}这部分代码就是用于自动回复的,你需要把你的逻辑写在里面,比如用户发过来的内容中包含什么关键字,你就回复什么内容。
$keyword就是用户说的话,$contentStr就是你要给用户回复的内容。它需要使用sprintf包装成xml结构,然后发回给微信服务器,微信服务器再发送给用户。
$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
$fromUsername = $postObj->FromUserName;
$toUsername = $postObj->ToUserName;
$keyword = trim($postObj->Content);
$time = time();
再看这一段,$fromUsername应该就是发消息过来的用户名。这个应该就是你的用户名。$keyword就是用户说的话,根据这些信息,写你自己的逻辑就行了,
