I have an application that uses the php fileinfo extension. The fileinfo extension is built-into PHP since 5.3.

My phpinfo.php shows that the extension is disabled.
'--disable-fileinfo'

Here is a link to my phpinfo.php
http://jeffschwartz.net/phpinfo.php

Here is a link to the extension on the PHP website:
http://us2.php.net/manual/en/fileinfo.installation.php

How do I enable the extension?

Sincerely,
Jeff Schwartz
