想用TP6使用phpspreadsheet但是说我PHP版本低，原来是PHP7.0  composer要求至少7.4

直接修改环境变量，把PHP目录切换到7.4

composer升级比较简单，在PHP目录下CMD然后官网的命令执行下即可

下面就可以在TP根目录下执行命令安装PHPSPREADSHEET

程序就简单了

use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\IOFactory;$spreadsheet = new Spreadsheet();// 获取活动工作薄$sheet = $spreadsheet->getActiveSheet();// 获取单元格$cellA = $sheet->getCell('A1');// 设置单元格的值$cellA->setValue('姓名');// 设置 A 列 列宽$sheet->getColumnDimension('A')->setWidth(30);// 设置第一行 行高$sheet->getRowDimension(1)->setRowHeight(20);$cellB = $sheet->getCell('B1');$cellB->setValue('手机号');$sheet->getColumnDimension('B')->setWidth(30);$cellC = $sheet->getCell('C1');$cellC->setValue('学历');$sheet->getColumnDimension('C')->setWidth(30);$cellD = $sheet->getCell('D1');$cellD->setValue('考试目的');$sheet->getColumnDimension('D')->setWidth(30);$cellE = $sheet->getCell('E1');$cellE->setValue('考试方式');$sheet->getColumnDimension('E')->setWidth(30);$cellF = $sheet->getCell('F1');$cellF->setValue('报名时间');$sheet->getColumnDimension('F')->setWidth(30);$cellG = $sheet->getCell('G1');$cellG->setValue('来源');$sheet->getColumnDimension('G')->setWidth(30);// 设置样式 标题栏$styleArray = ['alignment' => ['horizontal' => 'center', //水平居中'vertical' => 'center', //垂直居中],'font' => ['name' => '黑体','bold' => false,'size' => 10]];// 设置样式 正文$styleArrayBody = ['alignment' => ['horizontal' => 'center', //水平居中'vertical' => 'center', //垂直居中],'font' => ['name' => '宋体','bold' => false,'size' => 10]];// 应用样式$sheet->getStyle('A1')->applyFromArray($styleArray);$sheet->getStyle('B1')->applyFromArray($styleArray);$sheet->getStyle('C1')->applyFromArray($styleArray);$sheet->getStyle('D1')->applyFromArray($styleArray);$sheet->getStyle('E1')->applyFromArray($styleArray);$sheet->getStyle('F1')->applyFromArray($styleArray);$sheet->getStyle('G1')->applyFromArray($styleArray);// 从 A2 开始填充数据foreach ($data as $k => $v) {if($v['aid'] == 99999){$laiyuan = "专题";}else{$laiyuan = "文章";}$n = $k + 2;// 获取单元格$cellA = $sheet->getCell('A'.$n);// 设置单元格的值$cellA->setValue($v['uname']);$cellB = $sheet->getCell('B'.$n);$cellB->setValue($v['phone']);$cellC = $sheet->getCell('C'.$n);$cellC->setValue($v['xueli']);$cellD = $sheet->getCell('D'.$n);$cellD->setValue($v['mudi']);$cellE = $sheet->getCell('E'.$n);$cellE->setValue($v['fangshi']);$cellF = $sheet->getCell('F'.$n);$cellF->setValue($v['createtime']);$cellG = $sheet->getCell('G'.$n);$cellG->setValue($laiyuan);// 再给表格体设置样式$sheet->getStyle('A'.$n)->applyFromArray($styleArrayBody);$sheet->getStyle('B'.$n)->applyFromArray($styleArrayBody);$sheet->getStyle('C'.$n)->applyFromArray($styleArrayBody);$sheet->getStyle('D'.$n)->applyFromArray($styleArrayBody);$sheet->getStyle('E'.$n)->applyFromArray($styleArrayBody);$sheet->getStyle('F'.$n)->applyFromArray($styleArrayBody);$sheet->getStyle('G'.$n)->applyFromArray($styleArrayBody);}// MIME 协议的扩展$filename = date('Y-m-d').'报名表单.xlsx';header('Content-Type:application/vnd.ms-excel');header('Content-Disposition:attachment;filename='.$filename);header('Cache-Control:max-age=0');$writer = IOFactory::createWriter($spreadsheet, 'Xlsx');$writer->save('php://output');
