Add object to php array in symfony

Question

I currently have 2 classes: workerListClass workerClass The workerListClass gets a list of work with ids from database. For each of these the workerClass is called foreach ($query as $value) { $result = $this->worker->getWorkerById($value['ID']); // DB Call to get additional data $this->addData($result); vardumper::dump($result->getId()); // This results in 1031 and 1528 } addDate is very simple public function addData(workerClass $worker): void { $this->data[] = $worker; } But if i try to go through this array something strange happens $result = $this->workerListClass->getWorker()->getData(); foreach ($result as $worker) { vardumper::dump([ $worker->getId() // this outputs 1528 twice!!! ]); } getData does nothing special public function getData(): array { return $this->data; } Can someone help me why this outputs 1528 twice?

Answer 1

Problem found. The issues was that the same class was changed and not a new class was setup. Using clone on the workerlist helped fixing this: foreach ($query as $value) { $localWorker = clone $this->worker; //starts a new instance so that it is not referenced $result = $localWorker->getWorkerById($value['ID']); $this->addData($result); vardumper::dump($result->getId()); }
