a) are you sure you even need the php_zip extension? it's only required by PHPExcel in some cases.
b) what sort of problem are you having with PHPExcel? it might not have anything to do with the zip extension.
c) have you checked if the php.ini that you are changing is the one the php is using? the Loaded Configuration File output from a phpinfo() statement is the php.ini that php is using.
d) is the zip extension currently being loaded? there wound be a section present for it in the output from a phpinfo() statement.
e) have you checked your web server's error log for any relevant php_zip.dll errors, that was mentioned as something to do in the replies above in this thread?
f) have you done or checked the other things mentioned in the replies above in this thread?
