PHPexcel将9个xlsx合并为一个

Question

我有以下脚本。

我想将 9 个（每个 xlsx 10000 行）xlsx 合并为一个。

我找到了这个脚本，前三个运行一次，前四个运行一次，但没有扩展到 9。

现在添加了 setREadDataOnly 但这也不起作用。 还有其他方法可以合并还是我错过了一些设置？

脚本： require_once 'PHPExcel.php'; require_once 'PHPExcel/Writer/Excel2007.php'; require_once 'PHPExcel/IOFactory.php';

    $objReader = PHPExcel_IOFactory::createReaderForFile("big.xlsx");
    $objReader->setReadDataOnly(true);
    $objPHPExcel1 = $objReader->load("big.xlsx");

for( $x=1; $x <= 9;$x++  ){

    $objReader2 = PHPExcel_IOFactory::createReaderForFile("000$x.xlsx");
    $objReader2->setReadDataOnly(true);
    $objPHPExcel2 = $objReader2->load("000$x.xlsx");

    $findEndDataRow2        = $objPHPExcel2->getActiveSheet()->getHighestRow();
    $findEndDataColumn2     = $objPHPExcel2->getActiveSheet()->getHighestColumn();
    $findEndData2 = $findEndDataColumn2 . $findEndDataRow2;

    $data2 = $objPHPExcel2->getActiveSheet()->rangeToArray('A2:' . $findEndData2);

    $appendStartRow = $objPHPExcel1->getActiveSheet()->getHighestRow() + 1;
    $objPHPExcel1->getActiveSheet()->fromArray($data2, null, 'A' . $appendStartRow);

}

    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel1, 'Excel2007');
    $objWriter->save('big.xlsx');

不要在循环的每次迭代中打开并保存您的目标文件（“big.xlsx”）...在循环之前打开一次，并且仅在循环的最后一次迭代完成后保存它。 ..这样会更快并节省内存：

并确保刷新较小的单个文件，否则垃圾收集不会完全从内存中清除它们

require_once 'PHPExcel.php';
require_once 'PHPExcel/Writer/Excel2007.php';
require_once 'PHPExcel/IOFactory.php';

$objReader = PHPExcel_IOFactory::createReaderForFile("big.xlsx");
$objReader->setReadDataOnly(true);
$objPHPExcel1 = $objReader->load("big.xlsx");

$appendStartRow = $objPHPExcel1->getActiveSheet()->getHighestRow() + 1;

for( $x=1; $x <= 9;$x++  ){

    $objReader2 = PHPExcel_IOFactory::createReaderForFile("000$x.xlsx");
    $objReader2->setReadDataOnly(true);
    $objPHPExcel2 = $objReader2->load("000$x.xlsx");

    $findEndDataRow2        = $objPHPExcel2->getActiveSheet()->getHighestRow();
    $findEndDataColumn2     = $objPHPExcel2->getActiveSheet()->getHighestColumn();
    $findEndData2 = $findEndDataColumn2 . $findEndDataRow2;

    $data2 = $objPHPExcel2->getActiveSheet()->rangeToArray('A2:' . $findEndData2);

    $objPHPExcel2->disconnectWorksheets();
    unset($objPHPExcel2);

    $objPHPExcel1->getActiveSheet()->fromArray($data2, null, 'A' . $appendStartRow);
    $appendStartRow += count($data2);

    unset($data2);
}

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel1, 'Excel2007');
$objWriter->save('big.xlsx');

但如果它只运行 3 或 4 次循环而不是 9 次，请检查它在日志中失败的原因，最有可能出现的问题是达到内存限制或超时

我的方法是使用循环并单独设置单元格值。我想我本可以使用@Mark Ba​​ker 答案的一部分，但这对我有用。请注意，所有文件都应具有相同数量的字段。
