本文实例讲述了PHP使用微信开发模式实现搜索已发送图文及匹配关键字回复的方法。分享给大家供大家参考，具体如下：

用户发送关键字，搜索相应的图文进行回复。

模拟登陆就不说了

右键看“已发送”图片页的源代码，图文部分是json格式的。
复制代码 代码如下:{"msg_item":[{"id":80630,"type":9,"fakeid":"2397007301","nick_name":"每天学点心理学","date_time":1403445168,"content":"","source":"mass","msg_status":2,"title":"（第167期）| 我读过的具有正能量的一篇文章，为你取暖","desc":"传说世间的一切生灵皆可修炼成仙，而猫自然在其中。每修炼二十年，猫就会多长出一条尾巴，等到有...","content_url":"http:\/\/mp.weixin.qq.com\/s","show_type":1,"file_id":201393328,"app_sub_type":3,"comment_url":"","has_reply":0,"refuse_reason":"","multi_item":[{"seq":0,"cover":"https:\/\/mmbiz.qlogo.cn\/mmbiz\/jOtiajqZ1n62uicM0XBZkqUB5BdJRdCMt0Y3CDIApNglh6Lj5zcmfm0mqN0YyGkNvekxP7j0uqs95AQejwZpTfCg\/0","title":"（第167期）| 我读过的具有正能量的一篇文章，为你取暖","digest":"传说世间的一切生灵皆可修炼成仙，而猫自然在其中。每修炼二十年，猫就会多长出一条尾巴，等到有...","content_url":"http:\/\/mp.weixin.qq.com\/s","file_id":201393328,"content":"","source_url":"","author":"","show_cover_pic":0,"vote_id":[]}],"to_uin":0,"send_stat":{"total":1656,"succ":1656,"fail":0}},{"id":80444,"type":2,"fakeid":"2397007301","nick_name":"每天学点心理学","date_time":1403358199,"source":"mass","msg_status":2,"comment_url":"","has_reply":0,"refuse_reason":"","multi_item":[],"to_uin":0,"send_stat":{"total":1631,"succ":1631,"fail":0}},{"id":80222,"type":9,"fakeid":"2397007301","nick_name":"每天学点心理学","date_time":1403272191,"content":"","source":"mass","msg_status":2,"title":"（第166期）| 想要的超能力，来玩一个投票娱乐下吧~","desc":"虽然没啥了不起的，但还是想要的这种超能力…-----------END-----------可以点击右上角『","content_url":"http:\/\/mp.weixin.qq.com\/s","show_type":1,"file_id":201370866,"app_sub_type":3,"comment_url":"","has_reply":0,"refuse_reason":"","multi_item":[{"seq":0,"cover":"https:\/\/mmbiz.qlogo.cn\/mmbiz\/jOtiajqZ1n62MibMmurxXEVsDbwZglIq1wSxian2K6cH8Du0l3fMgQ2GdmbovicAXpSmjslI9iaCXicCTJC5Mef8ggBA\/0","title":"（第166期）| 想要的超能力，来玩一个投票娱乐下吧~","digest":"虽然没啥了不起的，但还是想要的这种超能力…-----------END-----------可以点击右上角『","content_url":"http:\/\/mp.weixin.qq.com\/s","file_id":201370866,"content":"","source_url":"","author":"","show_cover_pic":0,"vote_id":[45050]},{"seq":1,"cover":"https:\/\/mmbiz.qlogo.cn\/mmbiz\/jOtiajqZ1n62MibMmurxXEVsDbwZglIq1w4hNsMaia4p6SXGIUU6NBwbyEbpFL2mESOJ0yuP5pJhzavHzgnyPMM1A\/0","title":"【美文】| 挥之不去的无奈","digest":"躺在床上，过往的一幕幕在脑海掠过。四年的坚持，抑或说是7年的梦想，当它破灭时，仅仅淡然一笑，谈何容易？其实行","content_url":"http:\/\/mp.weixin.qq.com\/s","file_id":201371031,"content":"","source_url":"","author":"","show_cover_pic":1,"vote_id":[]},{"seq":2,"cover":"https:\/\/mmbiz.qlogo.cn\/mmbiz\/jOtiajqZ1n62MibMmurxXEVsDbwZglIq1wNzqasiaEPYAGXQQdLnkaiaW56ueicHelZFJCjWUA3dg6ibWw15N1KQtEeQ\/0","title":"【插画】| 不是所有的伤口都能自我愈合","digest":"愿每一个相信爱的女生，都能成为爱里打不倒的战士。没有人比你更美好，因为这个世界上不会再有第二个你了。少一点依","content_url":"http:\/\/mp.weixin.qq.com\/s","file_id":201374122,"content":"","source_url":"","author":"","show_cover_pic":0,"vote_id":[]}],"to_uin":0,"send_stat":{"total":1610,"succ":1610,"fail":0}},{"id":79872,"type":1,"fakeid":"2397007301","nick_name":"每天学点心理学","date_time":1403185708,"content":"朋友们，今天休息，不发咯，你们也早点休息哟","source":"mass","msg_status":2,"comment_url":"","has_reply":0,"refuse_reason":"","multi_item":[],"to_uin":0,"send_stat":{"total":1584,"succ":1584,"fail":0}},{"id":79544,"type":9,"fakeid":"2397007301","nick_name":"每天学点心理学","date_time":1403098674,"content":"","source":"mass","msg_status":2,"title":"（第165期）| 孩子为什么会偷东西","desc":"小孩偷东西是一种很严重的行为，但好像是很多孩子在成长过程中都有偷东西一个阶段，父母该如何教育呢","content_url":"http:\/\/mp.weixin.qq.com\/s","show_type":1,"file_id":201240144,"app_sub_type":3,"comment_url":"","has_reply":0,"refuse_reason":"","multi_item":[{"seq":0,"cover":"https:\/\/mmbiz.qlogo.cn\/mmbiz\/jOtiajqZ1n60ZFQ7comgKCEXlkibVZXmJf1PqAs4czgl0AiakwonBibD5DT2ytE6tA8VJdBVibuS92XgWXbuMibKmicRg\/0","title":"（第165期）| 孩子为什么会偷东西","digest":"小孩偷东西是一种很严重的行为，但好像是很多孩子在成长过程中都有偷东西一个阶段，父母该如何教育呢","content_url":"http:\/\/mp.weixin.qq.com\/s","file_id":201240144,"content":"","source_url":"","author":"虫子","show_cover_pic":1,"vote_id":[]},{"seq":1,"cover":"https:\/\/mmbiz.qlogo.cn\/mmbiz\/jOtiajqZ1n60ZFQ7comgKCEXlkibVZXmJfRPJl3P72Vh8l46B1m6EvZY4IWRnFB0AHkxrTSbghME9TxmFyibbxXdQ\/0","title":"八张图让你明白很多","digest":"小图片，大道理。-----------END-----------可以点击右上角『分享至朋友圈』。微信号：m","content_url":"http:\/\/mp.weixin.qq.com\/s","file_id":201240187,"content":"","source_url":"","author":"虫子","show_cover_pic":0,"vote_id":[]}],"to_uin":0,"send_stat":{"total":1568,"succ":1568,"fail":0}}]}
直接解析json即可。

