1、安装

composer require chenvle/easy_excel

2、使用例子

use Chenvle\EasyExcel\EasyExcel;
$excel = new Excel();
/*导入*/
$var   = [
    'A' => ['key' => 'username', 'title' => '姓名'],
    'B' => ['key' => 'phone', 'title' => '电话'],
    'C' => ['key' => 'origOrderId', 'title' => '订单号'],
    'D' => ['key' => 'txnAmt', 'title' => '订单金额'],
    'E' => ['key' => 'refundAmt', 'title' => '退款金额'],
    'F' => ['key' => 'remark', 'title' => '备注'],
];
$filepath = '***.xlsx';
// 1、excel表路径  2、每列对应数据键名及标题  3、内容开始的行
$excelData  = $excel->input($filepath, $var, 2);
/*导出*/
$field  = [
    'username'    => ['value' => '姓名', 'width' => '15', 'type' => 'string'],
    'school_str'  => ['value' => '学校', 'width' => '15', 'type' => 'string'],
    'grade'       => ['value' => '年级', 'width' => '10', 'type' => 'string'],
    'origOrderId' => ['value' => '订单号', 'width' => '25', 'type' => 'string'],
    'title'       => ['value' => '项目名称', 'width' => '30', 'type' => 'string', 'with' => 'orderInfo'],

$str    = '待退款表';
$data = [];//导出的数据
//输出到浏览器
$excel->output($data, $str, $field,'Xlsx');

//保存到服务器返回路径(前面不用'/'，后面也不用"/")
$url = $excel->output($data, $str, $field,'Xlsx','upload');
