Proponowałbym jednak aż tak nie modyfikować kodu w szczególności początku gdzie szczytuje się dane z posta które są bardzo podatne na serializacje. Nie dodawaj do $req żadnych dodatkowych znaków gdyż dane wysłane do PayPal muszą być identyczne do tych które otrzymasz poddane urlencode.
Proponuje zostawić kod w niezmienionej formie i przetestować go najpierw z symulatorem:
