The data file for my new script, CBIntuition, comes from the ClickBank Marketplace in ZIP format. I've been tearing my hair out trying to get a PHP script to unzip it.
Most of the scripts that I've found depend upon the Zlib library being linked in to PHP on the host server. My host's servers don't appear to have the library built in, and as I don't own the host servers, I can't add it.
A new friend of mine, found via an online forum, has just furnished me with a library, DUnzip2 that will do the job. It's not his library, but I have to say thanks to him the Admin of CBIntuition is now one step nearer completion.
