// I used the same object name as the similar program written
// by David Sklar at http://px.sklar.com/code.html?code_id=15
// I couldn't get his to work for array data for some reason and
// his variable names were sort of abstract for my tastes, so
// I developed this one.  It also strips tags, and this code is based
// upon some stuff I found at the php.net site by:
//  tomjr@tx3.net
//  jkeppens@xs4all.be
//  dsalada@adventassociates.com
// so it is not totally my doing.  I hope it is useful to you.  Basically,
// calling it will
// make hidden tags for any post, get, or cookie data that it passed
// to the php script that calls it.  It strips the tags of the values that
// it puts into the hidden fields, but it does not strip the tags of the
// variables that PHP creates for you from the HTTP_POST_VARS and so forth.
// I haven't tested the get and cookie stuff yet, but it probably works.
