Multiple file upload with progress bar using javascript php

multiple file upload with a progress bar using javascript and php enhances user experience by allowing users to select and upload several files simultaneously while visualizing the upload progress. the process typically involves an html form that enables users to choose multiple files, combined with javascript for handling the file selection and initiating the upload.

using the xmlhttprequest or the fetch api, developers can send the files to a php script asynchronously. php processes the incoming files, handling tasks like validation, storage, and error management. to provide real-time feedback, javascript updates a progress bar that reflects the upload status for each file. this involves monitoring the upload progress through event listeners that track the upload's progress, completion, or any errors.

this approach not only improves usability but also enhances performance by allowing users to upload files without refreshing the page, making it suitable for modern web applications.
