Edit report at https://bugs.php.net/bug.php?id=54991&edit=1 ID: 54991 Updated by: beberlei@php.net Reported by: giorgio dot liscio at email dot it Summary: domimplementation instance is not a reference inside domdocument -Status: Analyzed +Status: Wont fix Type: Bug Package: DOM XML related Operating System: any? PHP Version: 5.3.6 -Assigned To: +Assigned To: beberlei Block user comment: N Private report: N New Comment: ext/dom doesn't guarantee reference equality, new instances are often created from properties that behave more like "magic" __get returning new instances based on underlying data. For this case though, PHP DOMImplementation doesn't support any other implementation than the one in code. Also don't trust hasFeature on it, because that data is just hardcoded.
