在日常开发中，我们会遇到大批量的数据导出以及导入，之前的PHP旧库现在已经停更了，如下提示：
composer require phpoffice/phpexcel
Package phpoffice/phpexcel is abandoned, you should avoid using it. Use phpoffice/phpspreadsheet instead.
phpoffice/phpexcel包已废弃，应避免使用。请改用phpoffice/phpspreadsheet。
所以我们应该按照提示进行操作，在项目的目录下，也就是vendor的上一级目录下执行：
composer require phpoffice/phpspreadsheet
等待安装完成后即刻进行在所需要使用的控制中引入类以及在extend目录下新建Excel.php文件： 下载EXCEL
<?php
use \PhpOffice\PhpSpreadsheet\Spreadsheet;
use \PhpOffice\PhpSpreadsheet\IOFactory;
class Excel
{
//execl模板下载
public function template_download($studentList = '')
{
$newExcel = new Spreadsheet(); //创建一个新的excel文档
$objSheet = $newExcel->getActiveSheet(); //获取当前操作sheet的对象
$objSheet->setTitle('销售号码池'); //设置当前sheet的标题
//设置宽度为true,不然太窄了
$newExcel->getActiveSheet()->getColumnDimension('A')->setAutoSize(true);
$newExcel->getActiveSheet()->getColumnDimension('B')->setAutoSize(true);
$newExcel->getActiveSheet()->getColumnDimension('C')->setAutoSize(true);
$newExcel->getActiveSheet()->getColumnDimension('D')->setAutoSize(true);
$newExcel->getActiveSheet()->getColumnDimension('E')->setAutoSize(true);
$newExcel->getActiveSheet()->getColumnDimension('F')->setAutoSize(true);
$newExcel->getActiveSheet()->getColumnDimension('G')->setAutoSize(true);
$newExcel->getActiveSheet()->getColumnDimension('H')->setAutoSize(true);
$newExcel->getActiveSheet()->getColumnDimension('I')->setAutoSize(true);
//设置第一栏的标题
$objSheet->setCellValue('A1', 'ID')
->setCellValue('B1', '企业名称')
->setCellValue('C1', '企业类型')
->setCellValue('D1', '归属地')
->setCellValue('E1', '客户姓名')
->setCellValue('F1', '手机号码')
->setCellValue('G1', '企业编号')
->setCellValue('H1', '公司地址');
if($studentList === '')
{
//默认数据
$explame_data_list = array(
array(
's_nid' => '1',
's_name' => '小明',
's_number' => '18866886688',
's_area' => '中国',
's_companyName' => '文化有限有限公司',
's_companyType' => '公司/个体',
's_companyCode' => 'MA88888888888',
's_address' => '地球村'
),
);
}
else
{
$explame_data_list = $studentList;
}
$baseRow = 2; //数据从N-1行开始往下输出 这里是避免头信息被覆盖
foreach ($explame_data_list as $k => $val) {
$i = $k + $baseRow;
$objSheet->setCellValue('A' . $i, $val['s_nid'])
->setCellValue('B' . $i, $val['s_companyName'])
->setCellValue('C' . $i, $val['s_companyType'])
->setCellValue('D' . $i, $val['s_area'])
->setCellValue('E' . $i, $val['s_name'])
->setCellValue('F' . $i, $val['s_number'])
->setCellValue('G' . $i, $val['s_companyCode'])
->setCellValue('H' . $i, $val['s_address']);
}
$this->downloadExcel($newExcel, '客户电话资料', 'Xls');
}
//公共文件，用来传入xls并下载
private function downloadExcel($newExcel, $filename, $format)
{
// $format只能为 Xlsx 或 Xls
if ($format == 'Xlsx') {
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
} elseif ($format == 'Xls') {
header('Content-Type: application/vnd.ms-excel');
}
header("Content-Disposition: attachment;filename="
. $filename . date('Y-m-d') . '.' . strtolower($format));
header('Cache-Control: max-age=0');
$objWriter = IOFactory::createWriter($newExcel, $format);
