Multiple PHP tags

Is there a difference between:

<?php echo "n" ?>
<?php echo "i" ?>
<?php echo "g" ?>

and

<?php
    echo "t";
    echo "i";
    echo "t";
?>

in terms of time and resources used?

  1. If you in doubts - measure
  2. Always prefer readable solution

My first thought is maybe.

That being said, I used to code for a site that took thousands of hits a second, and tried both ways. I did not see any noticeable difference. I have no empirical evidence, but in my tests on a high volume site, it seems to make no difference.
