Subject: Extract common entries in two arrays

Hi, how to get an array with just common entries from two arrays?:

  array1 = ["q", "w", "e", "r", "t", "y"]
  array2 = ["w", "t", "z"]

I want to get:

  array_common = ["w", "t"]

I don0t find an ellegant and fast way to get it. Any help?
Thanks a lot.
