HTML pages can contain Hypertext Processor scripts (PHP ,
http://www.php.net/). In the pages, the scripts are included
in <?php ... ?>. It is recommended to use
php as content type, if only a small part of the website is
dynamic. If all or most of the pages have dynamic content,
html can be used as content type as an alternative.
The webserver commonly used to dynamically generate content using PHP is
the Apache webserver plus a special module (mod_php, which is
part of the PHP distribution). The module will be loaded if it is added
to the httpd.conf configuration file, and the dynamic content
is passed to the module by assigning the
application/x-httpd-php MIME type to it.
For the preview, a separate Apache webserver must be configured in
accordance with the live server. The preview server is required to deliver
a directory accessible by the GUI (declare it in the
httpd.conf file as <Directory> and direct
it to an URL by means of an alias).
