如何在PhpSpreadsheet中获取第一列索引

Question

我必须遍历 xls 文档前两列的所有行。问题是该特定文档的第一列是“G”，索引为 7。有没有办法获得第一列索引，因为我不想对其进行硬编码。我的循环：$spreadsheet =\PhpOffice\PhpSpreadsheet\IOFactory::load($path);$worksheet = $spreadsheet->getActiveSheet();$highestRow = $worksheet->getHighestRow();$rows = [];for ($row = 1; $row <= $highestRow; ++$row) {    // I WANT TO REPLACE HARD-CODED VALUES OF 7 AND 8    // WITH $firstCol and $firstCol+1    for ($col = 7; $col <= 8; ++$col) {         $value = $worksheet->getCellByColumnAndRow($col, $row)->getValue();        $rows[$row][$col] = $value;    }}

Answer 1

您可以添加一个while循环来跳过空单元格。试试这个：

$rows = [];

for ($row = 1; $row <= $highestRow; ++$row) {

    $col = 1;

    $cell = $worksheet->getCellByColumnAndRow($col, $row);

    // Skip empty cells

    while (in_array($cell->getValue(), [null, ''], true)) {

        $col++;

        $cell = $worksheet->getCellByColumnAndRow($col, $row);

    }

    $maxCol = $col + 1;

    for ( ; $col <= $maxCol; ++$col) { 

        $value = $worksheet->getCellByColumnAndRow($col, $row)->getValue();

        $rows[$row][$col] = $value;

    }

}
