In the PHP 5.3.13 CLI version, it might use the "MAGIC" environnement variable to get the magic database file. Due to the fact that this version doesn't use the standard format, this file may be wrong. You can see it via a simple script : 

<?php
    var_dump($_SERVER['MAGIC']);
?>

Unset this variable and it will work again. You can use unsetenv (C-Shell) or unset (Bourne Shell).

This does not affect the Apache version. Other CLI versions might be affected.

I lost a lot of time on this undocumented issue.

In addition to
 extension=fileinfo.so
I also had to add
 mime_magic.magicfile=/usr/share/file/magic
to my php configuration.  Then, I instantiate Finfo thus:

<?php
$mimeMagicFile = get_cfg_var('mime_magic.magicfile');
$finfo = new finfo(FILEINFO_MIME, $mimeMagicFile);
?>

(This is despite the rumours I hear about the default being exactly what I set it to anyway.)

On Ubuntu Feisty, you need to add the line

extension=fileinfo.so

to your /etc/php5/*/php.ini files. The extension gets linked at compile time to /usr/lib/libmagic.so.1 which uses a MAGIC environment variable which defaults to 

/etc/magic:/usr/share/file/magic
