In PHP, there are a lot of alternative syntax. It can improve the legbility of your code.

---

if, while, for, foreach, switch

The alternatice syntax in control structures is to remove the openning brace instead of a colon and closing with endif, endwhile, endfor, foreach, and endswitch.

if, endif

<?php if ($a == 5): ?>
A is equal to 5
<?php endif; ?>

while, endwhile

<?php while ($a < 5): ?>
<?php print $a++; ?>
<?php endwhile; ?>

Output:

01234

Remember, do not use any indent in this case.
