Issue description

You give wrong requirements.
Your script doesn't work in PHP 5.3 due to low version of OpenSSL in curl library in PHP 5.3, it doesn't work in PHP 5.4.10 too (the same reason).

More over. You have a mistake in:
PayPal-PHP-SDK/sample/billing/GetBillingAgreement.php

There is the following instruction:
$createdAgreement = "your billing agreement id";

But further you use a method of class:
$createdAgreement->getId();
