• 首先是使用PHP Reader 读取Excle内容：

1 require("http://www.cnblogs.com/PHPExcel/Classes/PHPExcel.php"); 2 $file = "D:\\datas.xlsx"; 3 if(!file_exists($file)){ 4     die("no file found in {
   $file}"); 5 } 6 $datasReader = PHPExcel_IOFactory::load($file); 7 $sheets = $datasReader->getAllSheets(); 8 //如果有多个工作簿 9 $countSheets = count($sheets);10 $sheetsinfo = array();11 $sheetData = array();12 if($countSheets==1){13     $sheet = $sheets[0];    14     $sheetsinfo["rows"] = $sheet->getHighestRow();15     $sheetsinfo["column"] = PHPExcel_Cell::columnIndexFromString($sheet->getHighestColumn());16     for($row=1;$row<=$sheetsinfo["rows"];$row++){17         for($column=0;$column<$sheetsinfo["column"];$column++){18             $sheetData[$column][$row] = $sheet->getCellByColumnAndRow($column, $row)->getValue();19         }20     }21 }else{    22     foreach ($sheets as $key => $sheet) 23     {24         $sheetsinfo[$key]["rows"] = $sheet->getHighestRow();25         $sheetsinfo[$key]["column"] = PHPExcel_Cell::columnIndexFromString($sheet->getHighestColumn());        26         for($row=1;$row<=$sheetsinfo[$key]["rows"];$row++){27             for($column=0;$column<$sheetsinfo[$key]["column"];$column++){28                 $sheetData[$key][$column][$row] = $sheet->getCellByColumnAndRow($column, $row)->getValue();29             }30         }31     }32 }33 echo "
";34 print_r($sheetData);35 echo "
";

注：使用PHP 读取excel文件内容，一般都是处理整理好格式的csv或者excel，也可以读取xml文件

• PHPExcel生成Exceel

$sql = sprintf("select * from table where op_id=%d",  intval($this->params['id']));        $query = $this->_db->query($sql);        require_once './PHPExcel_1.7.4/Classes/PHPExcel.php';        $objPHPExcel = new PHPExcel();        $objPHPExcel->setActiveSheetIndex(0);        $objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(10);        $objPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(15);        $objPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(15);        $objPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(15);        $objPHPExcel->getActiveSheet()->getColumnDimension('E')->setWidth(15);        $objPHPExcel->getActiveSheet()->setCellValue('A1', "{
   $this->_packInfos['o_id']}");        $objPHPExcel->getActiveSheet()->setCellValue('B1', "Volume weight (kg)");        $objPHPExcel->getActiveSheet()->setCellValue('D1', "Actual weight (kg)");                $objPHPExcel->getActiveSheet()->setCellValue('A2', "Box No.");        $objPHPExcel->getActiveSheet()->setCellValue('B2', "Products");        $objPHPExcel->getActiveSheet()->setCellValue('C2', "Shipping Box");        $objPHPExcel->getActiveSheet()->setCellValue('D2', "System");        $objPHPExcel->getActiveSheet()->setCellValue('E2', "Input");        $objActSheet = $objPHPExcel->getActiveSheet();        $objActSheet->mergeCells("B1:C1");        $objActSheet->mergeCells("D1:E1");                $objPHPExcel->getActiveSheet()->getStyle('A1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_LEFT);        $objPHPExcel->getActiveSheet()->getStyle('B1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);        $objPHPExcel->getActiveSheet()->getStyle('D1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);                $objPHPExcel->getActiveSheet()->getStyle('A2'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_LEFT);        $objPHPExcel->getActiveSheet()->getStyle('B2'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);        $objPHPExcel->getActiveSheet()->getStyle('C2'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);        $objPHPExcel->getActiveSheet()->getStyle('D2'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);        $objPHPExcel->getActiveSheet()->getStyle('E2'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);                if($this->_db->num_rows($query)>0)        {            $i=3;            while ($row = $this->_db->fetch_assoc($query))            {                $objPHPExcel->getActiveSheet()->setCellValue('A'.($i),"BOX ".$row['box_num']);                $objPHPExcel->getActiveSheet()->setCellValue('B'.($i),sprintf("%.2f",$row['volume_weight']));                $objPHPExcel->getActiveSheet()->setCellValue('C'.($i),sprintf("%.2f",$row['box_weight']));                $objPHPExcel->getActiveSheet()->setCellValue('D'.($i),sprintf("%.2f",$row['system_weight']));                $objPHPExcel->getActiveSheet()->setCellValue('E'.($i),sprintf("%.2f",$row['real_weight']));                                $objPHPExcel->getActiveSheet()->getStyle('A'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_LEFT);                $objPHPExcel->getActiveSheet()->getStyle('B'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);                $objPHPExcel->getActiveSheet()->getStyle('C'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);                $objPHPExcel->getActiveSheet()->getStyle('D'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);                $objPHPExcel->getActiveSheet()->getStyle('E'.($i))->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);                $i++;            }        }                $fileName="exportBox.xls";        $filePath = dirname(dirname("__FILE__"))."/template/".$fileName;        $path = "./template/".$fileName;        $objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);                if(file_exists($path)){            chmod($path, 0777);            unlink($path);            $objWriter->save($path);             header('application/vnd.ms-excel');            header('Content-Disposition: attachment;filename=weight-'.$this->_packInfos["o_id"].".xlsx");            readfile($filePath);                  die();        }        else         {            $objWriter->save($path);             header('application/vnd.ms-excel');            header('Content-Disposition: attachment;filename=weight-'.$this->_packInfos["o_id"].".xlsx");            readfile($filePath);                 die();        }

注：上面的php生成excel的方式是直接使用A标签形式的，如果使用ajax，可以不使用header，直接echo $path,前台window.location.href=返回来的path就可以了。
