The correct little correction:
exec will return the mime with a newline at the end, the trim() should be called with the result of exec, not the other way around.
<?php
if ( ! function_exists ( 'mime_content_type ' ) )
{
function mime_content_type ( $f )
{
return trim ( exec ('file -bi ' . escapeshellarg ( $f ) ) ) ;
}
}
?>
mime_content_type
Description
string mime_content_type ( string filename )Returns the MIME content type for a file as determined by using information from the magic.mime file. Content types are returned in MIME format, like text/plain or application/octet-stream.

if you use a transparent 'spacer' GIF i've found it needs to be a around 25x25 for it to register as 'image/gif'. otherwise it's read in as 'text/plain'.

Completing <some dude AT somewhere DOT com> comment:
0 string < ? php application/x-httpd-php
and string detection on text files may fail if you check a file encoded with signed UTF-8. The UTF-8 signature is a two bytes code (0xFF 0xFE) that prepends the file in order to force UTF-8 recognition (you may check it on an hexadecimal editor).

The 'file' utility fortunately is available for Windows, too:

I added these two lines to my magic.mime file:
0 string \<?php application/x-httpd-php
0 string <?xml text/xml
The first one may not work if "<?php" is not at the very beginning of your file, e.g., if some HTML preceeds the first bit of PHP code. The second one should work because "<?xml" *should* be the first thing in every XML file.

The function mime_content_type only worked for me on Microsoft Windows after I added the directive "mime_magic.debug" to my php.ini with the value of "On". The default value appears to be "Off". Exampe:
[mime_magic]
mime_magic.debug = On
mime_magic.magicfile = "c:\php\extras\magic.mime"

This works on windows too. Make sure to uncomment the following in your php.ini file:
extension=php_mime_magic.dll
Also make sure to add the following line anywhere inside the php.ini file:
mime_magic.magicfile = "C:\path\to\php\install\magic.mime"
Voila working mime content types in windows :)

Note that you will need /bin/sh as well as the file(1) program for this function to work. This is relevant when setting apache up in a chroot-environment. Took me a while to find that out.
