php - 从 $_SERVER ['REQUEST_URI' 中删除父文件夹];

Question

我想删除 $_SERVER['REQUEST_URI'] 输出的第一个文件夹；

// I use it as language switcher in my website, here's how it works:

<?php $currenturl=$_SERVER['REQUEST_URI']; ?>

<a href="https://mysite.com/<?php echo $currenturl ?>">United States</a>
<a href="https://mysite.com/ca<?php echo $currenturl ?>">Canada</a>
<a href="https://mysite.com/br<?php echo $currenturl ?>">Brasil</a>

问题是，例如在加拿大，它输出:

https://mysite.com/ca/ca/mypage

应该是

https://mysite.com/ca/mypage

好吧，我认为您正在尝试获取路径的文件名而不是删除第一个文件夹。试试下面的代码:

$currenturl=basename($_SERVER['REQUEST_URI']);
