you. Thank you. That would be how you enable it on windows.Did you restart your webserver afterwards?Did you search your machine to see if you have multiple php.ini files? You could have enabled it in the wrong place. Last time I checked the Windows installer liked putting a copy in the c:\windows folder and left one in the c:\program files\php5 folder.If you're running *nix you cannot enable it that way. Generally you would need to install the php-imap5 package. example: sudo apt-get install php-imap5It should restart http for you, but you you still may need to restart Apache.
