PHP method to implement SMS verification code function through SMS platform

With the increasing popularity of mobile Internet and mobile phones, SMS verification codes have become an important means of security verification. During website registration, login, password retrieval and other operations, users often need to enter the received SMS verification code to complete the operation. Today we will introduce in detail how to use PHP to implement the SMS verification code function through the SMS platform.

1. Select an SMS platform

Before activating the PHP SMS verification code function, you first need to choose an SMS platform. There are many SMS platforms on the market to choose from, such as YimeiSoftStone, Ronglian Cloud Communications, Yunpian.com, etc. When choosing a platform, you need to consider the following factors:

1. Stability

The stability of the SMS platform is very important. If problems such as failure to send SMS messages and delays often occur, It will bring a very bad experience to users and even affect the user experience.

2. Price

The prices of different SMS platforms vary greatly, and you need to choose according to your own needs and budget. Generally speaking, platforms with their own independent SMS sending channels are more expensive, but their stability and sending success rate are often higher.

3. Supported functions

Different SMS platforms support different functions. Some platforms can provide powerful API interfaces, which can easily implement SMS verification codes and marketing SMS. , voice verification code and other functions, some platforms only provide a simple SMS sending interface.

When choosing a text messaging platform, you need to consider the above factors based on your actual situation and choose a platform that suits you.

2. Register an account and obtain an API key

After selecting an SMS platform, you need to register an account on the platform and obtain an API key, which can be used to call the platform in PHP code. Interface.

In the process of registering an account, you need to provide relevant company information, such as company name, certificates, etc. Then you need to verify the SMS verification code or use other methods for identity authentication to complete account registration.

After completing the account registration, you need to create the corresponding application on the platform. During the process of creating the application, you generally need to provide the application name, application description, SMS signature and other information, and you need to apply to obtain the API key in the background. .

3. Call the SMS sending interface in the background

After obtaining the API key, you can write PHP code in the background and call the interface provided by the SMS platform to implement the SMS verification code sending function. Taking Yunpian.com as an example, the following is the specific implementation method:

1. Install PHP CURL library

PHP needs to use the CURL library to send HTTP requests. If it is not installed Need to install first.

2. Write a function to send SMS verification code

Write a function to send SMS verification code and encapsulate it into a class to facilitate reuse in the program. The following is a sample code:

<?php

class SmsHelper{
  private static $apiUrl = 'https://sms.yunpian.com/v2/sms/single_send.json'; //短信发送接口地址
  private static $apiKey = 'xxxx'; //API 密钥，需要替换成自己的

  /**
   * 发送短信验证码
   * @param $mobile 手机号码
   * @param $code   验证码
   * @return bool
   */
  public static function sendVerifyCode($mobile, $code){
    $postData = [
      'apikey' => self::$apiKey,
      'mobile' => $mobile,
      'text'   => '【签名】您的验证码是'.$code.'。'
    ];

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, self::$apiUrl);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept:text/plain;charset=utf-8', 'Content-Type:application/x-www-form-urlencoded', 'charset=utf-8'));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postData, '', '&'));
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); //不校验 SSL 证书
    $result = curl_exec($ch);
    $error = curl_error($ch);
    curl_close($ch);
    if($result === false || !empty($error)) return false;

    $json = @json_decode($result, true);
    if(!is_array($json)) return false;

    return !empty($json['code']) && $json['code'] == 0;
  }
}

$apiUrl and $apiKey in the code are the SMS sending interface address and API key provided by the SMS platform respectively, and need to be replaced with the values ​​provided by your own platform. In the function that sends SMS verification code, two parameters, mobile phone number and verification code, need to be passed in. Returns true if successful and false if failed.

4. Implement the verification code function on the front-end page

After calling the API of the SMS platform through the background to send the SMS verification code, you also need to call the background interface on the front-end page to complete the sending and verification of the verification code. test.

The way to send the verification code is generally to submit the mobile phone number on the page, and call the function written above to send the SMS verification code in the background to send the verification code. Verification code verification can be implemented on the page. After the user enters the verification code, the background interface is called through AJAX for verification and corresponding prompt information is given.

When verifying the verification code, you need to pay attention to preventing malicious swiping and limiting the number of errors. You can prevent this by setting the validity time of the SMS verification code, the maximum number of verification codes sent in a single time, and IP access limit.

5. Summary

Through the introduction of this article, we have learned in detail how to use PHP to implement the SMS verification code function through the SMS platform. Of course, this is just one implementation method, and there are other options to choose from, such as using SMS SDK, calling SMS gateway, etc. In actual projects, you need to comprehensively consider the actual needs and budget to choose a solution that suits you.
