제어 구조의 대체 문법
PHP는 제어 구조를 위해 대체 문법을 제공한다; 즉 if, while, for, foreach, 그리고 switch. 각 경우에 대체 문법의 기본형태는 괄호열기를 콜른 (:)으로 대체하고 괄호닫기는 각각 endif;, endwhile;, endfor;, endforeach;, 또는 endswitch;으로 대체한다.
<?php if ($a == 5): ?>
A는 5와 같다
<?php endif; ?>
위 예에서는 대체 문법으로 쓰여진 if구문안에 "A는 5와 같다" HTML 블록이 포함되어있다. 이 HTML 블록은 $a가 5와 같을때만 출력될것이다.
대체 문법은 else와 elseif문에도 적용이 된다. 다음은 elseif와 else문 과 같이 있는 if문 절의 대체 형태이다:
<?php
if ($a == 5):
echo "a는 5와 같다";
echo "...";
elseif ($a == 6):
echo "a는 6과 같다";
echo "!!!";
else:
echo "a는 5도 아니고 6도 아니다";
endif;
?>

It seems to me, that many people think that
<?php if ($a == 5): ?>
A ist gleich 5
<?php endif; ?>
is only with alternate syntax possible, but
<?php if ($a == 5){ ?>
A ist gleich 5
<?php }; ?>
is also possible.
alternate syntax makes the code only clearer and easyer to read

The control structure should be like in BASIC languages:
<?php
if ($a == 12):
echo "a is 12\n";
end if;
while (true):
echo "loop loop loop\n";
end while;
?>
or just use end operator like in Ruby
<?php
if ($a == 12):
echo "a is 12\n";
end;
while (true):
echo "loop loop loop\n";
end;
?>

Hello , when you going to make a script , you must try easist way to do and fastest way to parse ..
using alternative-syntax is very useful to shorten your code
e.g :
If you want to do:
<?php
$a=1 ;
if ($a==1) {
echo "<table border=1><tr><td>$a is equal to one </td></tr></table> " ;
}
?>
You can do it using alternative-syntax as following :
<?php
$a=1 ;
if ($a==1) :?>
<table border=1><tr><td><?echo $a ;?> is equal to one </td></tr></table>
<?php endif ; ?>
So the HTML code Won't excuted until the condition is true

If you wan't to use the alternative syntax for switch statements this won't work:
<div>
<?php switch($variable): ?>
<?php case 1: ?>
<div>
Newspage
</div>
<?php break;?>
<?php case 2: ?>
</div>
Forum
<div>
<?php break;?>
<?php endswitch;?>
</div>
Instead you have to workaround like this:
<div>
<?php switch($variable):
case 1: ?>
<div>
Newspage
</div>
<?php break;?>
<?php case 2: ?>
</div>
Forum
<div>
<?php break;?>
<?php endswitch;?>
</div>

[EDITOR'S NOTE: reference to deleted note removed]
The end_; structure sometimes makes it easier to tell which block statement end you are looking at. It's much harder to tell which nested block a } belongs to than an end_;

If it needs saying, this alternative syntax is excellent for improving legibility (for both PHP and HTML!) in situations where you have a mix of them.
Interface templates are very often in need of this, especially since the PHP code in them is usually written by one person (who is more of a programmer) and the HTML gets modified by another person (who is more of a web designer). Clear separation in such cases is extremely useful.
See the default templates that come with WordPress 1.5+ (www.wordpress.org) for practical and smart examples of this alternative syntax.
