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?__biz=MjM5NzAwNzMwMQ==&mid=201393381&idx=1&sn=5351cb8d440365c24a6abb709e4e0d8c#rd","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?__biz=MjM5NzAwNzMwMQ==&mid=201393381&idx=1&sn=5351cb8d440365c24a6abb709e4e0d8c#rd","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?__biz=MjM5NzAwNzMwMQ==&mid=201376620&idx=1&sn=a9ccae0826f5aa74476dc5936cec51f2#rd","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?__biz=MjM5NzAwNzMwMQ==&mid=201376620&idx=1&sn=a9ccae0826f5aa74476dc5936cec51f2#rd","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?__biz=MjM5NzAwNzMwMQ==&mid=201376620&idx=2&sn=21a7f8715f4b2ecc2f484fd3b04ca554#rd","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?__biz=MjM5NzAwNzMwMQ==&mid=201376620&idx=3&sn=ca0a2122e1c5d8f848fd6412ea347664#rd","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〜/:<L>","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?孩子为什么会","content_url":"http://mp.weixin.qq.com/s?__biz=MjM5NzAwNzMwMQ==&mid=201345041&idx=1&sn=b2ef53dcfd93db2737240f932a0297d5#rd","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?孩子为什么会","content_url":"http://mp.weixin.qq.com/s?__biz=MjM5NzAwNzMwMQ==&mid=201345041&idx=1&sn=b2ef53dcfd93db2737240f932a0297d5#rd","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?__biz=MjM5NzAwNzMwMQ==&mid=201345041&idx=2&sn=63ae37b620566f2dc80d4b229b98a5f4#rd","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。

数据库：

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;
