regex

I've seen so many misuses of RegExp, I don't really like it :)

I have string (as a result of two str_replaces) that might look something like this:

.?This iš my ".stRiNg."!
          |
          V
--this-is-my---string---

Is there any way better than

$string = trim(preg_replace('/[-]+/u','-', $string),'-');

to get:

this-is-my-string

?
