There are 2 ways you can use the source code highlighting feature, however their ability to work depends on your installation. If you have configured Apache to use PHP as an ISAPI module, then by adding the following line to your configuration file you can use this feature: AddType application/x-httpd-php-source .phps
If you chose to configure Apache to use PHP as a CGI binary, you will need to use the show_source() function. To do this simply create a PHP script file and add this code: <?php show_source ("original_php_script.php"); ?>. Substitute original_php_script.php with the name of the file you wish to show the source of.
