WeChat development - Php batch generates QR codes with parameters, php parameters

QR codes with parameters are very useful for channel marketing and promotion. Obtain multiple QR codes with different scene values. After the user scans them, the official account can receive event push. Fortunately, WeChat has opened this interface, so let’s study it below.

For specific interface description, please refer to the WeChat public platform developer documentation (http://mp.weixin.qq.com/wiki/18/28fc21e7ed87bec960651f0ce873ef8a.html). I will directly enter the code here.

Demo picture:

Since the generation of QR codes with parameters is limited, I generate them by number, and they will be accumulated directly the next time they are generated.

In addition, there are notes in the settings to facilitate future statistics.
