What are some best practices for organizing and accessing variables stored in PHP include files for text translations or other purposes?

When organizing variables in PHP include files for text translations or other purposes, it is best practice to use associative arrays to store the variables. This allows for easy access and management of the variables within the file. Additionally, using a separate include file specifically for storing these variables can help keep your code organized and maintainable.

// translation.php

$translations = array(
    'hello' => 'Hello',
    'goodbye' => 'Goodbye',
    'welcome' => 'Welcome',
);

// To access a translation:
echo $translations['hello'];
