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

Answer 1

使用 str_replace

<?php 

$currenturl=$_SERVER['REQUEST_URI'];
$currenturl=str_replace('/ca','',$currenturl); // I have added it here

?>

<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>

Answer 2

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。尝试以下代码：

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

Answer 3

$_SERVER['REQUEST_URI']由php提供，它不是你可以从你的htaccess文件中删除的东西。你需要在php中删除它：

<?php $currenturl=preg_replace('#(/[a-z]{2})?(/.*)#','${2}',$_SERVER['REQUEST_URI']); ?>

Answer 4

我使用了Shankar Damodaran的稍微修改过的例子 -

<?php
    $currenturl = $_SERVER['REQUEST_URI'];
    $languge_folder  = array('/en', '/ru', '/ua');
    $currenturl_en = str_replace($languge_folder,'',$currenturl); 
    $currenturl_ru = str_replace($languge_folder,'',$currenturl);
    $currenturl_ua = str_replace($languge_folder,'',$currenturl);
?>
          <select id="select-language" onchange="window.location.href=this.value">
             <option value="/ua/<?php echo $currenturl_ua; ?>"  selected="selected">Ukrainian</option>
             <option value="/ru/<?php echo $currenturl_ru; ?>" >Russian</option>
             <option value="/en/<?php echo $currenturl_en; ?>" >English</option>
          </select>

从$ _SERVER ['REQUEST_URI']中删除父文件夹;
