PHP phpoffice/phpspreadsheet导出excel

PHP phpoffice/phpspreadsheet导出excel

由于PHPExcel已经被废弃在PHP7.2中已经无法获取更新，官方重新开了一个新包phpspreadsheet
注意：这里使用的是tp6框架做测试

第一步：使用composer在根项目下安装phpspreadsheet
安装命令：composer require phpoffice/phpspreadsheet
安装成功后，会在vendor目录下成一个目录：phpoffice

第二步：后端代码处理
注意：顶部引入第三方类库
use PhpOffice\PhpSpreadsheet\Spreadsheet;

- 代码：
/*

  /*
    * 数据处理
    */
    public function derive()
    {
        //需导出的数据,多条数据
        $data = [
            [
                'time' => '时间',
                'order_num' => '付款人数',

        $this->downloadExcel($xlsName, $data, $head, $keys);// 传递参数

    }

        }
        //循环设置单元格：
        foreach ($data as $key => $item) {
            //$key+2,因为第一行是表头，所以写到表格时   从第二行开始写
            for ($i = 65; $i < $count + 65; $i++) {
                //数字转字母从65开始：
                $sheet->setCellValue(strtoupper(chr($i)) . ($key + 2), $item[$keys[$i - 65]]);

        $str = '';

        for ($i = 0; $i < $len - 1; $i = $i + 2) {

        $writer->save('php://output');
        exit;

    }

设置Excel表格样式

$sheet = $spreadsheet->getActiveSheet();


 // 合并单元格
$sheet->mergeCells('A1:L1');
  
// 设置单元格值
$sheet->setCellValue('A1',$value);
  
//设值行高
$sheet->getRowDimension('1')->setRowHeight(16);
  
//设置表头信息字体大小
$sheet->getCell('A1')->getStyle()->getFont()->setSize(12);
  
//设置所有字体
$spreadsheet->getDefaultStyle()->getFont()->setName('微软雅黑');
  
//设置水平默认对齐方式
$spreadsheet->getDefaultStyle()->getAlignment()
   ->setHorizontal(\PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_CENTER);
   
//设置垂直默认对齐方式
$spreadsheet->getDefaultStyle()->getAlignment()
	   ->setVertical(\PhpOffice\PhpSpreadsheet\Style\Alignment::VERTICAL_CENTER);
//设置外边框和内边框
$styleArray = [
			   'borders' => [
				   'outline' => [
					   'borderStyle' => \PhpOffice\PhpSpreadsheet\Style\Border::BORDER_THICK,
				   ],
				   'inside' =>[
					   'borderStyle' => \PhpOffice\PhpSpreadsheet\Style\Border::BORDER_THIN,
				   ]
			   ],
		   ];

$sheet->getStyle('A1:L20')->applyFromArray($styleArray);
//设置列宽
$spreadsheet->getActiveSheet()->getColumnDimension('H')->setWidth(14);
   
//设置单元格为文本格式
$sheet->getCell('A'.$row)->getStyle()->getNumberFormat()->setFormatCode(NumberFormat::FORMAT_TEXT);

//新增一个sheet
$sheet = $spreadsheet->createSheet();
//设置字体颜色
$sheet->getCell("B$startRow")->getStyle()->getFont()
                    ->getColor()->setARGB(\PhpOffice\PhpSpreadsheet\Style\Color::COLOR_RED);
 //字体加粗
    $sheet->getCell("A$startRow")->getStyle()->getFont()->setBold(true);                   
//设置单元格背景色
   $spreadsheet->getActiveSheet()->getStyle($column .($beginRow))->getFill()
                        ->setFillType(\PhpOffice\PhpSpreadsheet\Style\Fill::FILL_SOLID)
                        ->getStartColor()->setARGB('FF9800');
//设置公式
$sheet->setCellValue(
                        "C1",
                        "=SUM(F1:F10)"
                    );
                   
		
		
		
		
		

到这PHP 使用phpoffice/phpspreadsheet导出excel就完成了，后需可以根据自己业务需要做对应的调整
