-
-    // 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_VALID 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.
-    // HEADER_PRE_VALID puts the <pre> tag inside the list items (<li>) thus producing valid HTML markup.
-    // HEADER_PRE puts the <pre> tag around the list (<ol>) which is invalid in HTML 4 and XHTML 1
-    // HEADER_DIV puts a <div> tag arount the list (valid!) but needs to replace whitespaces with &nbsp
-    //            thus producing much larger overhead. You can set the tab width though.
-    $geshi->set_header_type(GESHI_HEADER_PRE_VALID);
-
-    // 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('font: normal normal 90% monospace; color: #000066; border: 1px solid #d0d0d0; background-color: #f0f0f0;', false);
-
-    // 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_code_style('color: #000020;', true);
-
-    // 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.
