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;
?>
