/**
Name: PHP MimeType Class
Version: 1.0
Date Released: 10/20/02
Description: This class allows a PHP script to determine the mime type
a file based on the file extension. This class is handy for PHP versions
without the benefit of other tools to determine the mime type. The class
defaults to octet-stream so if the file type is not recognized the user
is presented with a file download prompt.
NOTES: The mime types for this version are based on Apache 1.3.27
mime types may change or need to be added in the future, the mime types
are stored in an array so that an awk or other script can automatically
generate the code to make the array.
Usage:
First an instance of the mimetype class must be created, then the
getType method should be called with the filename. It will return
the mime type, an example follows.
Example:
$mimetype = new mimetype();
print $mimetype->getType('acrobat.pdf');
