These are the templates for all new PHP files. There is a different template depending on whether you file is able to be publicly hittable or not.

This project uses PHPDoc for API documentation. This project is also licensed under the GPL, which causes some header bloat (it is a requirement of licensing your program under the GPL, see http://www.gnu.org/copyleft/gpl.html ).

Notes:

  • Omit the closing php tag "?>"
  • Catalyst employees should assign copyright to "Catalyst IT Ltd", if they are working on the project in company time.
  • The author field should always be a person (or more than one), not a company
