php - 使用 PHPExcel 循环工作表

Question

我正在使用 PHPExcel 库来读取 Excel 文件并对其进行处理。我想遍历每个工作表。我检查了文档，我能找到的只是更改事件工作表索引或仅加载指定的工作表。如何循环遍历所有工作表？

感谢您的帮助。

这是文档的循环示例，供引用:

<?php
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
$objReader->setReadDataOnly(true);

$objPHPExcel = $objReader->load("test.xlsx");
$objWorksheet = $objPHPExcel->getActiveSheet();

echo '<table>' . "\n";
foreach ($objWorksheet->getRowIterator() as $row) {
  echo '<tr>' . "\n";

  $cellIterator = $row->getCellIterator();
  $cellIterator->setIterateOnlyExistingCells(false); // This loops all cells,
                                                     // even if it is not set.
                                                     // By default, only cells
                                                     // that are set will be
                                                     // iterated.
  foreach ($cellIterator as $cell) {
    echo '<td>' . $cell->getValue() . '</td>' . "\n";
  }

  echo '</tr>' . "\n";
}
echo '</table>' . "\n";
?>

我认为你可以做到这一点。增加事件工作表直到没有剩余，然后对每个工作表执行您想要的操作:

<?php

    $objReader = PHPExcel_IOFactory::createReader('Excel2007');
    $objReader->setReadDataOnly(true);

    $objPHPExcel = $objReader->load("test.xlsx");

    $i = 0;
    while ($objPHPExcel->setActiveSheetIndex($i)){

        $objWorksheet = $objPHPExcel->getActiveSheet();
        //now do whatever you want with the active sheet
        ...
        $i++;

    }

    ...
