I'm curious if there is a get() function equivalent to this or some way to retrieve information from the URL. Thanks for your help!

@Jeffrey - there is no a helper function for the GET data yet, but there is the getField() method in the Request class. Example: Phpr::$request->getField('name') or Phpr::$request->getField('name', 'default value').

I am trying to get an array from POST. I see there is a post_array_item() method, but I don't want to get elements from an associated array. I want to get a full indexed array. I have several checkboxes with the same name but different values. I know if I used $_POST['my_name'] I should get an array. Should I be getting the same from post('my_name')?

@Silas Bondrup-Nielsen post() function should be suitable for you. This function is a wrapper for the $_POST array and works similarly. The only difference between post() and $_POST is that post() can return a default value if the key is not found in $_POST.
