			0 ignored issues – show Documentation Bug introduced 2016-08-23 14:21 UTC by Report Bug Copy Issue Report It seems like `fopen('php://temp', 'w+')` of type `resource` is incompatible with the declared type `null` of property `$debug_log_temp_stream_handle`. Our type inference engine has found an assignment to a property that is incompatible with the declared type of that property. Either this assignment is in error or the assigned type should be added to the documentation/type hint for that property.. Loading history...
