Steps to implement the SMS verification code function in PHP Developer City

With the rapid development of the mobile Internet, shopping behavior has gradually shifted from traditional offline to online. In order to ensure the security of users' accounts, the SMS verification code function in mall development has become particularly important. This article will introduce the steps to implement the mobile phone SMS verification code function in the PHP Developer City.

1. Choose a suitable SMS service provider
   First of all, we need to choose a reliable SMS service provider. There are many SMS service providers on the market to choose from, such as Alibaba Cloud SMS, Tencent Cloud SMS, etc. According to your own needs, choose a reasonably priced, stable and reliable SMS service provider for access.
2. Register SMS service and obtain API interface information
   Register and log in to the official website of the selected SMS service provider, complete the registration of the developer account and log in. Then, find information related to the SMS API in the developer background, including API interface address, application key, etc. Record this information to provide support for subsequent code integration.
3. Writing the code for sending text messages
   In the PHP mall development project, we need to write the code for sending text messages. First, we need to use PHP's curl extension library to send an HTTP request to call the SMS service provider's API interface.

First, introduce the curl extension library into the code:

<?php
// 引入curl扩展库
$ch = curl_init();

Then, set the request address and parameters of the SMS API:

$url = '短信API接口地址';
$params = array(
    'accessKeyId' => '应用ID',
    'accessKeySecret' => '应用密钥',
    'mobile' => '手机号码',
    'templateCode' => '短信模板编码',
    'templateParam' => json_encode(array(
        'code' => '验证码'
    ))
);

Next, set the request options And send the POST request:

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($params));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);

Finally, process the SMS sending result and close the curl connection:

if ($response === false) {
    // 短信发送失败的处理逻辑
} else {
    $result = json_decode($response, true);
    if ($result['Code'] === 'OK') {
        // 短信发送成功的处理逻辑
    } else {
        // 短信发送失败的处理逻辑
    }
}

curl_close($ch);

4. Verify SMS verification code
   When the user registers or logs in, the user needs to be verified Enter the SMS verification code. After receiving the verification code submitted by the user, we need to verify with the backend of the SMS service provider.

First, we need to call the API interface of the SMS service provider again and send the verification code and mobile phone number submitted by the user to the background as parameters.

Then, process the SMS verification code verification results, and perform corresponding business logic processing based on the verification results.

5. Add the call and display of the SMS verification code function
   Finally, add the call and display of the SMS verification code function in the registration and login pages of the mall.

After the user enters the mobile phone number, click the Get Verification Code button and call the code for sending SMS to send the verification code.

When the user submits the form, verify the SMS verification code entered by the user. If the verification passes, continue with subsequent business logic, otherwise an error message will be returned.

Through the above steps, we can implement the mobile phone SMS verification code function in the mall project developed by PHP. This can improve user account security, prevent malicious registration and login behaviors, and ensure the normal operation of the mall.
