  what's the most comprehensive way for a PHP script to determine the
mime/content type of an incoming stream of bytes?  i'd like to assume
that i will receive nothing more than the bytes -- no filename, no
extension, etc.

  i see things like getimagesize(), mime_content_type() (which is
listed as deprecated), the FileInfo structure, etc.  any
recommendations on what the standard is these days?  i'd like to be
able to recognize and categorize as many image, audio and video
formats as possible.
