New: Uri pathSegments() helper method

[chester-sykes]

Recently I ran into a situation where I needed the first path segment from an url, so I have added pathSegments() helper method to the Uri class to easily access them.

Calling pathSegments() on the Uri class will return an colleciton of all path segments then you can easily access any of them.

So instead of doing something like this:

        $path = Uri::of('https://laravel.com/one/two/three')->path();
        
        $firstSegment = collect(explode('/', $path))->first();
        // result: 'one'

You could just do this:

        $firstSegment = Uri::of('https://laravel.com/one/two/three')->pathSegments()->first();
        // result: 'one'

I think that this would be a handy to have if you are dealing with path segments. It doesn't break any existing features as it's a new method.

I wonder if (not necessarily in this PR though) path() should return a custom collection (or Arrayable/ArrayAccess or the like) similar to UriQueryString that would

• __toString() by internally calling implode() with / as glue
• allowing to access and modify path segments by numeric index as well as name, in case we allow uri templates with Uri
• etc.
