本文实例为大家分享了php微信文本消息自动回复 别代码，供大家参考，具体内容如下

1.PHP示例代码下载  下载地址1：http://xiazai.jb51.net/201608/yuanma/phpwx(jb51.net).rar  下载地址2：https://mp.weixin.qq.com/wiki/home/index.html（开始开发-》接入指南-》PHP示例代码下载） 

2.wx_sample.php初始代码 


<?php
/**
 * wechat php test
 */

//define your token
define("TOKEN", "weixin");
$wechatObj = new wechatCallbackapiTest();
$wechatObj->valid();

class wechatCallbackapiTest
{
 public function valid()
 {
 $echoStr = $_GET["echostr"];

 //valid signature , option
 if($this->checkSignature()){
 echo $echoStr;
 exit;
 }
 }

 public function responseMsg()
 {
 //get post data, May be due to the different environments
 $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];

 //extract post data
 if (!empty($postStr)){
 /* libxml_disable_entity_loader is to prevent XML eXternal Entity Injection,
 the best way is to check the validity of xml by yourself */
 libxml_disable_entity_loader(true);
 $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
 $fromUsername = $postObj->FromUserName;
 $toUsername = $postObj->ToUserName;
 $keyword = trim($postObj->Content);
 $time = time();
 $textTpl = "<xml>
 <ToUserName><![CDATA[%s]]></ToUserName>
 <FromUserName><![CDATA[%s]]></FromUserName>
 <CreateTime>%s</CreateTime>
 <MsgType><![CDATA[%s]]></MsgType>
 <Content><![CDATA[%s]]></Content>
 <FuncFlag>0</FuncFlag>
 </xml>"; 
 if(!empty( $keyword ))
 {
 $msgType = "text";
 $contentStr = "Welcome to wechat world!";
 $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
 echo $resultStr;
 }else{
 echo "Input something...";
 }

 }else {
 echo "";
 exit;
 }
 }
 
 private function checkSignature()
 {
 // you must define TOKEN by yourself
 if (!defined("TOKEN")) {
 throw new Exception('TOKEN is not defined!');
 }
 
 $signature = $_GET["signature"];
 $timestamp = $_GET["timestamp"];
 $nonce = $_GET["nonce"];
 
 $token = TOKEN;
 $tmpArr = array($token, $timestamp, $nonce);
 // use SORT_STRING rule
 sort($tmpArr, SORT_STRING);
 $tmpStr = implode( $tmpArr );
 $tmpStr = sha1( $tmpStr );
 
 if( $tmpStr == $signature ){
 return true;
 }else{
 return false;
 }
 }
}

?>

3.调用回复信息方法  在wx_sample.php文件中注释掉$wechatObj->valid();，在其下增加一句“$wechatObj->responseMsg();”。 


<?php
/**
 * wechat php test
 */

//define your token
define("TOKEN", "weixin");
$wechatObj = new wechatCallbackapiTest();
//$wechatObj->valid();//接口验证
$wechatObj->responseMsg();//调用回复消息方法
class wechatCallbackapiTest
{
 public function valid()
 {
 $echoStr = $_GET["echostr"];

 //valid signature , option
 if($this->checkSignature()){
 echo $echoStr;
 exit;
 }
 }

 public function responseMsg()
 {
 //get post data, May be due to the different environments
 $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];

 //extract post data
 if (!empty($postStr)){
 /* libxml_disable_entity_loader is to prevent XML eXternal Entity Injection,
 the best way is to check the validity of xml by yourself */
 libxml_disable_entity_loader(true);
 $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
 $fromUsername = $postObj->FromUserName;
 $toUsername = $postObj->ToUserName;
 $keyword = trim($postObj->Content);
 $time = time();
 $textTpl = "<xml>
 <ToUserName><![CDATA[%s]]></ToUserName>
 <FromUserName><![CDATA[%s]]></FromUserName>
 <CreateTime>%s</CreateTime>
 <MsgType><![CDATA[%s]]></MsgType>
 <Content><![CDATA[%s]]></Content>
 <FuncFlag>0</FuncFlag>
 </xml>"; 
 if(!empty( $keyword ))
 {
 $msgType = "text";
 $contentStr = "Welcome to wechat world!";
 $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
 echo $resultStr;
 }else{
 echo "Input something...";
 }

