title: Insert line break after every two rows of database
body: <p>I have a little script that prints a certain amount of rows in a mysql database. </p>
  
  <p>Is there any way to make it so that after every <em>second</em> row it prints, there is a line break inserted? </p>
  
  <p>Adding a line break after every row is simple, but I don't know how to add one after every other row. Is that possible?</p>
