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

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…

Answer

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 )
