大文件数据分割读取

$excelCutModel = new \excelUpload\ExcelCutRead($localFilePath, [ 'startRow' => '',//文件数据开始行 'averageNum' => 5000,//分割每页需要的数据 'invertedSubtract' => '',//尾部不需要数据的行数 'isReverse' => '',//文件数据读取是否倒序 ]); //分批获取以及处理需要的数据 $excelCutModel->cutFromFile(function ($excelData) { //处理$excelData });

将大文件分割成小文件

$file = '/tmp/a.xlsx'; $datas = [ '工作表_1' => [ [1, 'a'], [2, 'b'], [3, 'c'], [4, 'd'], ], '工作表_2' => [ [10, 'ab'], [20, 'bc'], [30, 'cd'], ], ]; $spreadsheet = new \PhpOffice\PhpSpreadsheet\Spreadsheet(); $i = 0; foreach ($datas as $sheetName => $sheetData) { if ($i > 0) { $spreadsheet->createSheet(); $spreadsheet->setActiveSheetIndex($i); } $spreadsheet->getActiveSheet()->setTitle($sheetName); foreach ($sheetData as $rowIndex => $row) { foreach ($row as $colIndex => $col) { $spreadsheet->getActiveSheet()->setCellValueByColumnAndRow($colIndex + 1, $rowIndex + 1, $col); } } $i++; } $writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xlsx'); $writer->save($file);

$excel = new \excelUpload\ExcelCutWrite(); $excel->cutNum = 4; $excel->returnType = 'Csv'; $result = $excel->cutFromFile($file);

$this->assertEquals(basename($result[0]), 'a_工作表_1_0.Csv'); $this->assertEquals(basename($result[1]), 'a_工作表_1_1.Csv'); $this->assertEquals(basename($result[2]), 'a_工作表_2_0.Csv'); $this->assertEquals(basename($result[3]), 'a_工作表_2_1.Csv');
