，你知道为什么吗？你能帮我解决这个问题吗？（我手机上的网关仍处于活动状态）。
提前谢谢你！
此致敬意
你的代码是正确的。如果要显示结果，请在变量后写$result行
echo json_encode($result);
所以你的代码将看起来像这样
<?php
include "smsGateway.php";
$smsGateway = new SmsGateway('my_email_on_their_website', 'my_password_for_this_account');
$deviceID = 111111; //the number of my device, displayed on their website or on the software installed on my phone
$number = '+1234567891'; //the number I want to SMS
$message = 'Hello World!'; //my message
$options = [
'send_at' => strtotime('+10 minutes'), // Send the message in 10 minutes
'expires_at' => strtotime('+1 hour') // Cancel the message in 1 hour if the message is not yet sent
];
//Please note options is no required and can be left out
$result = $smsGateway->sendMessageToNumber($number, $message, $deviceID, $options);
echo json_encode($result);
?>