$objWriter->save('php://output');
//通过php保存在本地的时候需要用到
//$objWriter->save($dir.'/demo.xlsx');
//以下为需要用到IE时候设置
// If you're serving to IE 9, then the following may be needed
//header('Cache-Control: max-age=1');
// If you're serving to IE over SSL, then the following may be needed
//header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
//header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT'); // always modified
//header('Cache-Control: cache, must-revalidate'); // HTTP/1.1
//header('Pragma: public'); // HTTP/1.0
exit;
}
}
上传导入Excel
在需要用到的控制器中只需要引入类库以及excel.php
<?php
namespace app\controller;
use Excel;
use \PhpOffice\PhpSpreadsheet\Spreadsheet;
use \PhpOffice\PhpSpreadsheet\IOFactory;
public function uploadExcelNumber()
{
if(!Request()->isPost())
{
return View::fetch('Numberhub/uploadExcel');
}
header("content-type:text/html;charset=utf-8");
$isFile = $_FILES;
if($isFile['file']['name'] === '')
{
return json(['code'=>201,'msg'=>'请上传要导入的文件']);
}
$file = request()->file();
try {
validate(['file'=>'fileSize:10240000|fileExt:xls'])->check($file);
$file = request()->file('file');
// 上传到本地服务器
$savename = Filesystem::disk('public')->putFile( 'topic', $file);
//获取文件路径
$filePath = app()->getRootPath() . 'public/storage' . DIRECTORY_SEPARATOR . $savename;
// 有Xls和Xlsx格式两种
$reader = IOFactory::createReader('Xls');
} catch (\think\exception\ValidateException $e) {
return json(['code'=>201,'msg'=>$e->getMessage()]);
}
//载入excel文件
$excel = $reader->load($filePath);
//读取第一张表
$sheet = $excel->getSheet(0);
//获取总行数
$row_num = $sheet->getHighestRow();
//获取总列数
//$col_num = $sheet->getHighestColumn();
$import_data = []; //数组形式获取表格数据
for ($i = 2; $i <= $row_num; $i++) {
$arr = [
's_companyName' => $excel->getActiveSheet()->getCell("B" . $i)->getValue(),
's_companyType' => $excel->getActiveSheet()->getCell("C" . $i)->getValue(),
's_area' => $excel->getActiveSheet()->getCell("D" . $i)->getValue(),
's_name'=> $excel->getActiveSheet()->getCell("E" . $i)->getValue(),
's_date' => Date('Y-m-d'),
's_number' => $excel->getActiveSheet()->getCell("F" . $i)->getValue(),
's_companyCode' => $excel->getActiveSheet()->getCell("G" . $i)->getValue(),
's_address' => $excel->getActiveSheet()->getCell("H" . $i)->getValue()
];
array_push($import_data,$arr);
}
if (empty($import_data)) {
return json(['status' => '1', 'message' => '数据解析失败']);
}
//将数据保存到数据库
$numberInfo = new Numberpool;
for($v = 0;$v<count($import_data);$v++)
{
if($import_data[$v]['s_companyName'] === null)
{
$import_data[$v]['s_companyName'] = '';
}
if($import_data[$v]['s_companyCode'] === null)
{
$import_data[$v]['s_companyCode'] = '';
}
if($import_data[$v]['s_address'] === null)
{
$import_data[$v]['s_address'] = '';
}
$numberInfo->create($import_data[$v]);
}
unlink($filePath);
return json(['code'=>200,'msg'=>'导入成功']);
}
以上就是在TP6中使用phpspreadsheet库进行EXCEL的数据导入导出，后续所需要的优化可根据自己的需求进行处理，比如上传去重等。 但是友情提醒一点是，如果批量导入的数据比较大，需要进行分段导入，使用ajax分段或者使用缓存技术，将数据慢慢导入避免超时及压力太大造成系统崩溃。
