This has no effect using curly braces or the more verbose statements:
You are strongly encouraged to always use curly braces even in
situations where they are technically optional. Having them
increases readability and decreases the likelihood of logic errors
being introduced when new lines are added.
http://drupal.org/node/318
This would apply with either method. The closing braces are put in place so
that when you want to add a new line to a statement it is easy:
<?php
if(true) {
line 1
} ?>
Which could easily be:
<?php
if(true):
line 1;
endif; ?>
Instead of:
<?php
if(true)
line 1
?>
However I agree for readabilities sake please use curly braces instead of
verbose statements unless you are templating.
