How can the use of tools like PO Edit help in the translation process, and what are the best practices for integrating these translations into PHP code?

Using tools like PO Edit can help streamline the translation process by providing a user-friendly interface for managing translation files. To integrate these translations into PHP code, the gettext extension can be utilized to load the translated strings from the .po files and display them in the appropriate language on the website.

// Load the gettext extension
bindtextdomain('messages', 'path/to/translations');
textdomain('messages');

// Display a translated string
echo _("Hello, World!");
