How to use PHP to develop the keyword reply function of public accounts
With the rapid development of social media, WeChat public accounts have become a way for enterprises, institutions and individuals to spread information One of the important channels. In order to improve user experience and be able to reply to users' messages in a timely manner, it is very important to develop the keyword reply function of public accounts. This article will introduce how to use PHP to develop the keyword reply function of public accounts and provide specific code examples.
1. Create a public account
First, we need to create a public account on the WeChat public platform. After registering and binding the official account, obtain your AppID and AppSecret in the Developer Center. This information will be used in subsequent development.
2. Obtain access_token
Before using the WeChat interface for development, we need to obtain the access_token, which is the credential for calling the WeChat API interface. We can obtain the access_token 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;
$result = httpGet($url);
$accessToken = json_decode($result, true)['access_token'];
return $accessToken;
}
function httpGet($url){
$curl = curl_init();
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_TIMEOUT, 500);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_URL, $url);
$result = curl_exec($curl);
curl_close($curl);
return $result;
}
$appid = "Your App ID";
$appsecret = "Your App Secret";
$accessToken = getAccessToken($appid, $appsecret);3. Monitor user messages
In the development settings of the official account, we can forward the received user messages to our own server for processing. We can use PHP to develop an interface to listen to messages sent by users and perform keyword matching and replies.
$data = file_get_contents("php://input");
$message = simplexml_load_string($data, 'SimpleXMLElement', LIBXML_NOCDATA);
$msgType = $message->MsgType;
$keyword = trim($message->Content);
$reply = "";
if ($msgType == "text") {
if ($keyword == "你好") {
$reply = "你好，歡迎關(guān)注我們的公眾號！";
} elseif ($keyword == "最新消息") {
$reply = "這里是最新消息！";
} else {
$reply = "感謝您的留言，我們會盡快回復(fù)您！";
}
}
$response = "<xml>
<ToUserName><![CDATA[" . $message->FromUserName . "]]></ToUserName>
<FromUserName><![CDATA[" . $message->ToUserName . "]]></FromUserName>
<CreateTime>" . time() . "</CreateTime>
<MsgType><![CDATA[text]]></MsgType>
<Content><![CDATA[" . $reply . "]]></Content>
</xml>";
echo $response;4. Deploy to the server
Save the above code as a PHP file and deploy it to a server that supports PHP. In the development settings of the WeChat public platform, set the URL for receiving messages to the deployed URL. In this way, when a user sends a message, the WeChat server will forward the message to our server and perform keyword matching and reply.
5. Test
After completing the above steps, we can send a message to the official account for testing. Depending on the keywords, we can get different responses.
Summary:
This article introduces how to use PHP to develop the keyword reply function of public accounts, and provides specific code examples. Through the above steps, we can monitor user messages, match keywords, and reply. Of course, we can expand more functions according to specific needs. I hope this article is helpful to everyone, thank you for reading!

Describe the SOLID principles and how they apply to PHP development.
Apr 03, 2025 am 12:04 AM
The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
