新用户订阅，将由之前推送一条“Hello2BizUser”文本，变化为推送一条“subscribe”的事件。
这个在php里怎么写啊，我现在有一个公众账号，可是别人关注我后，不能马上发一条消息。

<?php/**  * wechat php test  *///define your tokendefine("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)){                              	$postObj = simplexml_load_string($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;		}	}}?>

26号前给你发是一段文本就是 xml 中的 content 。。。
之后给你发的时间 event 你在读取的时候 $keyword = trim($postObj->Content); 改成
$keyword = trim($postObj->Event); 然后判断

恩恩现在可以了，谢谢楼上。
