Files compressed using this function on Linux won't be decompressed using Windows.

There seems to be some incompatibility with Windows built-in decompressor.

There's an alternative library that works better here: https://github.com/Ne-Lexa/php-zip

I got windows to open a file created with it by using the PKWARE encryption method
