代码内容结构中的多语言网站

Question

Trying to find the best way to make a multi language site. This is what i have done to this moment:

<?php
    if (isset($_GET['lang'])) {
        $lang = $_GET['lang'];
    }

    $content = array(
            'bg' => array(
                'word1' => 'Начало',
                'word2' => 'Тест'
            ),


            'en' => array(
                'word1' => 'Home',
                'word2' => 'Test'
            ),
        );
?>

And then print the content this way:

<?= $content[$lang]['word1'] ?>
<?= $content[$lang]['word2'] ?>

Here is picture of the code too. I'm doing this for first time so probably I'm doing something wrong. How can I improve this structure?
Also I'm doing transalte on everything that displays on the pages, not just the content so I think puting it in the data base is wrong.

Answer 1

The way you are doing it currently is totally fine, but I would recommend to you to seperate your translations from your code to keep the files clean.

Doing this, you could still use PHP for your translation files, but you don't have to declare the translations in every file (and maybe have them multiple times)

bg.php

<?php
return [
    'word1' => '...',
    'word2' => '...'
];
?>

and to include your translation, just write something like this

$content = require('translations/' . $lang . '.php');
echo $content['word1'];

Doing this, you should also check, that the given language is valid.

$valid_languages = ['bg', 'en'];
if (!in_array($lang, $valid_languages)) die('usefull message');
