tus.io implimentation in PHP

Hi, we would like to impliment [login to view URL] for uploads I am telling you the use case below, There are 10 pages and user visits each of them one by one, on each page there is a javascript/jquery sound recorder, after recording it uploads file to our server, currently user has to wait till the file is being uploaded ( cant move to next page ) you need to impliment [login to view URL] in such a way that user can move to next page ( requires page reload ) the upload will keep on continue in background, also there can be multiple files quied up if the users upload speed is not good enough, also when user tries to close the page and if there are files in upload queue, you should give them alert that files are in queue and if you close the browser it will not continue, also if meanwhile you can show a progress bar for files being uploaded in queue it will be great, thanks, [login to view URL] already has php implimentation, good luck,
