1、xml（信息返回用扩展语言XML来传递值）
$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>";
//加载图文模版
$picTpl = "<xml>
<ToUserName><![CDATA[%s]]></ToUserName>

2、当粉丝关注你的时候，在其微信会自动回复一条欢迎的图文信息
if(trim($postObj->MsgType) == "event" and trim($postObj->Event) == "subscribe")//判断是否是新关注
{
/*$msgType = "text";
$contentStr = "您好，欢迎您关注“生活助手”";
$resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
echo $resultStr;*/
