PHP Paypal IPN Get transcation array
===

How do I get transaction array within $_POST array? 

Response: 

    cmd=_notify-validate&transaction=Array

Thats the response I get from my ipn ( minus all the other good stuff after transaction array )

I need to get the transaction amount, currency, and receiver which is.

    transaction[n].receiver
    transaction[n].amount
    transaction[n].currency

do I do `$_POST['transaction']['amount']`?
