Although this is not how to related to horde, I am posting this here as fileinfo is quite useful and I couldnt get it working for quite some time.

1. Read the /horde/doc/INSTALL\footnote{http://www.horde.org/horde/docs/?f=INSTALL.html}\newline
2. \texttt{pear install fileinfo-beta} will not work on RHEL without the following package.\newline
3. Get the latest file package from ftp://ftp.gw.com/mirrors/pub/unix/file/\footnote{ftp://ftp.gw.com/mirrors/pub/unix/file/}\newline
4. Install it with \texttt{./configure --prefix=/usr \&\& make \&\& make install}\newline
5. then \texttt{pear install fileinfo-beta} note: it is now changed to \texttt{pecl install fileinfo-beta}\newline
6. Add the following in \texttt{php.ini}\newline
\begin{verbatim}

;Magic mime time
mime_magic.magicfile = "/usr/share/file/magic.mime"

extension=fileinfo.so

;;;;
; Note: For Red Hat Linux, packaged extension modules are now loaded via
; the ini files in the directory /etc/php.d.
;;;;
\end{verbatim}

\newline
so also add in \texttt{/etc/php.d/fileinfo.ini}\newline
\begin{verbatim}

extension=fileinfo.so
\end{verbatim}

\newline
7. restart apache and check \texttt{/horde/test.php}. At this point I got MIME Magic Support: YesI get the following errors in \texttt{/var/log/httpd/error\_log}, not sure how to get rid of them and if it hampers the fileinfo functioning.\newline
\begin{verbatim}

\end{verbatim}

Request for anyone who has done the above in a proper way, do share and modify what needs to be done right.Jigish.gohil at gmail dot com

Note: If you're getting \textsl{\textbf{Function registration failed - duplicate name}} errors, you probably have the module registered twice as an extension.\newline
As an example, modules are loaded (on Raw: FreeBSD) from /usr/local/etc/php/extensions.ini.  If you had an entry for fileinfo.so inside extensions.ini,\newline
and then you added another "extension=fileinfo.so" in php.ini - it would try to load twice (once from extensions.ini and once from php.ini), causing \newline
the above errors.  I realize the location and names of files may be different on a Red Hat system, and I use Raw: FreeBSD - but the explanation is\newline
still valid.\newline

\noindent\rule{\textwidth}{1pt}
For Fedora Core 4, do the following:

1. \texttt{yum install php-devel}\newline
2. \texttt{pear install fileinfo}\newline
3. Add the following in \texttt{php.ini}\newline
\begin{verbatim}

;Magic mime time
mime_magic.magicfile = "/usr/share/file/magic.mime"

extension=fileinfo.so

;;;;
; Note: For Red Hat Linux, packaged extension modules are now loaded via
; the ini files in the directory /etc/php.d.
;;;;
\end{verbatim}

\newline
so also add in \texttt{/etc/php.d/fileinfo.ini}\newline
\begin{verbatim}

extension=fileinfo.so
\end{verbatim}

\newline
4. restart apache and check \texttt{/horde/test.php}. At this point I got MIME Magic Support: Yestom at kofler dot eu dot org

\textbf{NOTE: Most Unix-like systems doesn't correctly handle Microsoft Word and Microsoft Excel MIME types. If you very heavy rely on these types, use integrated Horde MIME magic library instead. See bug \#3565\footnote{http://bugs.horde.org/ticket/?id=3565} for more info.}
