oh i'm using v1.5.0 sdk , php 5.6.1
found root cause.
you forgot pass $apicontext object execute call in pay.php code.
try { $result = $payment->execute($execute); } catch(exception $e) { die($e); } change this, , should work:
try { $result = $payment->execute($execute, $apicontext); } catch(exception $e){ die($e); }
