列从0开始算,行从1开始算 $sheet->setCellValueByColumnAndRow(0,1,‘特别说明‘);
composer require phpoffice/phpspreadsheet 版本号
默认情况会提示找不到库,上composer找是有的,是因为还没有稳定版,所以要指定版本 1.0.0beta
依赖
The following software is required to develop using PhpSpreadsheet:
默认使用ZipArchive来压缩保存
注意读写权限
require ‘vendor/autoload.php‘;
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();
$sheet->setCellValue(‘A1‘, ‘Hello World !‘);
$writer = new Xlsx($spreadsheet);
$writer->save(‘hello world.xlsx‘);
默认保存到执行php的根目录,以thinkphp为例index.php在D:\wwwroot\thinkphp\public
,那么文件就保存在这
注:如果不想保存到文件,可以传入php://output
或php://stdout
直接输出(例如html,输出网页)
全用代码写太累,可以用模板来修改,但是对于动态数据,还是要由代码生成
//通过工厂模式创建内容
$spreadsheet = \PhpOffice\PhpSpreadsheet\IOFactory::load(‘template.xlsx‘);
$worksheet = $spreadsheet->getActiveSheet();
$worksheet->getCell(‘A1‘)->setValue(‘John‘);
$worksheet->getCell(‘A2‘)->setValue(‘Smith‘);
//通过工厂模式来写内容
$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, ‘Xls‘);
$writer->save(‘write.xls‘);
为了防止内存泄露,建议用完手动清理
$spreadsheet->disconnectWorksheets();
unset($spreadsheet);
其中A=0 Cell::stringFromColumnIndex($pColumn)
$worksheet->getCell(‘A1‘)->setValue(‘John‘);
$sheet->setCellValue(‘A1‘, ‘Hello World !‘);
$sheet->setCellValueByColumnAndRow($columnIndex, $rowIndex, $value);
$this->getColumnDimension($columnIndex)->setWidth($width);
还可以让其自适应(不靠谱,建议自行设置) $sheet->calculateColumnWidths();
header(‘Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet‘);//告诉浏览器输出07Excel文件
//header(‘Content-Type:application/vnd.ms-excel‘);//告诉浏览器将要输出Excel03版本文件
header(‘Content-Disposition: attachment;filename="01simple.xlsx"‘);//告诉浏览器输出浏览器名称
header(‘Cache-Control: max-age=0‘);//禁止缓存
$writer = new Xlsx($spreadsheet);
$writer->save(‘php://output‘);
function autoFitColumnWidthToContent($sheet, $fromCol, $toCol) {
if (empty($toCol) ) {//not defined the last column, set it the max one
$toCol = $sheet->getColumnDimension($sheet->getHighestColumn())->getColumnIndex();
}
for($i = $fromCol; $i <= $toCol; $i++) {
$sheet->getColumnDimension($i)->setAutoSize(true);
}
$sheet->calculateColumnWidths();
}

$worksheet->setCellValue(‘A12‘, ‘=DMIN(A4:E10,"Profit",A1:A2)‘);
$retVal = $worksheet->getCell(‘A12‘)->getCalculatedValue();
// $retVal = 225
