微信开发之Php批量生成带参数的二维码

带 参数 的二维码对于渠道营销推广来说是很有用的，可以获得多个带不同场景值的二维码，用户扫描后，公众号可以接收到事件推送，可喜的是微信开通了这个接口，那下面就来研究一下吧。 具体接口说明请参见，微信公众平台 开发 者文档（http://mp.weixin.qq.co

带参数的二维码对于渠道营销推广来说是很有用的，可以获得多个带不同场景值的二维码，用户扫描后，公众号可以接收到事件推送，可喜的是微信开通了这个接口，那下面就来研究一下吧。

具体接口说明请参见，微信公众平台开发者文档（http://mp.weixin.qq.com/wiki/18/28fc21e7ed87bec960651f0ce873ef8a.html），我这里就直接上代码。

演示图：

由于带参数二维码生成是有限的，所有我是按编号生成的，下次生成的时候直接累加。

另外带设置有备注，方便以后统计。
