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(

'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, $fakeid);//获取所有用户信息，如果默认分组，则$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就是用户的fakeid，数组方式传递
