PHPexcel将9 xlsx合并为一个

Question

我有以下脚本。

我想结合9（10000行/ xlsx）xlsx到一个。

我发现这个脚本并运行一个时间的前三个，然后其他时间，第4位，但不延长到9

现在有加setREadDataOnly但是，这并不工作。 还有另一种合并方式，或者我错过了一些设置吗？

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

不要打开并保存的目标文件（“big.xlsx”）循环的每次迭代里面......循环前一次打开它，只是把它保存在循环的最后一次迭代之后具有完成....这将更快，节省内存：

并确保您刷新较小的单个文件，否则垃圾收集不会从内存

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'); 

完全清理它们但如果它是只运行循环的3次或4次迭代而不是9次，检查它为什么失败日志，打内存限制或超时是最可能出现的问题

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