If Snippet: Array

I'm using the If snippet to check placeholders, one at a time. Works great.

Now I need to check an array of 3 placeholders, and only if all 3 are empty return a message. Looking at the If docs I understand the basic idea of the array example, but what I can't figure out is how to ensure all 3 placeholders are empty (instead of either/or) before printing my "empty message".

[[If?
   &subject=`[[*id]]`
   &operator=`inarray`
   &operand=`6,11,12`
   &then=`Show this if all 3 are empty`
   &else=``
]]

[[If?
    &subject=`[[*placeholder-1]][[*placeholder-2]][[*placeholder-3]]`
    &operator=`empty`
    &then=`Show this if all 3 are empty`
    &else=``
]]

I'm trying to use the If extra to identify words in a text array, but I find that it only works for numbers. How can I solve this problem?

For example:

[[!If?
   &subject=`birds`
   &operator=`inarray`
   &operand=`dogs, birds, cats`
   &then=`Birds`
   &else=`No birds`
]]

I solved my own question, it's possible to use the ifEval add-on instead to utilize "strpos" like this:

[[!ifEval? &input=`stripos("dogs, birds, cats", "birds")  !== false` &contentTrue=`Birds` &contentFalse=`No birds`]]
