What are the best practices for handling language selection and inclusion in PHP scripts?

To handle language selection and inclusion in PHP scripts, it is recommended to use language files or arrays to store translations for different languages. You can create a function to load the appropriate language file based on user selection or browser settings, and then use this function to retrieve the correct translation for each text in your script. 

```php
<?php

// Function to load language file based on user selection or browser settings
function loadLanguage($lang) {
    $langFile = "lang/" . $lang . ".php";
    if (file_exists($langFile)) {
        include $langFile;
    } else {
        // Default to English if language file not found
        include "lang/en.php";
    }
}

// Usage example
$lang = "en"; // Default language
if (isset($_GET['lang'])) {
    $lang = $_GET['lang']; // Change language based on user selection
}

loadLanguage($lang);

// Access translated text using language array
echo $lang['hello']; // Output: Hello
```

In this code snippet, we have a function `loadLanguage()` that includes the appropriate language file based on the user selection or defaulting to English if the file is not found. The translated text can then be accessed using the language array `$lang`.
