What are the potential pitfalls of using variables in language files for multiple languages in PHP forms?

Using variables in language files for multiple languages in PHP forms can lead to potential pitfalls such as variable collisions and inconsistencies in translations. To avoid these issues, it is recommended to use an associative array to store language strings for each language, with keys representing the language and values representing the translations. 

// Define language strings in associative arrays
$english = array(
    'welcome_message' => 'Welcome to our website!',
    'submit_button' => 'Submit'
);

$spanish = array(
    'welcome_message' => '¡Bienvenido a nuestro sitio web!',
    'submit_button' => 'Enviar'
);

// Set default language
$language = $english;

// Access language strings using the chosen language
echo $language['welcome_message'];
echo $language['submit_button'];
