解压zip遇到问题

ayalastrike

$zippath=realpath("test.zip";
$zip = zip_open($zippath);

时提示Fatal error: Call to undefined function: zip_open() in C:\Program Files\Apache Group\Apache2\htdocs\test\unzip.php on line 4

可是我的php.ini里已经把
extension=php_zip.dll前的;去掉了
并且在php/dll和php/extensions下都有php_zip.dll,是什么原因?

geel

extension_dir 设置了吗？
