Introduction to how to use PHP to develop WeChat to receive messages, automatically judge and reply to corresponding messages

This article mainly introduces the development of the PHP version of WeChatreceiving messages, the method of automatically judging and replying to the corresponding messages, and involves the related operation skills of calling based on the WeChat message processinginterface, Friends in need can refer to

This article describes the example of the PHP version of WeChat development on how to receive messages, automatically judge and reply to corresponding messages. I share it with you for your reference. The details are as follows:

WeChat’s api is now powerful enough that you can freely call the content of our website or designated database to automatically reply and push messages, here Let me introduce you to a WeChat development note.

Send 1, 2, 3, 7 test corresponding messages, the menu mode needs to be upgraded to a service account, or the number of subscribers exceeds 500.

1. The messages sent by users are received through the developer URL submitted by you. You can get it by subscribing here. The data sent is in the xml format and needs to be parsed. The code is as follows:

$data = $GLOBALS["HTTP_RAW_POST_DATA"];
if (!emptyempty($data)) {//接收消息并处理
$xml = (array)simplexml_load_string($data, ‘SimpleXMLElement', LIBXML_NOCDATA);
return $xml;
}

The reply also needs to return XML data format.

2. Actively send messages to users, query user information, and create custom menu (subscription accounts can also be used now), As well as some advanced functions, you need to obtain the appid and AppSecret in order to obtain the access_token.

Access_token is used by every interface in addition to receiving information. The access_token expires in 7200 milliseconds and needs to be obtained again.

Currently, I have implemented it, receiving messages, automatically judging and replying to the corresponding news, creating a custom menu, and performing corresponding operations after clicking on the custom menu, such as user lists. I feel that there is no difference between the current development model and the subscription model.

Here is a test example of testing the reply, the code is as follows:

<?php
/**
 * wechat php test
 */
//define your token
define("TOKEN", "你的申请上的token");
$wechatObj = new wechatCallbackapiTest();
$wechatObj->valid();
class wechatCallbackapiTest
{
 public function valid()
  {
    $echoStr = $_GET["echostr"];
    //valid signature , option
    if($this->checkSignature()){
     $this->responseMsg();
     exit;
    }
  }
  public function responseMsg()
  {
 //get post data, May be due to the different environments
 $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
    //extract post data
 if (!emptyempty($postStr)){
        $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
        $fromUsername = $postObj->FromUserName;
        $toUsername = $postObj->ToUserName;
        $keyword = trim($postObj->Content);
        $time = time();
  $msgType = "text";
        $textTpl = "<xml>
    <ToUserName><![CDATA[%s]]></ToUserName>
    <FromUserName><![CDATA[%s]]></FromUserName>
    <CreateTime>%s</CreateTime>
    <MsgType><![CDATA[%s]]></MsgType>
    <Content><![CDATA[%s]]></Content>
    <FuncFlag>0</FuncFlag>
    </xml>";
  if(!emptyempty( $keyword ))
        {
         $contentStr = $this->keyrep($keyword);
   if( emptyempty($contentStr) )
   {
   $contentStr ="你是故意的吧，没文化真可怕";//你是故意的吧，没文化真可怕;
   }
   //$contentStr = @iconv('UTF-8','gb2312',$keyword);
         $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
         echo $resultStr;
        }else{
         $contentStr = '没文化真可怕，居然不会打字！';//$this->keyrep($keyword);
         //$contentStr = @iconv('UTF-8','gb2312',$keyword);
   $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
         echo $resultStr;
        }

     echo "";

 private function checkSignature()

 sort($tmpArr);
