43    // First the initialisation: source code to highlight and the language to use. Make sure
44    // you sanitise correctly if you use $_POST of course - this very script has had a security
45    // advisory against it in the past because of this. Please try not to use this script on a
46    // live site.
47    $geshi = new GeSHi($_POST['source'], $_POST['language']);
48
49    // Use the PRE_VALID header. This means less output source since we don't have to output &nbsp;
50    // everywhere. Of course it also means you can't set the tab width.
51    // HEADER_PRE_VALID puts the <pre> tag inside the list items (<li>) thus producing valid HTML markup.
52    // HEADER_PRE puts the <pre> tag around the list (<ol>) which is invalid in HTML 4 and XHTML 1
53    // HEADER_DIV puts a <div> tag arount the list (valid!) but needs to replace whitespaces with &nbsp
54    //            thus producing much larger overhead. You can set the tab width though.
55    $geshi->set_header_type(GESHI_HEADER_PRE_VALID);
56
57    // Enable CSS classes. You can use get_stylesheet() to output a stylesheet for your code. Using
58    // CSS classes results in much less output source.
59    $geshi->enable_classes();
60
61    // Enable line numbers. We want fancy line numbers, and we want every 5th line number to be fancy
62    $geshi->enable_line_numbers(GESHI_FANCY_LINE_NUMBERS, 10);
63
64    // Set the style for the PRE around the code. The line numbers are contained within this box (not
65    // XHTML compliant btw, but if you are liberally minded about these things then you'll appreciate
66    // the reduced source output).
67    $geshi->set_overall_style('font: normal normal 90% monospace; color: #000066; border: 1px solid #d0d0d0; background-color: #ffffff;', false);
68
69    // Set the style for line numbers. In order to get style for line numbers working, the <li> element
70    // is being styled. This means that the code on the line will also be styled, and most of the time
71    // you don't want this. So the set_code_style reverts styles for the line (by using a <div> on the line).
72    // So the source output looks like this:
73    //
74    // <pre style="[set_overall_style styles]"><ol>
75    // <li style="[set_line_style styles]"><div style="[set_code_style styles]>...</div></li>

82    // note that classes must be enabled for this to work.

88    // appear inside it.
