Using PHPZipLib with PHP4?

Posti_P e-mailed me with the problem that there's an error on Line 27. This is NOT my fault, in fact, it isn't even an error in modern PHP. The method of declaring a function in a class is the method recommended by the PHP team. This method however only works with PHP5. If you are experiencing any problems, and you're not using PHP5, please look into the docs section to see how to alter phpziplib to work with PHP4, or use ZipLib 0.2.
No significant changes have been made between version 0.2 and 0.4, other then adding bzip-support and reading zipfiles, so for writing zipfiles, 0.2 will do.
