[PHP] File Upload Question

[Vail, Warren]

Perhaps this is more about HTML than PHP, but the PHP $_FILES var seems to
be set up to allow a list of files to be uploaded.  How does one get the
pop-up window to allow a user to select (ctrl-click or whatever) multiple
files in the same pop-up window?  Everything I have tried has left the user
restricted to selecting one file only.
 
thanks in advance.
