I want to create an overview of the first dates of every event. So the event-title must be unique. My idea was to create a helper-function where I loop over the result of my query and check the title of every item. To make sure every title passes only once, I want to push the title into an array ($checklist). If it does not exist, I add that item to the result-array. If it does, just continu
