Php 比使用开关盒更容易改变颜色

，我使用开关盒为导航栏的活动链接添加颜色

我首先声明了一个数组

$case

，其中包含导航栏中所有可能的链接。然后，我检查它是否是在其中一个页面上单击的函数（如果查询字符串不是空的），以及它是否被放入

$case

数组中（以防止在单击其他页面内的其他链接时更改颜色）

如果为true，

$current

将获得一个类似于

docs\u zamo

或

akuut\u wgakuut-->FILENAME\u查询的值。

我只想在之前声明颜色时更改它（在$case数组中），否则，它将只是文件名（不带“.php”）

我觉得这段代码相当笨拙。还有别的方法做这项工作吗？我对PHP相当陌生。我想；如果有一个函数检查开关内是否存在一个case，那么我就不需要$case数组，因为我已经声明了开关内是否存在链接

检查是否为文件名的代码\u查询链接：

$case = array("index","medica","praesidium","akuut","sponsors","docs","docs_zamo","kalender","evenementen","fotos","werking","jaarraden","akuut_wgakuut","onderwijs","sociaal","sport","werkgroepen","eerstejaars","international",);

if (($_SERVER['QUERY_STRING'] != "") && (in_array(basename($_SERVER['PHP_SELF'],'.php') ."_". str_replace('actie=','',$_SERVER['QUERY_STRING']),$case) == true)) {
    $current = basename($_SERVER['PHP_SELF'],'.php') ."_". str_replace('actie=','',$_SERVER['QUERY_STRING']);
}
else {$current = basename($_SERVER['PHP_SELF'],'.php');}

$id = array("","","","","","","","","","","","","","","","","","","");

for（$i=0；$ior有人能改进我的代码吗，即使它能工作呢？$case[6]：$id[18]=“class='here'”；break；原始代码中的case？这很有趣，谢谢！关于$case[6]：$id[18]->我可以更改数组中的对应位置：）你的循环代码错了，但我设法解决了：）for（$i=0；$iSorry，这是我的错误，我已经纠正了。）
