本篇文章主要讲述的是PHP实现微信公众号图文消息回复与access_token，具有一定的参考价值，感兴趣的朋友可以了解一下。
//代码如下
<?php
class IndexAction extends Action {
public function __construct(){
}
public function index(){
//获得参数 signature nonce token timestamp echostr
$nonce = $_GET['nonce'];
$token = 'imooc';
$timestamp = $_GET['timestamp'];
$echostr = $_GET['echostr'];
$signature = $_GET['signature'];
//形成数组，然后按字典序排序
$array = array();
$array = array($nonce, $timestamp, $token);
sort($array);
//拼接成字符串,sha1加密 ，然后与signature进行校验
$str = sha1( implode( $array ) );
if( $str == $signature && $echostr ){
//第一次接入weixin api接口的时候
echo $echostr;
exit;
}else{
$this->reponseMsg();
}
}
// 接收事件推送并回复
public function reponseMsg(){
//1.获取到微信推送过来post数据（xml格式）
$postArr = $GLOBALS['HTTP_RAW_POST_DATA'];
//2.处理消息类型，并设置回复类型和内容
