  49     Name: PHP MimeType Class
  50  
  51     Version: 1.0
  52     Date Released: 10/20/02
  53  
  54     Description: This class allows a PHP script to determine the mime type
  55     a file based on the file extension.  This class is handy for PHP versions
  56     without the benefit of other tools to determine the mime type.  The class
  57     defaults to octet-stream so if the file type is not recognized the user
  58     is presented with a file download prompt.
  59  
  60     NOTES: The mime types for this version are based on Apache 1.3.27
  61     mime types may change or need to be added in the future, the mime types
  62     are stored in an array so that an awk or other script can automatically
  63     generate the code to make the array.
  64  
  65     Usage:
  66  
  67         First an instance of the mimetype class must be created, then the
  68      getType method should be called with the filename.  It will return
  69      the mime type, an example follows.
  70      
  71     Example:
  72  
  73        $mimetype = new mimetype();
  74        print $mimetype->getType('acrobat.pdf');
