有没有什么办法可以加快我的功能来处理更大的excel文件？ 有我的代码：如何使用symfony2 phpexcel bundle缓存phpexcel
$excelService = $this->get('xls.service_xls5');
$excelObj = $this->get('xls.load_xls5')->setReadDataOnly(true)->load('../web/bundles/static/pliki/'.$name);
$sheet = $excelObj->getSheet(0);
$highestRow = $sheet->getHighestRow();
$highestColumn = $sheet->getHighestColumn();
for ($row = 1; $row <= $highestRow; $row++){
$nazwaKlienta = $sheet->getCellByColumnAndRow(0,$row)->getValue();
$ulica = $sheet->getCellByColumnAndRow(1,$row)->getValue();
$miasto = $sheet->getCellByColumnAndRow(2,$row)->getValue();
$kod = $sheet->getCellByColumnAndRow(3,$row)->getValue();
$notatka = $sheet->getCellByColumnAndRow(4,$row)->getValue();
$kolor = $sheet->getCellByColumnAndRow(5,$row)->getValue();
if ($row == $highestRow) {
$excelObj->disconnectWorksheets();
unset($excelObj);
}
$em = $this->getDoctrine()->getManager();
$klient = new Klient();
$klient->setNazwa($nazwaKlienta);
(...)
$em->persist($klient);
$em->flush();
$klientId = $klient->getId();
$punkt = new Punkty();
$punkt->setIdKlienta($klient);
$em->persist($punkt);
$em->flush();
}
此代码开放现有的Excel文件和读取的所有数据，并将其写入到数据库中。它适用于大约150-200的数据量，但我需要处理大约2000行的数据。我如何使用phpexcelBundle进行缓存或者有其他方法？
