Description:
------------
When I use mime_content_type("picture.jpg") it always returns FALSE instead of "image/jpeg". At runtime I see the error "mime_content_type(): mime_magic not initialized".

I have the following in my php.ini file:

[mime_magic]
mime_magic.magicfile = "F:/PHP5/extras/magic.mime"
mime_magic.debug = On

This information shows up correctly with phpinfo().

I also notice in the phperror.log a lot of messages along the lines of:

[27-Jul-2006 11:37:13] PHP Warning:  PHP Startup: : (F:/PHP5/extras/magic.mime:274) 'L	application/x-bootable' is not a valid mimetype, entry skipped in Unknown on line 0

Reproduce code:
---------------
$content_type = mime_content_type("picture.jpg");
if (empty($content_type)) {
   echo "content_type is empty";
}

Expected result:
----------------
I expect it to return "image/jpeg" for this file.

Actual result:
--------------
It always returns FALSE.

it sounds to me like you mime magic file is invalid and 
subsequently results in an empty mime database in PHP. This 
would explain why the function always returns false. Where did 
you get the mime magic file that you are using?

It is the one included in the zip file which I downloaded from the PHP website.

I've also tried replacing it with the one I use on my other PC which runs PHP 4, but I get the same error.

I tryed downloading the zip file with windows binaries both from lates 5 and 4 series and use thoose magic.mime, they don't work

i also tryed jusing the magic file from apache, i don't get any errors in the log with this one, but the functions both mime_content_type and finfo_open dosn?t work with this either.

This extension was deprecated a while ago. Use the fileinfo extension instead: http://pecl.php.net/package/Fileinfo

(It will replace mime_magic in core in future anyway)
