Is it safe to use the standard /tmp folder with upload_tmp_dir in PHP?

Question

I was wondering if there is any security risk when using the default upload_tmp_dir value in the php.ini file? If yes, what are better approaches or places to place these files?

Answer 1

/tmp means temporary. So this folder may normally be cleared regularly. You should create a /upload folder and put your files inside it.

EDIT : Excuse me I didn't anwer properly. I think there is no security risk if the folder is not accessible from the internet. For example outside the www folder.
