在 PHP/HTML 中交替行颜色的最简单方法?

这是我的一个 PHP 示例.谁能找到更短/更简单的方法来做到这一点?

<代码><div class="<?=($c++%2==1)?'odd':NULL?>"><?=$post?>
<?}?><风格>.odd{背景颜色:红色；}</风格>

其他语言的示例也会很有趣.

解决方案

从根本上说 - 没有.这很容易.你可能会改写得更短/更简洁，但想法是一样的.我是这样写的:

$c = true;//我们不要忘记初始化我们的变量，好吗?foreach($posts 作为 $post)echo '<div'.(($c = !$c)?' class="odd"':'').">$post</div>";

Here's a PHP example of mine. Can anyone find a shorter/easier way to do this?

<? foreach($posts as $post){?>
    <div class="<?=($c++%2==1)?‘odd’:NULL?>">
        <?=$post?>
    </div>
<? }?>

<style>
    .odd{background-color:red;}
</style>

Examples in other languages would be fun to see as well.

解决方案

Fundamentally - no. That's about as easy as it gets. You might rewrite it a bit shorter/cleaner, but the idea will be the same. This is how I would write it:

$c = true; // Let's not forget to initialize our variables, shall we?
foreach($posts as $post)
    echo '<div'.(($c = !$c)?' class="odd"':'').">$post</div>";
