PHP implements batch sending and verification methods of SMS verification codes

In modern society, SMS verification codes have become a commonly used means of identity verification. Whether you are registering a new user, changing your password, or performing important operations, SMS verification codes are one of the key links to ensure security. In order to improve user experience and reduce development costs, we can implement batch sending and verification methods of SMS verification codes through PHP. This article will introduce the specific implementation steps and provide detailed code examples.

1. Preparation
Before implementing batch sending and verification of SMS verification codes, we need to first configure an interface of an SMS service provider. Common SMS service providers include Alibaba Cloud, Rongyun, etc. Choose an applicable service provider according to your needs and obtain its API key. In this article, we take Alibaba Cloud as an example.

2. Implement batch sending of SMS verification codes

1. Introduce Alibaba Cloud SMS SDK

require_once 'aliyun-php -sdk-core/Config.php';
require_once 'Dysmsapi/Request/V20170525/SendSmsRequest.php';

2. Set Alibaba Cloud SMS API key

$accessKeyId = "your_access_key_id";
$accessKeySecret = "your_access_key_secret";

3. Create a SendSmsRequest instance and set the parameters

$signName = "Your SMS signature ";
$templateCode = "Your SMS template code";
$templateParam = json_encode(["code"=>"123456"]); // Convert template parameters to Json format through json_encode

$request = new DysmsapiRequestV20170525SendSmsRequest();
$request->setPhoneNumbers("18888888888"); // Set the mobile phone number, you can fill in multiple numbers
$request->setSignName($signName );
$request->setTemplateCode($templateCode);
$request->setTemplateParam($templateParam);

4. Send SMS

try {

$response = DysmsapiRequestV20170525SendSmsRequest::sendRequest($accessKeyId, $accessKeySecret, $request);
print_r($response);

} catch (Exception $e) {

echo "发送短信失败：" . $e->getMessage();

}

The above code can send SMS verification codes to a single or multiple mobile phone numbers. Just pass the mobile phone number and verification code to the Alibaba Cloud interface as part of the template parameters.

3. Implement SMS verification code verification

1. Receive the user’s verification code

$userCode = $_POST['code']; // Assume that the verification code submitted by the user is transmitted through POST, obtained here and saved as the $userCode variable.

2. Verify the user's verification code

$serverCode = "123456"; // Assume that the verification code saved by the server is a fixed value of 123456, and save it here as $serverCode variable.

if ($userCode == $serverCode) {

echo "验证码验证通过";

} else {

echo "验证码验证失败";

}

The above code performs the verification code submitted by the user and A simple comparison of the verification codes saved by the server. If the two are consistent, the verification is passed, otherwise the verification fails.

Summary
The batch sending and verification method of SMS verification codes is implemented through PHP, which can easily provide user registration, login, and operation security and protect user privacy. In the specific implementation process, we need to configure an interface of an SMS service provider, such as Alibaba Cloud, and use the API provided by it to send SMS messages. At the same time, it is also necessary to simply compare the verification code submitted by the user with the verification code saved by the server to verify its validity.

The above is my introduction to the specific steps and code examples of the batch sending and verification method of SMS verification codes in PHP. I hope to be helpful!
