Question

I’ve got an array:

(
[0]
   (
      [room_num] => 1
      [is_event] => true
      [date] => '01/01/2013'
   )
[1]
   (
      [room_num] => 2
      [is_event] => false
      [date] => ''
   )
[2]
   (
      [room_num] => 3
      [is_event] => false
      [date] => ''
   )
[3]
   (
      [room_num] => 1
      [is_event] => false
      [date] => ''
   )
)

What I’d like to do is filter the results so that where is_event = true supersedes is_event = false. My returned array would look like:

(
[0]
   (
      [room_num] => 1
      [is_event] => true
      [date] => '01/01/2013'
   )
[1]
   (
      [room_num] => 2
      [is_event] => false
      [date] => ''
   )
[2]
   (
      [room_num] => 3
      [is_event] => false
      [date] => ''
   )
)

Sort of like array_unique except ON a certain value.

Is there a built in function for this?

Answer 1

There’s no built in function

You’ll have to loop and check yourself
