1.When uploading, when the move_uploaded_file function is not used, whether the client file has been transferred to the temporary directory (use the files array to get related information)

2. If it has been uploaded, after how long it will be automatically cleared! !!

3. When the move_uploaded_file function is used up, does the temporary file still exist!

4. Can private and var in the PHP class be used in functions in the class?

o I have not used the move_uploaded_file function, I generally use form submission directly. After submitting using the form, it does exist in the Timeline folder. You can use the code to delete at that time, or you can wait for the server to delete itself. It should be deleted when the session is effective.

In class
var-defined variables can be used outside the class
Private-defined variables can only be used in this class.

This should be right

I am asking whether these two definitions can be used in functions, such as
private function aaa ()
{}
