Pm Wiki:

For web developers who host several clients on a single server, Per Group Customizations allow a single Pm Wiki installation to handle all sites with customization handled at the group.php level. In order to view new Pm Wiki sites, the following steps must be taken:

• Define the new Group.php customizations
• Set the index.php file for the group to point to the Group.php file.
  • <?php header("Location: http://www.domainname.com/path/to/wiki/Groupname/pagename"); ?>
• Create wiki file to point to the pmwiki.php file.
  • <?php chdir("../pmwiki"); include("pmwiki.php"); ?>
• Create .htaccess file:
  • <Files wiki>
  • SetHandler application/x-httpd-php
  • </Files>
