Q:

PHP: How do i write a $_GET/$_POST string to include a nested array?

I'm looking to manually write a multidimensional $_GET/$_POST query string, saw this done the other day but can't quite remember it!
something like:
www.url.com?val1=abc&val2=cde&[val3=fgh&val4=ijk]

A:

http://domain.tld/path/to/script.php?arr[a][b][c]=foo

and
var_dump($_GET);
