How does gettext work with dynamic content in PHP?

When working with dynamic content in PHP, gettext can still be used to translate the strings. To do this, the dynamic content should be wrapped in gettext functions so that it can be translated based on the current locale. This involves using the gettext function to retrieve the translated string for the dynamic content.

<?php
// Set the locale
$locale = 'en_US';
putenv("LC_ALL=$locale");
setlocale(LC_ALL, $locale);

// Specify the location of the translation files
bindtextdomain('messages', 'path/to/translations');
textdomain('messages');

// Gettext function to translate dynamic content
echo _('Hello, World!'); // Dynamic content to be translated
?>
