I\'m in the process of using PHPExcel. One of the requirements is that I need to enable php_zip.
(...) if you need PHPExcel to handle .xlsx or .ods files
I've had a similar problem with a different library. WAMP doesn't include many libraries by default for some reason.
What I did was download the full PHP installation as a zip from php.net and the required dll was found in the extensions folder just as it is in WAMP. I just copied it from the zip to the WAMP extension folder and it worked fine.
In fact, Zip is included by default. It is a bug that the line is still included.
marc answer is right. I wanted to add a comment that using
extension_loaded('zip');
returns false as it is no longer an extension, you could use
class_exists('ZipArchive');
to check for it now.
