What are some best practices for integrating PHP code into a Typo3 website for multilingual purposes?

To integrate PHP code into a Typo3 website for multilingual purposes, it is recommended to use TypoScript for language handling and localization. By using TypoScript conditions based on the current language, you can ensure that the correct content is displayed for each language on your website.

<?php
// Check the current language
$currentLanguage = $GLOBALS['TSFE']->sys_language_uid;

// Display different content based on the language
if($currentLanguage == 0) {
    // English content
    echo "Welcome to our website!";
} elseif($currentLanguage == 1) {
    // French content
    echo "Bienvenue sur notre site web!";
} elseif($currentLanguage == 2) {
    // German content
    echo "Willkommen auf unserer Webseite!";
}
?>
