How to add mobile phone verification function in PHP for user registration

In today's online world, mobile phone verification has become a very important security measure, especially in During user registration. Adding mobile phone verification function can prevent malicious registration and protect the security of user accounts. This article will introduce how to implement the mobile phone verification function in PHP and apply it to user registration.

1. Collect and verify user mobile phone numbers

1. First, we need to add an input box to the user registration form to fill in the user’s mobile phone number.

<input type="text" name="phone" placeholder="请输入手机号码">

2. On the server side, we need to verify the mobile phone number entered by the user to ensure that it is in the correct format. You can use regular expressions to match the format of mobile phone numbers.

$phone = $_POST['phone'];

// 判断手机号码格式是否正确
if(!preg_match('/^1[34578]d{9}$/', $phone)){
    echo '手机号码格式不正确';
    exit;
}

2. Send the verification code to the user’s mobile phone

1. We can use the SMS service provider’s API to send the verification code to the user’s mobile phone. Here we take Alibaba Cloud SMS service as an example, assuming that we already have AccessKey and AccessSecret.

require 'aliyun-php-sdk-core/Config.php';    // 引入阿里云SDK的配置文件

$accessKeyId = '<yourAccessKeyId>';    // 替换成你自己的AccessKeyId
$accessSecret = '<yourAccessSecret>';  // 替换成你自己的AccessSecret

use AliyunCoreConfig;

// 设置阿里云短信服务的AccessKey和AccessSecret
Config::load();

$acsClient = new AliyunCoreDefaultAcsClient([
    'RegionId' => 'cn-hangzhou',    // 设置短信服务的区域，这里是杭州
    'AccessKeyId' => $accessKeyId,
    'AccessKeySecret' => $accessSecret
]);

// 发送短信验证码
function sendVerificationCode($phone, $code){
    $request = new AliyunApiSmsRequestV20170525SingleSendSmsRequest();
    $request->setSignName('云市场');    // 设置短信签名
    $request->setTemplateCode('SMS_12345678');    // 设置短信模板ID
    $request->setRecNum($phone);    // 设置接收短信的手机号码
    $request->setParamString('{"code":"' . $code . '"}');    // 设置短信模板中的参数

    try {
        $response = $acsClient->getAcsResponse($request);
        // 处理短信发送结果
        if ($response->Code == 'OK') {
            return true;
        } else {
            return false;
        }
    } catch (AliyunCoreExceptionClientException $e) {
        return false;
    } catch (AliyunCoreExceptionServerException $e) {
        return false;
    }
}

// 生成随机验证码
function generateVerificationCode($length = 6){
    $code = '';
    $characters = '0123456789';
    $charLength = strlen($characters) - 1;
    for ($i = 0; $i < $length; $i++){
        $code .= $characters[rand(0, $charLength)];
    }

    return $code;
}

// 发送验证码到用户手机
$verificationCode = generateVerificationCode();
if(!sendVerificationCode($phone, $verificationCode)){
    echo '短信验证码发送失败';
    exit;
}

3. Verify the verification code entered by the user

1. When the user submits the registration form, we need to verify whether the verification code entered by the user is correct.

$verifyCode = $_POST['verifyCode'];

// 判断用户输入的验证码是否正确
if($verifyCode != $verificationCode){
    echo '验证码错误';
    exit;
}

At this point, we have completed the process of adding mobile phone verification function in PHP for user registration. In this way, malicious registration can be effectively prevented and the security of user accounts can be improved.

It should be noted that the above code is only a simple example. In actual application, the code needs to be processed in more detail, and you need to apply for an account with the Alibaba Cloud SMS service provider and configure SMS templates and other information. .
