What are the potential drawbacks of incorporating language selection logic in multiple places within a PHP script?

Potential drawbacks of incorporating language selection logic in multiple places within a PHP script include code duplication, maintenance difficulties, and increased chances of introducing errors or inconsistencies. To solve this issue, it is recommended to centralize language selection logic in a separate file or function and call this function whenever language selection is needed in the script. 

// Centralize language selection logic in a separate function

function getTranslatedText($key, $lang) {
    $translations = [
        'hello' => [
            'en' => 'Hello',
            'fr' => 'Bonjour',
            'es' => 'Hola'
        ],
        // Add more translations as needed
    ];

    return $translations[$key][$lang] ?? $key;
}

// Example usage
$lang = 'en';
echo getTranslatedText('hello', $lang);
