我有一个包含几张工作表的Excel文件。如何拆分此文件以获取每个工作表作为单独的文件？
从PHP开始，你需要像phpExcel这样的东西来打开电子表格，并将每个选项卡重写为一个新文件。
使用 PHPExcel 库：
include 'PHPExcel.php';
$fileType = 'Excel2007';
$inputFileName = 'testExcel.xlsx';
$objPHPExcelReader = PHPExcel_IOFactory::createReader($fileType);
$objPHPExcel = $objPHPExcelReader->load($inputFileName);
$sheetIndex = 0;
$sheetCount = $objPHPExcel->getSheetCount();
while ($sheetIndex < $sheetCount) {
++$sheetIndex;
$workSheet = $objPHPExcel->getSheet(0);
$newObjPHPExcel = new PHPExcel();
$newObjPHPExcel->removeSheetByIndex(0);
$newObjPHPExcel->addExternalSheet($workSheet);
$objPHPExcelWriter = PHPExcel_IOFactory::createWriter($newObjPHPExcel,$fileType);
$outputFileTemp = explode('.',$inputFileName);
$outputFileName = $outputFileTemp[0].$sheetIndex.'.'.$outputFileTemp[1];
$objPHPExcelWriter->save($outputFileName);
}
