#39435 [Asn->Csd]: wrong instanceof results

ID: 39435 Updated by: pollita@php.net Reported By: mp at webfactory dot de -Status: Assigned +Status: Closed Bug Type: Class/Object related Operating System: any PHP Version: 5.2.0 Assigned To: pollita New Comment: This bug has been fixed in CVS. Snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. Thank you for the report, and for helping us make PHP better. This has been changed to throw a proper error message rather than the uninformative one given. Perhaps in future versions this can be changed to allow constant strings giving the expected output, but not currently.
