Can you tell us what you want in PHP syntax? Because first you are using '--', then you're using ',', and I don't know what each of them represent...
Do you mean like, you have:
$arr['mydomain.com'] = 11.99;
$arr['mydomain.co.uk'] = 5.99;
and you want to end up with:
$arr['mydomain.com'] = 11.99;
$arr['mydomain.co.uk'] = 5.99;
$arr2[0] = 11.99;
$arr2[1] = 5.99;
? That's what I mean by explaining the problem with PHP syntax 🙂
