我有这个代码，它从另一个从XML文件中获取的变量中获取值。这在我清理代码之前目前有效，现在我不知道它为什么不起作用。如何工作是获取变量并根据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，以便像这样显示单元格的颜色。
$td4Style = "{$sbrdr}; {$bbrdr}; padding: 2px 6px 6px 6px; background-color:{$stormScale};";
然后我把那个类当用于输出其他数据的表时使用它。
$tData .= " <tr><td style='{$td4Style}'> </td></tr>\n";
此开关假设根据值分配颜色，但它现在不起作用，我不知道为什么或我缺少什么。
$stormScale = '';
switch($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;
}
这是完整的代码。我希望我提供了足够的信息。我错过了什么？

在运行期间，$ ef的值是多少。可能有助于抛出
default:
print_r($fatalities);
die("unhandled ef value ".$ef);
break;
进入switch语句，以便更轻松一点
更有可能的是，simplexml不会给你一个数组或者你不期望$ ef值的东西。同样使用simplexml，对返回的数据进行显式转换总是一个好主意。即switch ((string)$ef)

您在创建变量之前分配变量。像这样改变你的剧本
