Change language of site with a html button
提问by kensil
In PHP, I want to change the language (English, German, etc) of the site when clicking a button. Is this the right way to approach that problem?
在 PHP 中，我想在单击按钮时更改站点的语言（英语、德语等）。这是解决这个问题的正确方法吗？
<?php
$language;
if ($language == "en") {
include("headerEn.php");
} else {
include("header.php");
}
?>
<a href="index.php"><?php $language = "en"; ?>
<img src="images/language/languageNO.png"></a>
<a href="index.php"><?php $language = "no"; ?>
<img src="images/language/languageEN.png"></a>
What is the best way to change the language of the site and have it persist when the user returns?

you can do this by
你可以这样做
<a href="index.php?language=en">
<a href="index.php?language=no">
and get the languages and store them in cookie and include file according to cookie like
并获取语言并将它们存储在 cookie 中并根据 cookie 包含文件，例如
if ( !empty($_GET['language']) ) {
$_COOKIE['language'] = $_GET['language'] === 'en' ? 'en' : 'nl';
} else {
$_COOKIE['language'] = 'nl';
}
setcookie('language', $_COOKIE['language']);
and than
然后
if ( $_COOKIE['language'] == "en") {
include("headerEn.php");
} else {
include("header.php");
} ?>

To give a solution without changing your approach, You can do like this.
要在不改变方法的情况下提供解决方案，您可以这样做。
<?php
if(isset($_GET['language']))
$language = $_GET['language'];
else
$language = "";
if ($language == "en") {
include("headerEn.php");
} else {
include("header.php");
} ?>
<a href="index.php?language = en"><img src="images/language/languageNO.png"> </a>
<a href="index.php?language = no"><img src="images/language/languageEN.png"></a>
If you want to keep the selection, you can store this value in Database or Session.
如果要保留选择，可以将此值存储在数据库或会话中。
回答by fedorqui 'SO stop harming'
It is always good to have a default value, so that you never end up being in a no-language site.
有一个默认值总是好的，这样你就永远不会进入一个没有语言的网站。
$language = $_REQUEST["language"];
$default_header="myheaderXXX.php";
switch ($language) {
case "en":
include("headerEn.php");
break;
case "no":
include("header.php");
break;
default:
include($default_header);
}
And then create links like this:
然后创建这样的链接：
<a href="index.php?language=en">
<a href="index.php?language=no">

Try to save this $languagevalue to sessionvariable. When the page reloaded check that the session variable is set or not.
尝试将此$language值保存到会话变量。当页面重新加载时，检查会话变量是否设置。
If set use that $language
如果设置使用那个 $language
NOTE:
笔记：
$language = $_GET['language'];

You can't change a variable within PHP by html. PHP is serversided HTML is clientsided
您不能通过 html 更改 PHP 中的变量。PHP 是服务器端 HTML 是客户端
You can use GET variablesto change it though. It is the easiest way to do it.
不过，您可以使用GET 变量来更改它。这是最简单的方法。
