Question

我编写了检查用户语言并打开文件的代码（如果用户的语言为英语，则打开en.php，依此类推）。我添加了一个选项，可以在设置中更改您的语言，但这不起作用。

# Checks for user's language
if (isset($_COOKIE['lang'])) {
   $lang = substr(explode(',',$_SERVER['HTTP_ACCEPT_LANGUAGE'])[0],0,2)?:'en';
   if ($lang = $_COOKIE['lang']){
         $lang = $_COOKIE['lang'];
         setcookie("lang",$lang,time()+3650*24*60*60);
         $_SESSION['lang'] = $lang;
     } else {
       # $lang = substr(explode(',',$_SERVER['HTTP_ACCEPT_LANGUAGE'])[0],0,2)?:'en';
        setcookie("lang",$lang,time()+3650*24*60*60);
        $_SESSION['lang'] = $lang;
     }
   }

if ($lang === "en") {
        require 'translations/en.php'; # ENGLISH
     } # also every other language is included in elseif

<!-- The form goes to that same page but at the beginning there are files included -->
<form method="post" action="settings.php" id="form2" name="form2">
<select class="settingsselect" name="language_select">
<option disabled selected>Select a Language</option>
<option value="something">some language</option>
</select>
</form>
<button class="updatesettings" type="submit" id="updatesettings" name="updatesettings" form="form2">Update Settings</button>

# Update code
if (isset($_POST['updatesettings'])) {
    $lang = $_POST['language_select'];
    setcookie("lang",$lang,time()+3650*24*60*60);
    $_SESSION['lang'] = $lang;
}

#files included in the beginning

require 'language_change.php';
require 'password_check.php';
require 'translation.php';

您提供的php文件的一些示例是近似的且充满语法错误，由于您的方法不正确，可能无法正常工作，请尝试更改php的逻辑...并由于我们无法猜测出什么问题（您的code应该从头开始重写），因此我创建了一个php示例，说明如何工作，请不要复制它，但要从中获取启发，谢谢
