Alternative Control Structures

Thanks.

Still I don't understand why can't I echo like this:

Normally to echo, or print out a variable you would do this:
<?php echo $variable; ?>

With the alternative syntax you can instead do it this way:
<?=$variable?>

So in my case:

<?php echo $r->contents; ?>

<?= $r->contents?> don't work.
