//define your token

define("TOKEN", "token");

$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)){

                

              	$postObj = simplexml_load_string($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()

	{

        $signature = $_GET["signature"];

        $timestamp = $_GET["timestamp"];

        $nonce = $_GET["nonce"];	

        		

		$token = TOKEN;

		$tmpArr = array($token, $timestamp, $nonce);

		sort($tmpArr);

		$tmpStr = implode( $tmpArr );

		$tmpStr = sha1( $tmpStr );

		

		if( $tmpStr == $signature ){

			return true;

		}else{

			return false;

		}

	}
