我有这样的代码，它从XML文件中获取其他变量的值。这目前工作之前，我清理了代码，现在我不知道为什么它不工作。它如何工作是接受变量并基于该变量的值创建颜色。然后，我在这种情况下采用新的变量$ stormScale并将其分配给CSS类，以便像这样显示该单元格的颜色。PHP开关没有输出。
$td4Style = "{$sbrdr}; {$bbrdr}; padding: 2px 6px 6px 6px; background-color:{$stormScale};";
然后，我拿那个类，并使用它，当其他数据的表被输出像这样。
$tData .= " <tr><td style='{$td4Style}'> </td></tr>\n";
此开关是假设分配的颜色基于价值，但它现在不工作，我不知道为什么或我失踪。
$stormScale = '';
switch($ef)
{
case '0':
$stormScale = 'rgba(0, 255, 255, 0.2)';
break;
case '1':
$stormScale = 'rgba(0, 0, 255, 0.1)';
break;
case '2':
$stormScale = 'rgba(0, 255, 0, 0.2)';
break;
case '3':
$stormScale = 'rgba(255, 255, 0, 0.1)';
break;
case '4':
$stormScale = 'rgba(255, 153, 51, 0.2)';
break;
case '5':
$stormScale = 'rgba(255, 0, 0, 0.2)';
break;
}
下面是完整的代码。我希望我已经提供了足够的信息。我错过了什么？

为什么不只是使用类和风格的CSS _in CSS_？ – elclanrs 2013-05-09 04:51:15
您在表格显示中使用'$ stormScale'的位置？我找不到你在这里粘贴的代码。 – Roopendra 2013-05-09 04:56:36
@elclanrs 1.单元格颜色不是静态的，它们是根据分配给表的数据值动态创建的。 2.这是我正在开发的一个脚本，它是一个将与其他人共享的模板集的附加内容。所以它需要非常简单的即插即用，而且不需要很多设置。上传并去。 3.使用内联样式可以实现这一点，因为样式不会是全局的，只会为CSS添加不必要的样式。 – Texan78 2013-05-09 05:29:17
