    // %        note 1: There are a few unsolved issues with this function. Summarizing:
    // %        note 1: converts all the special characters (e.g. tags) to HTML entities, 
    // %        note 1: thus reducing the usability of HTML formatting in echo().
    // %        note 1: 
    // %        note 1: InnerHTML() is better because it works (and it's fast),   
    // %        note 1: but using innerHTML on the BODY is very dangerous because
    // %        note 1: you will break all references to HTMLElements that were done before
    // %        note 1: 
    // %        note 1: There's no good place for a package like http://innerdom.sourceforge.net/
    // %        note 1: inside php.js
    // %        note 1:
    // *     example 1: echo('Hello', 'World');
    // *     returns 1: null
