PHP: mime_content_type() ?

I'm trying to use mime_content_type() but I get a fatal error,
Call to undefined function: mime_content_type()

My server is running PHP5 as a CGI, and I tried it w/o CGI and it still didn't work. So how can I enable this function? I would like to be able to read the file type of files uploaded through a form (ie $_FILES["file"]["tmp_name"]) , and they have random names like 3vna37 with no file extension. (BTW, I would rather not just check the file type against the ["name"] field, as people can fake a file extension and mess things up. So any help is appreciated. Thanks!

The function requires the (deprecated) Mime Magic extension to be activated. There may be an alternative you can use, but I don't know anything about it.

Thanks! I will look into that.

Hmm... this fileinfo alternative requires compiling a library into the php installation, which is out of my abilities. Thanks though.
