Reproduce code: --------------- http://dev.plauditdesign.com/~hjiverson/drop/php-soap-multiref-bug.txt Expected result: ---------------- The server should use mutliRefs and create references to each object. Each object instance would be serialized one time and given a unique ID, which is then pointed to each time an reference to that object is encountered. Something like this: <getThingWithParentResponse> <result href="#object1"/> </getThingWithParentResponse> ... <multiRef xsi:type="ThingWithParent" id="object1"> ... <parent xsi:nil="1"/> <children> <child href="#object2"/> </children> </multiRef> <multiRef xsi:type="ThingWithParent" id="object2"> ... <parent href="#object1"/> <children xsi:nil="1"/> </multiRef> Actual result: -------------- php hangs ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37013&edit=1
