安装类库

从GitHub上下载PHPExcel类库
地址：https://github.com/PHPOffice/PHPExcel

解压后将Classes文件夹移动到ThinkPHP的extend目录，并将其重命名为phpexcel

在项目中需要的地方添加引用

import('phpexcel.PHPExcel', EXTEND_PATH);

代码实现

<?php
namespace app\index\controller;use think\Controller;class Excel extends Controller
{// 将数据导出至Excelpublic function exportExcel(){// 引入类库import('phpexcel.PHPExcel', EXTEND_PATH);// 文件名和文件类型$fileName = "student";$fileType = "xlsx";// 模拟获取数据$data = self::getData();$obj = new \PHPExcel();// 以下内容是excel文件的信息描述信息$obj->getProperties()->setCreator(''); //设置创建者$obj->getProperties()->setLastModifiedBy(''); //设置修改者$obj->getProperties()->setTitle(''); //设置标题$obj->getProperties()->setSubject(''); //设置主题$obj->getProperties()->setDescription(''); //设置描述$obj->getProperties()->setKeywords('');//设置关键词$obj->getProperties()->setCategory('');//设置类型// 设置当前sheet$obj->setActiveSheetIndex(0);// 设置当前sheet的名称$obj->getActiveSheet()->setTitle('student');// 列标$list = ['A', 'B', 'C'];// 填充第一行数据$obj->getActiveSheet()->setCellValue($list[0] . '1', '学号')->setCellValue($list[1] . '1', '姓名')->setCellValue($list[2] . '1', '班级');// 填充第n(n>=2, n∈N*)行数据$length = count($data);for ($i = 0; $i < $length; $i++) {$obj->getActiveSheet()->setCellValue($list[0] . ($i + 2), '20190101', \PHPExcel_Cell_DataType::TYPE_STRING);//将其设置为文本格式$obj->getActiveSheet()->setCellValue($list[1] . ($i + 2), 'student01');$obj->getActiveSheet()->setCellValue($list[2] . ($i + 2), '1班');}// 设置加粗和左对齐foreach ($list as $col) {// 设置第一行加粗$obj->getActiveSheet()->getStyle($col . '1')->getFont()->setBold(true);// 设置第1-n行，左对齐for ($i = 1; $i <= $length + 1; $i++) {$obj->getActiveSheet()->getStyle($col . $i)->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_LEFT);}}// 设置列宽$obj->getActiveSheet()->getColumnDimension('A')->setWidth(20);$obj->getActiveSheet()->getColumnDimension('B')->setWidth(20);$obj->getActiveSheet()->getColumnDimension('C')->setWidth(15);// 导出ob_clean();if ($fileType == 'xls') {header('Content-Type: application/vnd.ms-excel');header('Content-Disposition: attachment;filename="' . $fileName . '.xls');header('Cache-Control: max-age=1');$objWriter = new \PHPExcel_Writer_Excel5($obj);$objWriter->save('php://output');exit;} elseif ($fileType == 'xlsx') {header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');header('Content-Disposition: attachment;filename="' . $fileName . '.xlsx');header('Cache-Control: max-age=1');$objWriter = \PHPExcel_IOFactory::createWriter($obj, 'Excel2007');$objWriter->save('php://output');exit;}}// 准备数据protected function getData(){$studentList = [['stuNo' => '20190101','name' => 'student01','class' => '1班'], ['stuNo' => '20190102','name' => 'student02','class' => '1班'], ['stuNo' => '20190103','name' => 'student03','class' => '1班']];return $studentList;}
}

运行

浏览器访问http://127.0.0.1:8083/index/excel/exportExcel下载Excel文件

打开文件如下:

可以看到Excel中的数据和PHP数组中的数据是一致的！
