lt  php  first   reset  arr nav      Get the first element  last    end  arr nav        Get the last element    Ensure that we have a first element and that it s an array if is array  first          first  class      first        Ensure we have a last element and that it differs from the first if is array  last   amp  amp   last      first        last  class      last       Now you could just echo the class inside you html-generator  Would probably need some kind of check to ensure that the class is set  or provide a default empty class to the array

If you mean the first and last entry of the array when talking about a first and a last  it goes like this   foreach   arr nav as  inner array        echo reset  inner array     apple  orange  pear     echo end  inner array     My Apple  View All Oranges  A Pear     arrays in PHP have an internal pointer which you can manipulate with reset  next  end  Retrieving keys values works with key and current  but using each might be better in many cases
