Best way to pass and get multiple values for same parameter via URL in PHP

Question

I'm looking into what is the best way to pass multiple values for the same parameter name via URL in PHP and then get those results.

Example:

http://www.example.com?color=blue&color=red&color=green

For some reason all the answers I can find is for other programing languages...

You'd have to "pack", eg. like ?color=red,green,blue and then explode it on the server side explode(',', $_GET['color']) — Honk der Hase

What is the standard? Doing that "pack" or pass them as array like the Ashu example? — ramenknight

Ashus approach is better in my opinion, because it's cleaner and uses the standarized, official way. — Honk der Hase

You can pass them as an array

 http://www.example.com?color[]=blue&color[]=red&color[]=green

On server side use $_GET['color'], which should return an array

print_r($_GET['color']); // Array ( [0] => green [1] => red [2] => blue )

Sounds great, I think this solves my problem. Side question Is it also possible to make this type of url seo friendly like example.com/colors/blue/red/green via .htaccess?
