What are some potential pitfalls to be aware of when using constants in PHP for language translation?

One potential pitfall when using constants for language translation in PHP is that they are not easily dynamic and may not be suitable for handling variables or placeholders in translated strings. To solve this issue, you can use a combination of constants and sprintf function to handle placeholders in translated strings. 

// Define language constants
define('GREETING', 'Hello, %s!');

// Placeholder value
$name = 'John';

// Translate and format the string
$translatedGreeting = sprintf(constant('GREETING'), $name);

echo $translatedGreeting;
