You can use place-holders and str_replace. Or use PHP's built-in sprintf and use %s. (And as of v4.0.6 you can swap the ordering of arguments if you'd like).

$name = 'Alica';

// sprintf method:
$format = 'Hello, %s!';
echo sprintf($format, $name); // Hello, Alica!

// replace method:
$format = "Hello, {NAME}!";
echo str_replace("{NAME}", $name, $format);
