一段PHP代码!

本帖最后由 u010250831 于 2014-04-26 22:46:36 编辑  if(is_array($today)): $i = 0; $__LIST__ = $today;if( count($__LIST__)==0 ) : echo "" ;else: foreach($__LIST__ as $key=>$vo): ++$i;$mod = ($i % 2 )
?>

上面的代码是什么写法？“:”是什么符？懂得大神详细讲解下！
------解决方案--------------------
php 流程控制有两种语法结构。一种用大括号表示语句块，一种用冒号表示语句块。
大括号表示语句块的用得较多，这里就不说了。
使用冒号“：”来代替左边的大括号“{”；使用endif;、endwhile;、endfor；、endforeach；和endswitch；来代替右边的大括号“}”。

例如以下两段程序是一样的

$a=1;
$b=2;

if($a==$b){
    echo 'a=b';
}else{
    echo 'a!=b';
}
Copy after login



$a=1;
$b=2;

if($a==$b)
    :echo 'a=b';
else
    :echo 'a!=b';
endif
Copy after login

------解决方案--------------------