 }else {
 echo "";
 exit;
 }
 }
 
 private function checkSignature()
 {
 // you must define TOKEN by yourself
 if (!defined("TOKEN")) {
 throw new Exception('TOKEN is not defined!');
 }
 
 $signature = $_GET["signature"];
 $timestamp = $_GET["timestamp"];
 $nonce = $_GET["nonce"];
 
 $token = TOKEN;
 $tmpArr = array($token, $timestamp, $nonce);
 // use SORT_STRING rule
 sort($tmpArr, SORT_STRING);
 $tmpStr = implode( $tmpArr );
 $tmpStr = sha1( $tmpStr );
 
 if( $tmpStr == $signature ){
 return true;
 }else{
 return false;
 }
 }
}

?>

4.关键词自动回复和关注回复  $keyword保存着用户微信端发来的文本信息。  官方开发者文档：https://mp.weixin.qq.com/wiki/home/index.html（消息管理-》接收消息-接收事件推送-》1.关注/取消关注事件）

关注事件与一般的文本消息有两处不同，一是MsgType值是event，二是增加了Event值是subscribe。由于官方文档（最初的wx_sample.php）没有提取这个参数，需要我们自己提取。在程序中增加两个变量$msgType和$event。 


<?php
/**
 * wechat php test
 */

//define your token
define("TOKEN", "weixin");
$wechatObj = new wechatCallbackapiTest();
//$wechatObj->valid();//接口验证
$wechatObj->responseMsg();//调用回复消息方法
class wechatCallbackapiTest
{
 public function valid()
 {
 $echoStr = $_GET["echostr"];

 //valid signature , option
 if($this->checkSignature()){
 echo $echoStr;
 exit;
 }
 }

 public function responseMsg()
 {
 //get post data, May be due to the different environments
 $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];

 //extract post data
 if (!empty($postStr)){
 /* libxml_disable_entity_loader is to prevent XML eXternal Entity Injection,
 the best way is to check the validity of xml by yourself */
 libxml_disable_entity_loader(true);
 $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
 $fromUsername = $postObj->FromUserName;
 $toUsername = $postObj->ToUserName;
 $keyword = trim($postObj->Content);
 $time = time();
 $msgType = $postObj->MsgType;//消息类型
 $event = $postObj->Event;//时间类型，subscribe（订阅）、unsubscribe（取消订阅）
 $textTpl = "<xml>
 <ToUserName><![CDATA[%s]]></ToUserName>
 <FromUserName><![CDATA[%s]]></FromUserName>
 <CreateTime>%s</CreateTime>
 <MsgType><![CDATA[%s]]></MsgType>
 <Content><![CDATA[%s]]></Content>
 <FuncFlag>0</FuncFlag>
 </xml>"; 
 
 switch($msgType){
 case "event":
 if($event=="subscribe"){
 $contentStr = "Hi,欢迎关注海仙日用百货!"."\n"."回复数字'1',了解店铺地址."."\n"."回复数字'2',了解商品种类.";
 } 
 break;
 case "text":
 switch($keyword){
 case "1":
 $contentStr = "店铺地址："."\n"."杭州市江干艮山西路233号新东升市场地下室第一排."; 
 break;
 case "2":
 $contentStr = "商品种类:"."\n"."杯子、碗、棉签、水桶、垃圾桶、洗碗巾(刷)、拖把、扫把、"
 ."衣架、粘钩、牙签、垃圾袋、保鲜袋(膜)、剪刀、水果刀、饭盒等.";
 break;
 default:
 $contentStr = "对不起,你的内容我会稍后回复";
 }
 break;
 }
 $msgType = "text";
 $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
 echo $resultStr;
 }else {
 echo "";
 exit;
 }
 }
 
 private function checkSignature()
 {
 // you must define TOKEN by yourself
 if (!defined("TOKEN")) {
 throw new Exception('TOKEN is not defined!');
 }
 
 $signature = $_GET["signature"];
 $timestamp = $_GET["timestamp"];
 $nonce = $_GET["nonce"];
 
 $token = TOKEN;
 $tmpArr = array($token, $timestamp, $nonce);
 // use SORT_STRING rule
 sort($tmpArr, SORT_STRING);
 $tmpStr = implode( $tmpArr );
 $tmpStr = sha1( $tmpStr );
 
 if( $tmpStr == $signature ){
 return true;
 }else{
 return false;
 }
 }
}


?>
