Replacing string with some variable

Question

I am not an expert with Regular Expression, so maybe this question has some basic implementation of regex.

First I have retrieve some string from user which has a format like this:

$id =3;
$format = {num}/sometext/sometext;

The question is how to replace {num} with the variable of id, so the result will be :

3/sometext/sometext;

it's kind of like a templating engine.

Couldn't you just use str_replace('{num}', $id, $format); ?
