How to implement reverse Star pattern in php

In interview, interviewer asked me to write program for reverse star pattern. it was just to check my logic. in this post I am sharing this program.

Inner loop prints line wise and outer loop prints column wise.

<?php
           for($i = 10; $i > 0 ; $i--){
                  for($j = 0; $j < $i ; $j++){
                         echo '*';
                  }
                  echo '<br/>';
            }
?>

Output of the above code will be
