最简单的方法交替行颜色在PHP / HTML？ [英] Easiest way to alternate row colors in PHP/HTML?

问题描述

这是我的一个PHP示例。任何人都可以找到一个更短/更简单的方法来做到这一点？

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>

其他语言的示例也很有趣。

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

推荐答案

从根本上 - 没有。这就是那么容易。你可以重写它有点更短/更清洁，但想法会一样。这是我写的：

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>";
