All projects in phpCollab follow a project lifecycle methodology, meaning that they are broken down into phases, then tasks, then subtasks. Your system administrator can customize these phases, in terms of number, order, and names. When you create the project, the "Enable Phases" type you choose will automatically create the pre-determined set of phases in your new project (Note: you can also choose not to enable phases at all.)

You can edit the information pertaining to a particular phase by clicking on the name of the phase in the "Phases" section of the main "Project" Page for that project, and then clicking the Edit button when you reach the "Phase" Page. You can also select the checkbox next to the phases's name and then click the Edit button above the list.
