Novices ask for advice on how to download files in sections
For example, for a 10M file, I want to split it into 5 parts. The front end sends 5 requests to download the file at the same time, and then synthesizes it into one file. How can I achieve this using PHP (after some research, I found that the range field in the header is operated. , but I don’t understand it very well) It’s best if you can give an example, thank you guys! ! !
