通过$ _FILES或php：//输入上传文件？ 哪个系统更好？

Question

I am creating a script that via my iOS application I can upload a file. I was wondering which method is better or safer for the system? $_FILES or php://input? Does it matter? I am curious to know because users will need to upload multiple files at once, for example one user may upload one photo but 10k are doing it at once. I am just trying to prepare for a situation like that.

Any suggestions on this? I know $_FILES writes to the temp directory, I believe php://input does not though (does it use system memory)? Please help me understand. I found a few other threads on this but nothing specifically said how it affects the system & which one is better for my situation.

The files will not be bigger than 2MB at most.

Regardless of whichever you choose, php will always have the entire file in memory due to the way php handles file uploads.

I'd stick with $_FILES, it's already there to help you with the handling of file uploads with PHP.
