您好我用PHPExcel生成xls文件并且它运行良好（即使使用6000行文件）但是当我尝试使用9000行时（我没有尝试使用8000）它会使Excel无法读取文件。
这是我的代码：
public function generationExcelAction(Request $request)
{
/*
* set_time_limit & ini_set on été ajouté afin d'éviter le timeout lors d'un export excel trop volumineux.
*/
set_time_limit (0);
ini_set('memory_limit', '-1');
$this->getDoctrine()->getConnection()->getConfiguration()->setSQLLogger(null);
/** @var \Nalods\Entity\ArticleRepository $repoArticles */
$repoArticles = $this->getDoctrine()->getRepository('Nalods\Entity\Article');
$requeteArticle = $repoArticles->findByPlateforme($this->getUser()->getPlateforme()->getId());
$filter = new ReassortFilter();
$filterForm = $this->createForm(
ReassortFilterType::class,
$filter,
[
'arbo' => $this->getArborescenceManager()->getArborescenceForReassort(),
'fournisseurs' => $this->getDoctrine()->getRepository('Nalods\Entity\FournisseurCommun')->getFournisseursForReassort($this->getUser()->getPlateforme()->getId()),
]
);
$filterForm->handleRequest($request);
$requeteArticle = $repoArticles->applyFilters($requeteArticle, $filter, $request->getSession()->get(Commande::ID_SESSION));
$requeteArticle->select('DISTINCT a.id');
$listeIdArticles = $requeteArticle->getQuery()->getScalarResult();
$response = new StreamedResponse();
$response->setCallback(function () use ($listeIdArticles) {

如果有人能为我提供完美的东西，我怎么能提高我的代码，使它能够运行更多的线条呢？
度过美好的一天！
