Question

Can i also use file_put_contents($fileapp,$content,FILE_BINARY); to move uploaded files?

Answer 1

You can. But why not use move_uploaded_file() instead? This is generally considered to be safer than trying to access the path in $_FILES, since move_uploaded_file() does check if the file really is a file and if it was actually uploaded by the user.

If you can’t use the move_uploaded_file(), remember to call is_uploaded_file() before you do the file_put_contents() call. Just for your own safety.
