Alternative syntax for control structures
(PHP 4, PHP 5)
PHP offers an alternative syntax for some of its control structures; namely, if, while, for, foreach, and switch. In each case, the basic form of the alternate syntax is to change the opening brace to a colon (:) and the closing brace to endif;, endwhile;, endfor;, endforeach;, or endswitch;, respectively.
<?php if ($a == 5): ?>
A is equal to 5
<?php endif; ?>
In the above example, the HTML block "A is equal to 5" is nested within an if statement written in the alternative syntax. The HTML block would be displayed only if $a is equal to 5.
The alternative syntax applies to else and elseif as well. The following is an if structure with elseif and else in the alternative format:
<?php
if ($a == 5):
echo "a equals 5";
echo "...";
elseif ($a == 6):
echo "a equals 6";
echo "!!!";
else:
echo "a is neither 5 nor 6";
endif;
?>
Note:
Mixing syntaxes in the same control block is not supported.

I feel compelled to give a more elegant way using heredoc than the other comment:
<ul>
<?php foreach($list as $item): echo
<<<ITEM
<li id="itm-$item[number]">Item $item[name]</li>
ITEM;
endforeach; ?>
</ul>
Which works better with multi line blocks, as you only need one overall php tag.
(please don't omit the closing </li> tag despite it being legal, personal preference)
