You can use Modulo operator of PHP. For example $i%3 divides the variable by 3 gives reminder of the divider operation as return value. So, in your case it will always gives 1 for the values 1, 4, 7, 10, 13 ......
Please check the below code,

<?php if ($i%3 == 1){ ?> first <?php } ?>

Please refer, http://php.net/manual/en/language.operators.arithmetic.php

  • You should add an explanation to the answer, not just "try". – M. Eriksson May 15 '17 at 05:41
  • it wasn't when I commented. But that's a good rule of thumb... always add an explanation. – M. Eriksson May 15 '17 at 05:43

    Sure @Magnus. I will do that in my answers – manian May 15 '17 at 05:43
  • @Magnus, Not sure if it is good idea to delete my answer. I will leave my answer to be here but with explanation. I am not worrying about the downvotes. I already have kept few of my answers with negative votes, un-deleted because I think I posted correct answers. Your inputs please? – manian May 15 '17 at 05:54
  • Your solution is correct, it was just missing an explanation (it's important so the OP understands why this is correct so he/she can modify it to fit better). Now it's spot in.. upvote worhty. :) – M. Eriksson May 15 '17 at 06:35
