---|
| 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. |

---|
| 48 | |
---|
| 49 | // Use the PRE_VALID header. This means less output source since we don't have to output |
---|
| 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   |
---|
| 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(); |
