这篇文章主要介绍了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,涉及php针对微信json格式数据的解析与正则匹配相关操作技巧,需要的朋友可以参考下
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:

直接解析json即可。
<?php
$wechatObj = new wechatappmsg();
$wechatObj->getappmsg('这里是json');
class wechatappmsg{
function getappmsg($content){
//require_once 'db.php';
$jsonstr=$content;
// $jsonstr='{"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/>-------------------------------------';
}
}
}
?>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;
