PhpSpreadsheet - 多张纸上的块数据

Question

我需要读取一张10张的xlsx文件，每张约有3K行。

有没有办法循环每张纸并将其排成一排？

按照这些例子我就这一点：

public function import($file)
{
    $inputFileType = IOFactory::identify($file);
    $reader = IOFactory::createReader($inputFileType);

    //My ChunkReadFilter is exactly the same of the PhpSpreadsheet examples
    $chunkFilter = new ChunkReadFilter();
    $reader->setReadFilter($chunkFilter);

    $chunkSize = 100;

    $spreadsheet = $reader->load($file);

    $loadedSheetNames = $spreadsheet->getSheetNames();

    foreach ($loadedSheetNames as $sheetIndex => $loadedSheetName) {
        $sheet = $spreadsheet->getSheet($sheetIndex);

        //$highestRow = $sheet->getHighestRow(); //Is returning 1 as result
        $highestRow = 3000;

        for ($startRow = 1; $startRow <= $highestRow; $startRow += $chunkSize) {
            /**  Tell the Read Filter which rows we want this iteration  **/
            $chunkFilter->setRows($startRow, $chunkSize);

            $sheetData = $sheet->toArray(null, true, false, true);
            var_dump($sheetData);
        }

    }
}

var_dump($sheetData);打印所有工作表数据，而不仅仅是块大小。

那么，我如何读取每个工作表数据并将行分块？

我完全错过了你的目标（问题不是那么清楚）。我完全改变了我的答案。假设您可以使用以下代码循环遍历多个工作表：

// .... add helper here....
$helper->log('Loading file ' . pathinfo($inputFileName, PATHINFO_BASENAME) . ' using IOFactory with a defined reader type of ' . $inputFileType);
$reader = IOFactory::createReader($inputFileType);

// Define how many rows we want for each "chunk"
$chunkSize = 10;

// Loop to read our worksheet in "chunk size" blocks
for ($startRow = 2; $startRow <= 50 ; $startRow += $chunkSize) {
    // ..... use the helper ...
    $helper->log('Loading WorkSheet using configurable filter for headings row 1 and for rows ' . $startRow . ' to ' . ($startRow + $chunkSize - 1));
    // Create a new Instance of our Read Filter, passing in the limits on which rows we want to read
    $chunkFilter = new ChunkReadFilter($startRow, $chunkSize);
    // Tell the Reader that we want to use the new Read Filter that we've just Instantiated
    $reader->setReadFilter($chunkFilter);
    // Load only the rows that match our filter from $inputFileName to a PhpSpreadsheet Object
    $spreadsheet = $reader->load($inputFileName);

    $sheetCount = $spreadsheet->getSheetCount();

    for ($i = 0; $i < $sheetCount; $i++) {
        $sheet = $spreadsheet->getSheet($i);

        // ...not what you want, but I leave this here
        $higestRow = $sheet->getHighestRow();
        echo "<p> Sheet n. ".$i. "  highest row is:" . ($higestRow) . "</p>";

        $sheetData = $sheet->toArray(null, true, true, true);

        var_dump($sheetData);
    }
}

...为了达到你的目标，我猜你需要调用use PhpOffice\PhpSpreadsheet\Reader\IReadFilter;并构建自己的过滤器，以便在for循环中设置highestRow，以满足您的需求。这段代码取自文档，poblic函数setRows()我想你需要放置自己的代码，而不是cal在for循环中的过滤器：

namespace Samples\Sample12;

use PhpOffice\PhpSpreadsheet\IOFactory;
use PhpOffice\PhpSpreadsheet\Reader\IReadFilter;

require __DIR__ . '/../Header.php';

$inputFileType = 'Xls';
$inputFileName = __DIR__ . '/sampleData/example2.xls';

/**  Define a Read Filter class implementing IReadFilter  */
class ChunkReadFilter implements IReadFilter
{
    private $startRow = 0;

    private $endRow = 0;

/**
 * Set the list of rows that we want to read.
 *
 * @param mixed $startRow
 * @param mixed $chunkSize
 */
public function setRows($startRow, $chunkSize)
{
    $this->startRow = $startRow;
    $this->endRow = $startRow + $chunkSize;
}

public function readCell($column, $row, $worksheetName = '')
{
    //  Only read the heading row, and the rows that are configured in            $this->_startRow and $this->_endRow
    if (($row == 1) || ($row >= $this->startRow && $row <   $this->endRow)) {
        return true;
    }

    return false;
    }
}

$helper->log('Loading file ' . pathinfo($inputFileName, PATHINFO_BASENAME) . ' using IOFactory with a defined reader type of ' . $inputFileType);
// Create a new Reader of the type defined in $inputFileType
$reader = IOFactory::createReader($inputFileType);

// Define how many rows we want to read for each "chunk"
$chunkSize = 10;
// Create a new Instance of our Read Filter
$chunkFilter = new ChunkReadFilter();

// Tell the Reader that we want to use the Read Filter that we've  Instantiated
$reader->setReadFilter($chunkFilter);

$spreadsheet = $reader->load($inputFileName);

$sheetCount = $spreadsheet->getSheetCount();

for ($i = 0; $i < $sheetCount; $i++) {
    $sheet = $spreadsheet->getSheet($i);
    // ...we get the highest row here, now
    $higestRow = $sheet->getHighestRow();

    for ($startRow = 2; $startRow <= $higestRow; $startRow += $chunkSize) {
        // ..just for check the output
        echo "<p> Sheet n. ".$i. "  highest row is:" . ($higestRow) . "</p>";
        $helper->log('Loading WorkSheet using configurable filter for headings row 1 and for rows ' . $startRow . ' to ' . ($higestRow + $chunkSize - 1));
        // Tell the Read Filter, the limits on which rows we want to read this iteration
        $chunkFilter->setRows($startRow, $chunkSize);
        // Load only the rows that match our filter from $inputFileName to a PhpSpreadsheet Object
        $spreadsheet = $reader->load($inputFileName);

        // Do some processing here

        $sheetData = $spreadsheet->getActiveSheet()->toArray(null, true, true, true);
        var_dump($sheetData);
    }

}
