This article describes the application method of PHP memcache on the WeChat public platform. Share it with everyone for your reference, the details are as follows:

Now most interactions on the WeChat public platform are users sending messages -> WeChat analyzes and returns the results. This mode has a relatively single function. Here is another interactive mode: the user sends information ->WeChat analyzes the information and prompts the next step ->the user sends information->....->WeChat returns the results. This article introduces the use of memcache in sae to implement the above mode.

Idea:

1. When the user sends a message, WeChat will record the user’s unique openid and assign its value to $fromUsername.

2. Use memcache to save two data, one is the last message sent by the user, and the other is a randomly defined value (1 in the example) for judging user actions.

3. Use $fromUsername as key positioning.

The sample code is as follows:


FromUserName; $toUsername = $postObj->ToUserName; $keyword = trim($postObj->Content); $time = time(); $textTpl = "   %s   0 "; //定义变量last_step,记录上一次动作 $last_step=$mc->get($fromUsername."step"); //定义变量last_data,记录上一次数据 $last_data=$mc->get($fromUsername."data"); if(!empty( $keyword )){ //判断用户动作 if($last_step!=1){ //将用户输入的数据保存至memcache $mc->set($fromUsername."data",$keyword,0,120); //记录用户这一次动作,值设为1 $mc->set($fromUsername."step",1,0,120); $msgType = "text"; $contentStr = "请再输入一个值:"; $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr); echo $resultStr; } else { //清空memcach动作 $mc->delete($fromUsername."step"); //清空memcach数据 $mc->delete($fromUsername."data"); $msgType = "text"; $contentStr = "你输入的第一个值为:".$last_data."\n 第二个值为:".$keyword; $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr); echo $resultStr; } } } else { echo ""; } ?>
