    // Here's a free demo of how GeSHi works.
    
    // First the initialisation: source code to highlight and the language to use. Make sure
    // you sanitise correctly if you use $_POST of course - this very script has had a security
    // advisory against it in the past because of this. Please try not to use this script on a
    // live site.
	$geshi =& new GeSHi($_POST['source'], $_POST['language']);
    
    // Use the PRE header. This means less output source since we don't have to output &nbsp;
    // everywhere. Of course it also means you can't set the tab width.
	$geshi->set_header_type(GESHI_HEADER_PRE);
    
    // Enable CSS classes. You can use get_stylesheet() to output a stylesheet for your code. Using
    // CSS classes results in much less output source.
	$geshi->enable_classes();
    
    // Enable line numbers. We want fancy line numbers, and we want every 5th line number to be fancy
	$geshi->enable_line_numbers(GESHI_FANCY_LINE_NUMBERS, 5);
    
    // Set the style for the PRE around the code. The line numbers are contained within this box (not
    // XHTML compliant btw, but if you are liberally minded about these things then you'll appreciate
    // the reduced source output).
	$geshi->set_overall_style('color: #000066; border: 1px solid #d0d0d0; background-color: #f0f0f0;', true);
    
	// Set the style for line numbers. In order to get style for line numbers working, the <li> element
    // is being styled. This means that the code on the line will also be styled, and most of the time
    // you don't want this. So the set_code_style reverts styles for the line (by using a <div> on the line).
    // So the source output looks like this:
    //
    // <pre style="[set_overall_style styles]"><ol>
    // <li style="[set_line_style styles]"><div style="[set_code_style styles]>...</div></li>
    // ...
    // </ol></pre>
	$geshi->set_line_style('font: normal normal 95% \'Courier New\', Courier, monospace; color: #003030;', 'font-weight: bold; color: #006060;', true);
	$geshi->set_code_style('color: #000020;', 'color: #000020;');

    // Styles for hyperlinks in the code. GESHI_LINK for default styles, GESHI_HOVER for hover style etc...
    // note that classes must be enabled for this to work.
	$geshi->set_link_styles(GESHI_LINK, 'color: #000060;');
	$geshi->set_link_styles(GESHI_HOVER, 'background-color: #f0f000;');

    // Use the header/footer functionality. This puts a div with content within the PRE element, so it is
    // affected by the styles set by set_overall_style. So if the PRE has a border then the header/footer will
    // appear inside it.
