What are some common mistakes that beginners make when trying to implement language selection scripts in PHP?

One common mistake beginners make when implementing language selection scripts in PHP is not properly setting up language files or directories. To solve this, ensure that you have separate language files for each language and organize them in a directory structure that makes sense. 

// Example of organizing language files in separate directories
$langDir = 'languages/';
$selectedLanguage = 'en';

require_once $langDir . $selectedLanguage . '.php';
```

Another mistake is not properly handling language switching based on user input. To fix this, make sure to sanitize and validate user input before switching languages.

```php
// Example of sanitizing and validating user input for language selection
$selectedLanguage = isset($_GET['lang']) ? $_GET['lang'] : 'en';
$allowedLanguages = ['en', 'fr', 'es']; // List of allowed languages

if (!in_array($selectedLanguage, $allowedLanguages)) {
    $selectedLanguage = 'en'; // Set default language if user input is not valid
}

require_once $langDir . $selectedLanguage . '.php';
