一、打通微信与服务器之间的通讯

编辑index.php

<?php

define(‘TOKEN‘,‘yida‘);
$obj  = new weixin();

if(!isset($_GET[‘echostr‘])) {
    
    $obj->receive();

}else{
    
    $obj->checkSignature();
}



class weixin{
    /**
     * 验证服务器与微信间的通讯
     * @return [type] [description]
     */
    public function checkSignature() {
        $signature = $_GET["signature"];
        $timestamp = $_GET["timestamp"];
        $nonce = $_GET["nonce"];    
                    
        $token = TOKEN;
        $tmpArr = array($token, $timestamp, $nonce);
        sort($tmpArr, SORT_STRING);
        $tmpStr = implode( $tmpArr );
        $tmpStr = sha1( $tmpStr );
        
        if( $tmpStr == $signature ){
            echo $_GET[‘echostr‘];
        }else{
            return false;
        }
    }

}

二、接收微信发送的消息及记录日志

/**
     * 接收微信的文本信息
     * @return [type] [description]
     */
    public function receive(){
        //微信接收的全局函数
        $obj = $GLOBALS[‘HTTP_RAW_POST_DATA‘];
        //将xml转换为对象(LIBXML_NOCDATA 是忽略SimpleXMLElement类中的CDATA)
        $xmlobj = simplexml_load_file($obj,‘SimpleXMLELement‘,LIBXML_NOCDATA);


        $this->addlog("接收：".$obj);
    }
    
    /**
     * 记录日志
     * @param  [type] $content [要记录的内容]
     */
    private function addlog($content){
        $logsize = 100000;
        $log = "log.txt";
        //判断文件是否存在及文件大小
        if(file_exists($log) && filesize($log)>$logsize){
            unlink($log);
        }
        //追加的方式写入
        file_put_contents($log,date(‘H:i:s‘)." ".$content.‘\n‘,FILE_APPEND);
    }

三、回复微信的发送信息

   /**
     * 接收微信的文本信息
     * @return [type] [description]
     */
    public function receive(){
        //微信接收的全局函数
        $obj = $GLOBALS[‘HTTP_RAW_POST_DATA‘];
        //将xml转换为对象(LIBXML_NOCDATA 是忽略SimpleXMLElement类中的CDATA)
        $xmlobj = simplexml_load_string($obj,‘SimpleXMLElement‘,LIBXML_NOCDATA);

        $this->addlog("接收：".$xmlobj);

        if(!empty($xmlobj)){
            switch (trim( $xmlobj->MsgType )){
                case ‘text‘:
                    $result = $this->receiveText($xmlobj);
                    if(!empty($result)){
                        echo $result;
                    }else{
                       $xml = "<xml>
                                <ToUserName><![CDATA[%s]]></ToUserName>
                                <FromUserName><![CDATA[%s]]></FromUserName>
                                <CreateTime>%s</CreateTime>
                                <MsgType><![CDATA[%s]]></MsgType>
                                <Content><![CDATA[%s]]></Content>
                                </xml>";
                      $result = sprintf($xml,$xmlobj->FromUserName,$xmlobj->ToUserName,time(),$xmlobj->MsgType,‘没有这条消息‘);    
                       echo $result;    
                    }
 break;
            }
        }
    }



   /**
     * 回复微信内容
     * @param  [type] $xmlobj [description]
     * @return [type]         [description]
     */
    private function receiveText($xmlobj){
        $content = trim($xmlobj->Content);
        if(strstr($content,‘你好‘)){
            $xml = "<xml>
                    <ToUserName><![CDATA[%s]]></ToUserName>
                    <FromUserName><![CDATA[%s]]></FromUserName>
                    <CreateTime>%s</CreateTime>
                    <MsgType><![CDATA[%s]]></MsgType>
                    <Content><![CDATA[%s]]></Content>
                    </xml>";
            $result = sprintf($xml,$xmlobj->FromUserName,$xmlobj->ToUserName,time(),$xmlobj->MsgType,‘hello‘);    
            return $result;    
        }
    }

四、微信回复单图文消息

   /**
     * 回复微信内容
     * @param  [type] $xmlobj [description]
     * @return [type]         [description]
     */
    private function receiveText($xmlobj){
        $content = trim($xmlobj->Content);
        if(strstr($content,‘你好‘)){
            $xml = "<xml>
                    <ToUserName><![CDATA[%s]]></ToUserName>
                    <FromUserName><![CDATA[%s]]></FromUserName>
                    <CreateTime>%s</CreateTime>
                    <MsgType><![CDATA[%s]]></MsgType>
                    <Content><![CDATA[%s]]></Content>
                    </xml>";
            $result = sprintf($xml,$xmlobj->FromUserName,$xmlobj->ToUserName,time(),$xmlobj->MsgType,‘hello‘);    
        }else if(strstr($content,‘单图文‘)){
            $result = $this->receiveImage($xmlobj);
        }
        return $result;    
    }


   /**
     * 发送单图文消息
     * @param  [type] $xmlobj [description]
     * @return [type]         [description]
     */
    private function receiveImage($xmlobj){
        $xml = "<xml>
                <ToUserName><![CDATA[%s]]></ToUserName>
                <FromUserName><![CDATA[%s]]></FromUserName>

                </item>
                </Articles>
                </xml> ";
        $result = sprintf($xml,$xmlobj->FromUserName,$xmlobj->ToUserName,time(),‘news‘,‘学习微信开发‘,‘新版《规定》明确将各类新媒体纳入管理范畴，
                  指出通过互联网站、应用程序、论坛、博客、微博客、公众账号、即时通信工具、网络直播等形式向社会公众提供互联网新闻信息服务‘,‘http://cms-bucket.nosdn.127.net/53164193c75f4fee90992cbe9c17086c20170503095700.jpeg?imageView&thumbnail=380y187&quality=85‘,‘http://www.baidu.com‘);
        return $result;
    }

五、微信回复多图文消息

  /**
     * 回复微信内容
     * @param  [type] $xmlobj [description]
     * @return [type]         [description]
     */
    private function receiveText($xmlobj){
