i want to create a function to replace the space into dash then i found a solution for that

**this is the sulotion i found:**

```
function slug($phrase, $maxLength=100000000000000)
    {
        $result = strtolower($phrase);

        $result = preg_replace("/[^A-Za-z0-9\s-._\/]/", "", $result);
        $result = trim(preg_replace("/[\s-]+/", " ", $result));
        $result = trim(substr($result, 0, $maxLength));
        $result = preg_replace("/\s/", "-", $result);

        return $result;
    }

```

my problem is i want to create a vice versa for that replace dash to space

**example input:**

dash-to-space

**example output**
