Hello Guys,
chunks are ok, but I cant re create file on backend, I'm using php and I'm trying to upload an image, any tips?Hi, I Hope to Remember your question until I have some free time to post a solution that I code my own in PHP It work with test file size untill 7 GB the Whole process (chunk and merge) are handled in PHP server side.
Hi @woodchucker Can you let me know about your solution? Now i can upload file size until 250M (5M records)
Thanks.
I open a new repo to share my solution: https://github.com/woodchucker/SplitMergePHP.git
Hello,
I have reviewed your work, thank you, but a more practical solution is needed.
index.html
js.js
upload.php
Consisting of only 3 files like,
chunk-size value can be adjusted,
Working with XMLHttpRequest,
Can you suggest a workable code that can send 7GB files without additional things such as composer?
