Specifying Which Argument in a Formatted String

What if you need to repeat one of the arguments within the formatted string? You could repeat the argument in the list again like this:

$message = sprintf( 'Welcome %s, your user id is %s. Hey, %s, ',
	$current_user['name']['first_name'],
	$user_id,
	$current_user['name']['first_name']
);

But then that’s a WET pattern, as you are repeating code.

Instead, PHP lets you specify which argument you want for each of the placeholders.
