Data::Dumper is your friend.
use Data::Dumper;
my %hash = ('abc' => 123, 'def' => [4,5,6]);

Parse query string into an array
...alone is note accurate, it could display for example:
$url = "somepage?id=123&lang=gr&size=300";
parse_str() would return:
Array (
[somepage?id] => 123
[lang] => gr
[size] => 300
)
It would be better to combine parse_str() with parse_url() like so:
$url = "som...
