PHP is a much simpler language which helps a lot with optimizations. For instance, consider something like property access.
In PHP, doing `$a->b` accesses field `b` of object `$a`. The implementation is essentially type check (making sure `$a` is an object) and hash table lookup. If this fails, then it calls `__get` method if it exists.
In Python on the other hand, `a.b` involves `__getattr__`, `__getattribute__`, `__mro__`, `__get__`, `__set__`, `__delete__` and `__dict__`. Here is a description of how the attribute access works: https://docs.python.org/3/howto/descriptor.html#overview-of-....
