PhpSpreadsheet 安装及单元格操作

1.安装

composer require phpoffice/phpspreadsheet

2.读取xls文件

public function test(){$reader = \PhpOffice\PhpSpreadsheet\IOFactory::createReader('Xls');$reader->setReadDataOnly(TRUE);$spreadsheet = $reader->load("public/csv/2024.xls");$worksheet = $spreadsheet->getActiveSheet();echo '<table>' . PHP_EOL;foreach ($worksheet->getRowIterator() as $row) {echo '<tr>' . PHP_EOL;$cellIterator = $row->getCellIterator();$cellIterator->setIterateOnlyExistingCells(FALSE); //这在所有单元格中循环,//即使没有设置单元值。//对于“TRUE”，我们在单元格中循环//只有当它们的值被设置时。//如果不调用该方法，//默认值为“false”foreach ($cellIterator as $cell) {echo '<td>' .$cell->getValue() .'</td>' . PHP_EOL;}echo '</tr>' . PHP_EOL;}echo '</table>' . PHP_EOL;}

3.写入文件

require 'vendor/autoload.php';
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
$spreadsheet = new Spreadsheet();
$activeWorksheet = $spreadsheet->getActiveSheet();
$activeWorksheet->setCellValue('A1', 'Hello World !');#注A1  A表示列 1表示行
$writer = new Xlsx($spreadsheet);
$writer->save('hello world.xlsx');
