No, the PHP code looks fine to me.

I can make this work by adding this ctor to ptr.i:

    shared_ptr(const shared_ptr &);

The C++ compiler should implicitly create such a copy constructor in
this situation, so I don't know why SWIG isn't doing so, but at least
the workaround is easy.  Perhaps the PHP5 wrappers don't include methods
which the compiler automatically synthesises, but I don't have time
to investigate at present.

Patches to improve the generated PHP code welcome!

Part of the problem is that the PHP5 classes wrap the flat function
interface to C++ classes which SWIG already produced for PHP4 with
"-noproxy".  I resisted changing the flat function interface stuff more
than I had to so as to minimise the risk of breaking PHP4 support.

Once PHP4 support becomes irrelevant (probably less than a year from
now) this could probably be improved.
