Скрипт php для загрузки больших файлов до 4Gb

A PHP script for uploading large files (up to 4 GB) to a server. The script uploads files to an "upload" folder and is ready for immediate installation on any website; simply upload the script files to your hosting environment to get started. It is compatible with PHP 7.3 and higher. The script supports all file types but requires a modern browser; it does not work in outdated browsers like IE7. It functions by splitting the file into smaller chunks and uploading them sequentially via jQuery, thereby avoiding excessive load on the web server and PHP.
