Building Multilingual Websites with PHP: Eliminating Language Barriers

php Xiaobian Banana teaches you how to build a multilingual website with PHP, allowing you to easily eliminate language barriers. With simple settings and techniques, you can add multiple language options to your website to provide a more friendly access experience for users in different regions. Make your website more attractive and international!

Create a new table for multilingual data, including the following fields:

CREATE TABLE translations (
id INT NOT NULL AUTO_INCREMENT,
locale VARCHAR(255) NOT NULL,
key VARCHAR(255) NOT NULL,
value TEXT NOT NULL,
PRIMARY KEY (id)
);

2. Set language switching mechanism

Add a language switcher to the top or sidebar of your website to allow users to select their preferred language.

// 获取当前语言
$current_locale = isset($_GET["locale"]) ? $_GET["locale"] : "en";

// 语言链接
$languages = array("en", "es", "fr");
foreach ($languages as $lang) {
echo "<a href="?locale=$lang">$lang</a> ";
}

3. Load translation

Load translations for the current language from the database.

// 查询翻译
$translations = $db->prepare("SELECT * FROM translations WHERE locale = ?");
$translations->execute(array($current_locale));

// 存储翻译数组
$tr = array();
foreach ($translations as $row) {
$tr[$row["key"]] = $row["value"];
}

4. Show translation

In your html code, use the gettext function to get the text from the translation array.

// 使用 gettext 获取翻译
echo gettext("This is a test");

5. International date and time

For date and time display, use PHP’s Intl extension:

// 创建 DateTime 对象
$dt = new DateTime();

// 国际化日期和时间格式
$dt->setTimezone(new DateTimeZone("Europe/London"));
echo $dt->fORMat("Y-m-d H:i:s");

6. Localized numbers and currencies

Likewise, for number and currency formatting, use the Intl extension:

// 创建 NumberFormatter 对象
$formatter = new NumberFormatter("en_US", NumberFormatter::CURRENCY);

// 格式化货币
$amount = 1000;
echo $formatter->formatCurrency($amount, "USD");

7. Keep the code clean

To keep your code clean, you can create functions and helpers to simplify the process of translation and internationalization. For example:

function t($key) {
global $tr;
return isset($tr[$key]) ? $tr[$key] : $key;
}
