Php development-generate two-dimensional codes with parameters in batches. php batch Parameters

The two-dimensional code with parameters is very useful for channel marketing and promotion. Multiple two-dimensional codes with different scenario values can be obtained. After a user scans the QR code, the public number can receive event push, the good news is that we have activated this interface. Let's take a look at it.
For details about the interface, see the public platform developer documentation (http://mp.weixin.qq.com/wiki/18/28fc21e7ed87bec960651f0ce873ef8a.html), I am here on the Code directly.

Due to the limited generation of QR codes with parameters, all codes are generated by serial numbers and will be accumulated at the next generation.
In addition, remarks are provided to facilitate future statistics.

It's easy. It's basically enough. Just take it if you like it.
