How to use PHP to implement the image and text message push function of public accounts

With the popularity of WeChat public accounts, more and more individuals and companies have begun to pay attention to how to push through Public accounts to disseminate information and promote products. Among them, graphic messages are a very effective way. This article will introduce how to use the PHP language to implement the push function of graphic and text messages on public accounts, and give specific code examples.

  1. Preparation

Before starting to write code, we need to prepare the following:

  • A WeChat public account, which can be found on WeChat Obtained by registering on the public platform.
  • Create a custom menu on the WeChat public platform and configure the corresponding jump link.
  • A usable PHP development environment.
  1. Get access_token

Before using the API of the WeChat public account, we need to obtain an access_token first. This token is the credential used for subsequent operations. . Access_token can be obtained through the following code:

function getAccessToken($appId, $appSecret) {
    $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$appId."&secret=".$appSecret;
    $result = file_get_contents($url);
    $result = json_decode($result, true);
    return $result['access_token'];
}

$appId = "your_app_id";
$appSecret = "your_app_secret";
$accessToken = getAccessToken($appId, $appSecret);

Replace your_app_id and your_app_secret in the above code with your actual values.

  1. Constructing a graphic message

Before pushing a graphic message, we need to construct a graphic message. Here we use an array to represent a graphic message, which can include title, description, jump link, image link and other information. The following is an example:

$articles = array(
    array(
        'title' => "图文消息标题1",
        'description' => "图文消息描述1",
        'url' => "http://example.com/article1",
        'picurl' => "http://example.com/article1.jpg"
    ),
    array(
        'title' => "图文消息标题2",
        'description' => "图文消息描述2",
        'url' => "http://example.com/article2",
        'picurl' => "http://example.com/article2.jpg"
    ),
);

You can add more graphic and text messages as needed, and each message is represented by an array element.

  1. Push graphic and text messages

With access_token and graphic messages, we can use the Group sending interface of the WeChat official account to push graphic and text messages information. The following is a sample code:

function sendArticles($accessToken, $articles) {
    $url = "https://api.weixin.qq.com/cgi-bin/message/mass/send?access_token=".$accessToken;
    $data = array(
        'touser' => "@all",
        'msgtype' => "news",
        'news' => array('articles' => $articles)
    );
    $jsonData = json_encode($data);
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonData);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $response = curl_exec($ch);
    curl_close($ch);
    return $response;
}

$response = sendArticles($accessToken, $articles);

Replace $accessToken in the above code with the previously obtained access_token, $articles is the constructed image and text message array .

  1. Conclusion

Through the above steps, we can use PHP to implement the image and text message push function of the official account. When we call the sendArticles function, a graphic message will be sent to all users who follow the official account. It should be noted that there is a limit to the number of pushes to a user per day.

I hope this article can help readers better use PHP to implement the image and text message push function of public accounts, and achieve better public account operation effects.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