<"msg_item":[{"id":79544,"type":9},{}]}';
    $jsonstr = iconv('gbk', 'utf-8', $jsonstr);
    $result = json_decode($jsonstr);
    $name=$result->msg_item;
    // var_dump($name);
    //   echo '<br/>json:'.$result;
    $size=count($name);
    echo '<br/>size:'.$size;
    //  exit;
    for($i=0;$i<$size;$i++){
      $multi_item=$name[$i]->multi_item;
      $size2=count($multi_item);
      $app_id=$name[$i]->app_id;
      $create_time=$name[$i]->date_time;//发送时间
      //  echo '<br/>app_id:'.$app_id;
      $create_time=date ("Y-m-d H:i:s", $create_time);//时间转换
      echo '<br/>create_time:'.$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('utf-8', 'gbk', $title);
        echo '<br/>title:'.$t;
        echo '<br/>Link:'.$content_url;
        preg_match("/mid=([0-9]+)&/",$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 '<br/>app_mid:'.$app_mid;
        //这里可以直接进行入库
//$x=saveappmsg($pic_url,$title,$digest,$content_url,$create_time,$app_mid);
 sleep(3);
      }
      echo '<br/>-------------------------------------';
    }
  }
}

用户回复关键字，然后查询回复相应图文信息。
1》根据期数进行查询：


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




2》根据关键字：


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