PHPs mime_content_type() fail on windows.

Question

I know mime_content_type() is deprecated, but it seemed to me the alternative is worse at the moment. Finfo seems to require adding files and changing ini directions on windows; I don't want to require this for the script I am making.

I need to find the mimetype of files, but when calling mime_content_type($filename) on windows it fails. mime_magic.magicfile points to the correct file, but when enabling mime_magic.debug in the ini file, I get this error message:

Warning: mime_content_type()[http://www.php.net/mime_magic]: mime_magic not initialized in C:\xampp\htdocs\test.php on line 2

I am not sure if that is a problem or if it still happens when I disable the debugging and it just doesn't tell me.

I checked, and extension=php_mime_magic.dll is enabled in the ini file and httpd.conf specifies

LoadModule mime_module modules/mod_mime.so
#LoadModule mime_magic_module modules/mod_mime_magic.so

I am using XAMPP 1.6.5.

This may be related to this bug report. Do you have any errors in your error log when you call the script along the lines of 'FOO' is not a valid mimetype, entry skipped?

Unfortunately the final response in that particular thread was to go ahead and use Fileinfo..

Reading through another thread describing the same problem - when you turned on debug, did you set it to "On" or 1? Shouldn't make a difference, but in the thread linked above that seems like part of the solution in that case.

What are you getting when you echo out the value of mime_content_type with debugging turned off?

Have you tried finfo_buffer? That allows you to use the file as a string, so you could do:

$finfo = new finfo;
$filename = $_GET['filename'];
var_dump($finfo->buffer(file_get_contents($filename)));

Also an issue from that bug report was that the mime database was out of date - have you tried with a different copy?

Fileinfo can be a trick to get going on Windows. Instructions here: http://forums.zend.com/viewtopic.php?f=8&t=337#p14681
