安装类库

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

namespace app\index\controller;

use think\Controller;

class Excel extends Controller

{

// 将数据导出至Excel

public 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！
