Firstly, the zlib library is there in under 5% of the situations.

I used a php file to unzip files, a phpzip library actually. But turns out
that on some servers, there are some difficulties that the files created are
registered to the php "user" and ftp cannot delete them. Since this is on
unix based systems, I overcame this by using
exec("tar -xvwf $filename");
And the other regular method can work as a fallback method.
