It seems I don't have any zip extensions installed on my php 5.1 production server on linux (eg using zip_open() I get a 'function does not exist' error). I don't fancy re-compiling, can I just drop in a .co extension file and alter my php.ini?
Have a look into PclZip as i believe it has PHP 5 support all round http://www.phpconcept.net/pclzip
Brilliant! Just the job!Cheers.
