Just parse json directly.

<?php
$wechatObj = new wechatappmsg();
$wechatObj->getappmsg(&#39;这里是json&#39;);
class wechatappmsg{
  function getappmsg($content){
    //require_once &#39;db.php&#39;;
    $jsonstr=$content;
    //   $jsonstr=&#39;{"msg_item":[{"id":79544,"type":9},{}]}&#39;;
    $jsonstr = iconv(&#39;gbk&#39;, &#39;utf-8&#39;, $jsonstr);
    $result = json_decode($jsonstr);
    $name=$result->msg_item;
    // var_dump($name);
    //   echo &#39;<br/>json:&#39;.$result;
    $size=count($name);
    echo &#39;<br/>size:&#39;.$size;
    //  exit;
    for($i=0;$i<$size;$i++){
      $multi_item=$name[$i]->multi_item;
      $size2=count($multi_item);
      $app_id=$name[$i]->app_id;
      $create_time=$name[$i]->date_time;//发送时间
      //  echo &#39;<br/>app_id:&#39;.$app_id;
      $create_time=date ("Y-m-d H:i:s", $create_time);//时间转换
      echo &#39;<br/>create_time:&#39;.$create_time;
      for($j=0;$j<$size2;$j++){
        $title=$multi_item[$j]->title;//标题
        $pic_url=$multi_item[$j]->cover;//图片地址
        $digest=$multi_item[$j]->digest;//简要
        $content_url=$multi_item[$j]->content_url;//图文地址
        $t = iconv(&#39;utf-8&#39;, &#39;gbk&#39;, $title);
        echo &#39;<br/>title:&#39;.$t;
        echo &#39;<br/>Link:&#39;.$content_url;
        preg_match("/mid=([0-9]+)&/",$content_url,$string);
        $app_mid=$string[1];//一次发送的多个图文，这个ID值可以判断这两个图文是同一次发送的
        echo &#39;<br/>app_mid:&#39;.$app_mid;

//$x=saveappmsg($pic_url,$title,$digest,$content_url,$create_time,$app_mid);
 sleep(3);
      }
      echo &#39;<br/>-------------------------------------&#39;;
    }
  }
}
?>

Database:

The user replies with the keyword, and then queries and replies with the corresponding graphic information

1》Query based on the issue number:

.

select app_id from table where title like '%162期%' limit 1;
select * from table where app_id=XXXXX;

2》Based on keywords:

select * from table where title like '%故事%' limit 10;
