How to upload progress bar through PHP?

I have multiple input tags, each with a multiple attribute, so as to upload multiple files of different categories. How can I get the total upload progress of files, and then display the upload progress bar?

I have looked for some cases on the Internet, but the upload progress of a single file shows that what I want is to directly implement a progress bar for uploading all files. I wonder if there is a good solution?
