52: 
53:     <p>We use the AJAX-enabled "Hello World" example to explain how you can make single file <strong>QForm</strong> pages.
54:         Note that this approach is <em>not always recommended</em> -- keeping the display logic (.php) file separate
55:         from the presentation HTML template (.tpl.php) file helps to enforce the good design and separation of display
56:         logic from the presentation layer (e.g. keeping the V and C separate in MVC).</p>
57: 
58:     <p>However, there may be times when you want a simpler architecture of single-file forms, or you
59:         are making some very simple <strong>QForm</strong> pages and you do not want to deal with the overhead
60:         of the dual-file format.  This example shows how you can use built-in PHP functionality to code your
61:         <strong>QForm</strong> as a single .php file.</p>
62: 
63:     <p>Feel free to <strong>View Source</strong> (the button below) to see how this is done.</p>
