Update to my Object Oriented HTML class

I removed most of the Actionscript like functions because it can not be changed after the server has sent it to the client.  I am testing some HTML class extensions and will post them soon.


<?php

/**
 * Description of HTML
 *  -- OO-HTML 1.1 --
 * - Removed some methods that it didnt make sense to have.
 * - Removed array key name requirement on addChild
 *
 * @author Joseph Tveter
 *
 * Class to allow HTML to be eaisly written in native php
 * It will also work for building xml
 *
 * The $cmd string is the tag command such as a,div,html
 *
 * The $vals array holds a list of value commands for the html tag
 *
 * The $children array holds a list of children of the tag.  They will be placed in decending order, so a tag at [1] will come before a tag at [2]
 *
 * To print the string call HTML();
 * example:
 *
 * $mydiv = new HTML('div');
 * $mydiv->addValue('name', 'mydiv');
 * $mydiv->addChild('Hello World');
 * echo $mydiv->HTML();
 *
 * This will print.
 * --------------------
 * <div name='mydiv'>
 * Hello World
 * </div>
 * ----------------------
