模拟登录微信公共平台，实现主动信息发送；
突破订阅号一天只能发送一条信息的限制。
使用编码UTF-8
代码地址：https://github.com/itziy/wechat
使用方法：
$arr = array( ‘account‘ => ‘公众平台帐号‘, ‘password‘ => ‘密码‘ );
$w = new Weixin($arr);
//$w->getAllUserInfo();//获取所有用户信息
$w->getUserInfo($groupid, $fakeid);//获取单个用户的信息，如果是默认组，则$groupid传0
$w->sendMessage(‘群发内容‘); //群发给所有用户
$w->sendMessage(‘群发内容‘,$userId); //群发给特定用户，这里的userId是fakeid
本实例仅供参考，由此引发的法律风险，本人概不负责。谢谢。

/*
调用方式简单说明：
$arr = array(
