PHP – Enable FileInfo in Windows

1. Add php_fileinfo.dll to the list of enabled extensions 

extension=php_fileinfo.dll

2. Download GNU file package for windows
get it from here: http://gnuwin32.sourceforge.net/downlinks/file-bin-zip.php

Extract the folder from the archive called shared\file which contains 4 magic files (magic, magic.mgc, magic.mime, magic.mime.mgc).

3. Place these 4 files in a known place

4. Add system enviroment variable MAGIC that points to the file called magic. For example if you placed magic files in folder called magic in c:\php that means that the propper path is c:\php\magic\magic

5. If you use IIS restart it and fileinfo is ready for use

5a. If you use apache you will have to restart operating system for the service to acknowledge MAGIC env. variable.
