$file=$this->request->file('excel');
            $root_path=Env::get('root_path');
            $src=$root_path.'public/upload/excel';
            $info=$file->validate(['ext'=>'xlsx,xls,csv'])->move($src);
            $array['fileType']=1;
    
            //excel表格
            include($root_path.'extend/PHPExcel/Classes/PHPExcel.php');
            if($info){
                $extension=$info->getExtension();
                $src.='\\'.$info->getSaveName();
                $file_name = $src;   //上传文件的地址
                $objReader =\PHPExcel_IOFactory::createReader('Excel5');
                
                if ($extension =='xlsx') {
                    $objReader =\PHPExcel_IOFactory::createReader('Excel2007');
                    $obj_PHPExcel =$objReader->load($file_name, $encode = 'utf-8');  //加载文件内容,编码utf-8
                } else if ($extension =='xls') {
                    $objReader =\PHPExcel_IOFactory::createReader('Excel5');
                    $obj_PHPExcel =$objReader->load($file_name, $encode = 'utf-8');  //加载文件内容,编码utf-8
                } else if ($extension=='csv') {
                    $objReader = \PHPExcel_IOFactory::createReader('CSV');
                    $obj_PHPExcel = $objReader->setInputEncoding('GBK')->load($file_name);
                }
                 echo "<pre>";
                $excel_array=$obj_PHPExcel->getsheet(0)->toArray();   //转换为数组格式
                // array_shift($excel_array);  //删除第一个数组(标题);
                foreach($excel_array as $k=>$v) {
                    dump($v);
                }
            } else {
                echo $file->getError();
            }

下面是总结的几个使用方法
    include 'PHPExcel.php';
    include 'PHPExcel/Writer/Excel2007.php';
    //或者include 'PHPExcel/Writer/Excel5.php'; 用于输出.xls的
    创建一个excel
    $objPHPExcel = new PHPExcel();
    保存excel—2007格式
    $objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
    //或者$objWriter = new PHPExcel_Writer_Excel5($objPHPExcel); 非2007格式
    $objWriter->save("xxx.xlsx");
    直接输出到浏览器
    $objWriter = new PHPExcel_Writer_Excel5($objPHPExcel);
    header("Pragma: public");
    header("Expires: 0″);
    header("Cache-Control:must-revalidate, post-check=0, pre-check=0″);
    header("Content-Type:application/force-download");
    header("Content-Type:application/vnd.ms-execl");
    header("Content-Type:application/octet-stream");
    header("Content-Type:application/download");;
    header('Content-Disposition:attachment;filename="resume.xls"');
    header("Content-Transfer-Encoding:binary");
    $objWriter->save('php://output');

    $objPHPExcel->getActiveSheet()->getStyle('D13')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);
    $objPHPExcel->getActiveSheet()->getStyle('A18')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_JUSTIFY);
    //垂直居中
    $objPHPExcel->getActiveSheet()->getStyle('A18')->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER);
    设置column的border

    $objPHPExcel->getActiveSheet()->getStyle('C4')->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);

    $objPHPExcel->getActiveSheet()->getStyle('B1')->getFill()->setFillType(PHPExcel_Style_Fill::FILL_SOLID);
    $objPHPExcel->getActiveSheet()->getStyle('B1')->getFill()->getStartColor()->setARGB('FF808080');
    加图片
    $objDrawing = new PHPExcel_Worksheet_Drawing();
    $objDrawing->setName('Logo');
    $objDrawing->setDescription('Logo');
    $objDrawing->setPath('./images/officelogo.jpg');
    $objDrawing->setHeight(36);
    $objDrawing->setWorksheet($objPHPExcel->getActiveSheet());
    $objDrawing = new PHPExcel_Worksheet_Drawing();
    $objDrawing->setName('Paid');
    $objDrawing->setDescription('Paid');
    $objDrawing->setPath('./images/paid.png');
    $objDrawing->setCoordinates('B15');
    $objDrawing->setOffsetX(110);
    $objDrawing->setRotation(25);
    $objDrawing->getShadow()->setVisible(true);
    $objDrawing->getShadow()->setDirection(45);
    $objDrawing->setWorksheet($objPHPExcel->getActiveSheet());
    //处理中文输出问题
    需要将字符串转化为UTF-8编码，才能正常输出，否则中文字符将输出为空白，如下处理：
     $str  = iconv('gb2312', 'utf-8', $str);
    或者你可以写一个函数专门处理中文字符串：
    function convertUTF8($str)
    {
       if(empty($str)) return '';
       return  iconv('gb2312', 'utf-8', $str);
    }
    //从数据库输出数据处理方式
    从数据库读取数据如：
    $db = new Mysql($dbconfig);
    $sql = "SELECT * FROM  表名";
    $row = $db->GetAll($sql);  // $row 为二维数组
    $count = count($row);
    for ($i = 2; $i <= $count+1; $i++) {
     $objPHPExcel->getActiveSheet()->setCellValue('A' . $i, convertUTF8($row[$i-2][1]));
     $objPHPExcel->getActiveSheet()->setCellValue('B' . $i, convertUTF8($row[$i-2][2]));
     $objPHPExcel->getActiveSheet()->setCellValue('C' . $i, convertUTF8($row[$i-2][3]));
     $objPHPExcel->getActiveSheet()->setCellValue('D' . $i, convertUTF8($row[$i-2][4]));
     $objPHPExcel->getActiveSheet()->setCellValue('E' . $i, convertUTF8(date("Y-m-d", $row[$i-2][5])));
     $objPHPExcel->getActiveSheet()->setCellValue('F' . $i, convertUTF8($row[$i-2][6]));
     $objPHPExcel->getActiveSheet()->setCellValue('G' . $i, convertUTF8($row[$i-2][7]));
     $objPHPExcel->getActiveSheet()->setCellValue('H' . $i, convertUTF8($row[$i-2][8]));
    }
     
    在默认sheet后，创建一个worksheet
    echo date('H:i:s') . " Create new Worksheet object\n";
    $objPHPExcel->createSheet();
    $objWriter = PHPExcel_IOFactory::createWriter($objExcel, 'Excel5');
    $objWriter-save('php://output');
