Alternative syntax for control structures

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;
?>

See also while, for, and if for further examples.

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)
