The example in this article describes how to upload files in php and display the upload progress. Share it with everyone for your reference. The details are as follows:
Remember to make the file larger when uploading, otherwise it will be uploaded before you can see it, and the uploaded file should not be too big. Forget about G. I tried 2G, but PHP couldn't stand it. The one I tested was 300 There are so many M, remember to adjust the small php.ini parameters "Select file => Submit => Get information" in one go ^ ^
