PHP Linux脚本操作实践：处理Excel文件

composer require phpoffice/phpexcel

require 'vendor/autoload.php';

// 打开Excel文件
$inputFile = 'path/to/excel/file.xlsx';
$reader = PhpOfficePhpSpreadsheetioFactory::createReader('Xlsx');
$spreadsheet = $reader->load($inputFile);

// 选择活动工作表
$worksheet = $spreadsheet->getActiveSheet();

// 获取表格的行数和列数
$rowCount = $worksheet->getHighestRow();
$columnCount = $worksheet->getHighestColumn();

// 读取表格中的数据
$data = [];
for ($row = 1; $row <= $rowCount; $row++) {
    $rowData = [];
    for ($col = 'A'; $col <= $columnCount; $col++) {
        $stringValue = $worksheet->getCell($col . $row)->getValue();
        $rowData[] = $stringValue;
    }
    $data[] = $rowData;
}

// 打印数据
foreach ($data as $rowData) {
    foreach ($rowData as $cellValue) {
        echo $cellValue . "    ";
    }
    echo PHP_EOL;
}

require 'vendor/autoload.php';

// 打开Excel文件
$inputFile = 'path/to/excel/file.xlsx';
$reader = PhpOfficePhpSpreadsheetIOFactory::createReader('Xlsx');
$spreadsheet = $reader->load($inputFile);

// 选择活动工作表
$worksheet = $spreadsheet->getActiveSheet();

// 修改表格中的数据
$worksheet->setCellValue('A1', 'New Value');
$worksheet->setCellValue('B1', 'New Value');

// 保存修改后的Excel文件
$outputFile = 'path/to/output/excel/file.xlsx';
$writer = PhpOfficePhpSpreadsheetIOFactory::createWriter($spreadsheet, 'Xlsx');
$writer->save($outputFile);

require 'vendor/autoload.php';

// 创建Excel对象
$spreadsheet = new PhpOfficePhpSpreadsheetSpreadsheet();
$worksheet = $spreadsheet->getActiveSheet();

// 写入数据
$worksheet->setCellValue('A1', 'Value 1');
$worksheet->setCellValue('B1', 'Value 2');

// 保存Excel文件
$outputFile = 'path/to/output/excel/file.xlsx';
$writer = PhpOfficePhpSpreadsheetIOFactory::createWriter($spreadsheet, 'Xlsx');
$writer->save($outputFile);
