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;
?>
