The PHP API does not modify the returned documents, so if you send a normal X-Query via the query-method, you will get a result including the ino:id attributes - if however you send a Plain-URL-Addressing request via the plainUrlAddressing-method or an XQuery request via the xquery-method, then the resulting XML document will not include the ino:id attributes.
