/**
 *	微信公众平台PHP-SDK
 *  Wechatext为非官方微信发送API
 *  注: 用户id为通过getMsg()方法获取的FakeId值
 *  主要实现如下功能:
 *  send($id,$content) 向某用户id发送微信文字信息
 *  getUserList($page,$pagesize,$groupid) 获取用户信息
 *  getGroupList($page,$pagesize) 获取群组信息
 *  sendNews($id,$msgid) 发送图文消息
 *  getNewsList($page,$pagesize) 获取图文信息列表
 *  uploadFile($filepath,$type) 上传附件,包括图片/音频/视频
 *  addPreview($title,$author,$summary,$content,$photoid,$srcurl='')   创建新的图文信息 
 *  getFileList($type,$page,$pagesize) 获取素材库文件列表
 *  sendImage($id,$fid) 发送图片消息
 *  sendAudio($id,$fid) 发送音频消息
 *  sendVideo($id,$fid) 发送视频消息
 *  getInfo($id) 根据id获取用户资料
 *  getNewMsgNum($lastid) 获取从$lastid算起新消息的数目
 *  getTopMsg() 获取最新一条消息的数据, 此方法获取的消息id可以作为检测新消息的$lastid依据
 *  getMsg($lastid,$offset=0,$perpage=50,$day=0,$today=0,$star=0) 获取最新的消息列表, 列表将返回消息id, 用户id, 消息类型, 文字消息等参数
 *  消息返回结构:  {"id":"消息id","type":"类型号(1为文字,2为图片,3为语音)","fileId":"0","hasReply":"0","fakeId":"用户uid","nickName":"昵称","dateTime":"时间戳","content":"文字内容"} 
 *  getMsgImage($msgid,$mode='large') 若消息type类型为2, 调用此方法获取图片数据
 *  getMsgVoice($msgid) 若消息type类型为3, 调用此方法获取语音数据
 *  quickSetInterface($url, $token) 快速设置接口信息
 *  getCommonInfo($dir) 获取公众账号基本信息, 其中包含：nickname,avatar,type,qrcode,appid,appsecret
