How to replace a variable in a string using PHP?

Question

So I have PHP code that looks like this:

$message = 'Here is the result: %s';

I just used% s as an example. This is basically a placeholder for whatever. Then I pass the string to the function, and I want this function to replace% s with a value.

What do I need to do for this? Do I need to do some regular expression and use preg_replace () or something else? or is there an easier way to do this?
