This article mainly introduces the development of custom menus in PHP WeChat in detail, which has certain reference value. Interested friends can refer to it

Currently, the custom menu of WeChat service accounts includes up to 3 Each first-level menu contains up to 5 second-level menus. The first-level menu can contain up to 4 Chinese characters, and the second-level menu can contain up to 7 Chinese characters. The extra parts will be replaced by "...". Please note that after creating a custom menu, it will take 24 hours for the WeChat client to display it due to WeChat client caching. It is recommended that when testing, you can try to unfollow the public account and follow it again, and you can see the effect after creation.

Currently, the custom menu interface can implement two types of buttons, as follows:
click: After the user clicks the click type button, the WeChat server will send the message through the message interface Push the message type event structure to the developer (refer to the Message Interface Guide), and bring the key value filled in by the developer in the button. The developer can interact with the user through the customized key value;
view:
After the user clicks the view type button, the WeChat client will open the url value (i.e. web link) filled in by the developer in the button to achieve the purpose of opening the web page. It is recommended to match the web page Authorize to obtain the user's basic information interface and obtain the user's login personal information.
