Note that the alternative syntax might not work if short_open_tag is set to 'off' in your php.ini file.
Sintaxis Alternativa de Estructuras de Control
PHP ofrece una sintaxis altenativa para alguna de sus estructuras de control; a saber, if, while, for, y switch. En cada caso, la forma básica de la sintaxis alternativa es cambiar abrir-llave por dos puntos (:) y cerrar-llave por endif;, endwhile;, endfor;, or endswitch;, respectivamente.
<?php if ($a==5): ?>
A es igual a 5
<?php endif; ?>
En el ejemplo de arriba, el bloque HTML "A es igual 5" se anida dentro de una sentencia if escrita en la sintaxis alternativa. El bloque HTML se mostraría solamente si $a fuera igual a 5.
La sintaxis alternativa se aplica a else y también a elseif. La siguiente es una estructura if con elseif y else en el formato alternativo:
<?php
if ($a == 5):
print "a es igual a 5";
print "...";
elseif ($a == 6):
print "a es igual a 6";
print "!!!";
else:
print "a no es ni 5 ni 6";
endif;
?>

If you wan't to use the alternative syntax for switch statements this won't work:
<div>
<?php switch($variable): ?>
<?php case 1: ?>
<div>
Newspage
</div>
<?php break;?>
<?php case 2: ?>
</div>
Forum
<div>
<?php break;?>
<?php endswitch;?>
</div>
Instead you have to workaround like this:
<div>
<?php switch($variable):
case 1: ?>
<div>
Newspage
</div>
<?php break;?>
<?php case 2: ?>
</div>
Forum
<div>
<?php break;?>
<?php endswitch;?>
</div>

In response to spa:
Yeah, that's for sure! Seems so obvious, but remains a tough sell... I avoid the "Bracket Racket", and use it only where the (ahem) "Clearer Syntax" wasn't implemented.
A further improvement would be a "Noun-Verb" form of end structures. Such as:
if (...):
while (...):
...
if (...):
...
...
ifend;
...
whileend;
ifend;
This would make it yet another level of easier to tell which block end you're looking at. ;-)

[EDITOR'S NOTE: reference to deleted note removed]
The end_; structure sometimes makes it easier to tell which block statement end you are looking at. It's much harder to tell which nested block a } belongs to than an end_;

If it needs saying, this alternative syntax is excellent for improving legibility (for both PHP and HTML!) in situations where you have a mix of them.
Interface templates are very often in need of this, especially since the PHP code in them is usually written by one person (who is more of a programmer) and the HTML gets modified by another person (who is more of a web designer). Clear separation in such cases is extremely useful.
See the default templates that come with WordPress 1.5+ (www.wordpress.org) for practical and smart examples of this alternative syntax.
