what is happening is that your Object Definition has a syntax error but php
is complaining about the json_encode.
I believe (from the php.net docs) that it should be

$myObj = new stdClass();
> $myObj->name = "John";

I highly recommend the php.net documentation.  It shows different ways to
do this and it looks like you merged two different styles that are
incompatible.
As a suggestion, in the future, assume it is a php problem and try Stack
Exchange first.  If everyone there says, "everything looks good, could be
your distro / OS", then post to the FreeBSD List and explain what steps you
have already taken.  It will help keep responses much more friendly.
