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<?phpclass 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 = $GLOBALS['HTTP_RAW_POST_DATA'];//2.处理消息类型，并设置回复类型和内容/*<xml><ToUserName><![CDATA[toUser]]></ToUserName><FromUserName><![CDATA[FromUser]]></FromUserName><CreateTime>123456789</CreateTime><MsgType><![CDATA[event]]></MsgType><Event><![CDATA[subscribe]]></Event></xml>*/$postObj = simplexml_load_string( $postArr );//$postObj->ToUserName = '';//$postObj->FromUserName = '';//$postObj->CreateTime = '';//$postObj->MsgType = '';//$postObj->Event = '';// gh_e79a177814ed//判断该数据包是否是订阅的事件推送if( strtolower( $postObj->MsgType) == 'event'){//如果是关注 subscribe 事件if( strtolower($postObj->Event == 'subscribe') ){//回复用户消息(纯文本格式)	$toUser   = $postObj->FromUserName;$fromUser = $postObj->ToUserName;$time     = time();$msgType  =  'text';$content  = '欢迎关注我们的微信公众账号'.$postObj->FromUserName.'-'.$postObj->ToUserName;$template = "<xml><ToUserName><![CDATA[%s]]></ToUserName><FromUserName><![CDATA[%s]]></FromUserName><CreateTime>%s</CreateTime><MsgType><![CDATA[%s]]></MsgType><Content><![CDATA[%s]]></Content></xml>";$info     = sprintf($template, $toUser, $fromUser, $time, $msgType, $content);echo $info;/*<xml><ToUserName><![CDATA[toUser]]></ToUserName><FromUserName><![CDATA[fromUser]]></FromUserName><CreateTime>12345678</CreateTime><MsgType><![CDATA[text]]></MsgType><Content><![CDATA[你好]]></Content></xml>*/}}//当微信用户发送imooc，公众账号回复‘imooc is very good'/*<xml><ToUserName><![CDATA[toUser]]></ToUserName><FromUserName><![CDATA[fromUser]]></FromUserName><CreateTime>12345678</CreateTime><MsgType><![CDATA[text]]></MsgType><Content><![CDATA[你好]]></Content></xml>*//*if(strtolower($postObj->MsgType) == 'text'){switch( trim($postObj->Content) ){case 1:$content = '您输入的数字是1';break;case 2:$content = '您输入的数字是2';break;case 3:$content = '您输入的数字是3';break;case 4:$content = "<a href='http://www.imooc.com'>慕课</a>";break;case '英文':$content = 'imooc is ok';break;}	$template = "<xml><ToUserName><![CDATA[%s]]></ToUserName><FromUserName><![CDATA[%s]]></FromUserName><CreateTime>%s</CreateTime><MsgType><![CDATA[%s]]></MsgType><Content><![CDATA[%s]]></Content></xml>";//注意模板中的中括号 不能少 也不能多$fromUser = $postObj->ToUserName;$toUser   = $postObj->FromUserName;
