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:

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：
|
1
2
|
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：
|
1
|
select * from table where title like '%故事%' limit 10;
|
