How to upload large files above 500MB in PHP [duplicate]

Question

I made an upload page in PHP, but I dont know why the page would not upload documents greater than 500MB, This is my first time of trying to upload something that large, I changed all the configurations in the PHP.INI (post_max_size = 700M, upload_max_filesize = 600M, and max_execution_time = 300). The codes for upload is as below

if(isset($_FILES['upload']) && !empty($_FILES['upload']['name'])){  move_uploaded_file($_FILES['upload']['tmp_name'], $this->filePath.$this->fileName); } 

I need help, I wonder if there is something am not doing right..

Answer 1

Do you think if increasing upload size limit will solve the problem? what if uploading 2GB file, what's happening then? Do you take into consideration the memory usage of such a script?

Instead, what you need is chunked upload, see here : Handling plupload's chunked uploads on the server-side and here : File uploads; How to utilize "chunking"?
