I have this long foreach code I want to use to get folders and subfolders ids in order to be able to delete them.

// first foreach code       

$idsToDelete = $this->entityManager->getRepository(Folders::class)

            ->findBy(['parentId'=>$postId]);

foreach ($idsToDelete as $d){

    $postId = $d->getId(); echo $postId.', ';

    

    //second foreach code in first foreach

    $idsToDelete = $this->entityManager->getRepository(Folders::class)

                    ->findBy(['parentId'=>$postId]);

    foreach ($idsToDelete as $d){

        $postId = $d->getId(); echo $postId.', ';

        

        //third foreach code in second foreach

        $idsToDelete = $this->entityManager->getRepository(Folders::class)

                    ->findBy(['parentId'=>$postId]);

        foreach ($idsToDelete as $d){

            $postId = $d->getId(); 

            echo $postId.', ';

            

            //forth foreach code in third foreach

            $idsToDelete = $this->entityManager->getRepository(Folders::class)

                    ->findBy(['parentId'=>$postId]);

            foreach ($idsToDelete as $d){

                $postId = $d->getId(); echo $postId.', ';

            

                //fith foreach code in forth foreach

                $idsToDelete = $this->entityManager->getRepository(Folders::class)

                        ->findBy(['parentId'=>$postId]);

                foreach ($idsToDelete as $d){

                    $postId = $d->getId(); echo $postId.', ';

                }

            }

        }

    }

}

the problem with this code is that, I will have to write foreach statement for each iteration I want to make.
How do I write a simple loop or function to do this once.
Thanks.

My Answer:
>getIdsToDelete($folders);

foreach ($idsToDelete as $id) {
// second foreach code
$subfolders = $this->getSubfolders($id);

foreach ($subfolders as $subfolder) {
// delete subfolder
$this->deleteSubfolder($subfolder);
}

// delete folder
$this->deleteFolder($id);
}

In this code snippet, the first foreach loop is used to get the ids of folders that need to be deleted. Then, for each folder id, a second foreach loop is used to get the subfolders of that folder and delete them. Finally, the folder itself is deleted.
