gives you an idea. Many people like to use recursion to solve problems, but if it is a folder, this is ridiculous. If I have 20 layers of files, do you want to use scandir to get them recursively? It certainly won't work like this. A good solution is to click on the directory and get the structure in the directory. In this way, the pressure will not be great. In this way, it is relatively easy for you to write the interface, you only need to get one layer. There are parent_id and children. Of course, it's not impossible for you to use recursion to get everything. Let the user wait a little longer. If there are too many files, wait until the end of time
