Upload zip, rar in one folder specific and Extract zip, rar in one folder specific

[Gypaete]

I had to download the "Pclzip" to extract the .Zip.

Now the problem I have is, for example, this is the contents of a zip:
mybb_1604 (Folder) -> (Inside the folder) php files.

In order to extract the contents should be:
PHP files (inside the zip)

How I can do with PHP (if so), it enters the folder "mybb_1604" to extract the files?

I hope you understand me.
