TP3.2 phpexcel+TP框架导出

注意事项：1.phpexcel将数据导出到表格 实际上就是下载 前端只能用页面跳转不能用ajax请求

2.可以用href/open/模拟表单(做一个隐藏的form，把数据放入到input中submit事件提交，以下会介绍)

1.下载phpexcel

2.将文件夹放入TP核心文件的 Library->Vendor下面

3.TP里导入PHPExcel    Vendor('PHPExcel.PHPExcel');

注意事项：1.new对象的时候都要加上'\'

4.先把要导出的数据准备好(二维数组)

//导出表格

$objExcel = new \PHPExcel();

$objWriter = \PHPExcel_IOFactory::createWriter($objExcel, 'Excel5');

// 设置水平垂直居中

$objExcel->getActiveSheet()->getDefaultStyle()->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);

$objExcel->getActiveSheet()->getDefaultStyle()->getAlignment()->setVertical(\PHPExcel_Style_Alignment::VERTICAL_CENTER);

// 字体和样式

$objExcel->getActiveSheet()->getDefaultStyle()->getFont()->setSize(10);

$objExcel->getActiveSheet()->getStyle('A2:D2')->getFont()->setBold(true);

$objExcel->getActiveSheet()->getStyle('A1')->getFont()->setBold(true);

// 第一行、第二行的默认高度

$objExcel->getActiveSheet()->getRowDimension('1')->setRowHeight(30);

$objExcel->getActiveSheet()->getRowDimension('2')->setRowHeight(20);

//设置某一列的宽度

$objExcel->getActiveSheet()->getColumnDimension('A')->setWidth(15);

$objExcel->getActiveSheet()->getColumnDimension('B')->setWidth(15);

$objExcel->getActiveSheet()->getColumnDimension('C')->setWidth(25);

//设置表头

//  合并

$objExcel->getActiveSheet()->mergeCells('A1:H1');

$objActSheet = $objExcel->getActiveSheet(0);

$objActSheet->setTitle('场所信息');//设置excel的标题

//注意事项：列是从A B C........ 行就是1 2 3 4 ....

A1就是A列第一行的意思 剩下的同理

$objActSheet->setCellValue('A1','设备信息');

$objActSheet->setCellValue('A2','场所名称');

$objActSheet->setCellValue('B2','设备Mac');

$objActSheet->setCellValue('C2','设备地址');

$objActSheet->setCellValue('D2','楼层');

$objActSheet->setCellValue('E2','最新认证时间');

$objActSheet->setCellValue('F2','心跳时间');

$objActSheet->setCellValue('G2','服务状态');

$objActSheet->setCellValue('H2','数据状态');

$objActSheet->setCellValue('I2','心跳状态');

// //3、填入数据$driver就是要导出的二维数组

$count = count($driver);

//$driver 为数据库表取出的数据

注意事项：

1.for括号里$i等于多取决于你要从第几行循环数据(也就是你表头有几行)

for ($i = 3;$i <= $count+1; $i++){

  $objExcel->getActiveSheet()->setCellValue('A'.$i,$driver[$i-3]['PLACE_NAME']);

  $objExcel->getActiveSheet()->setCellValue('B'.$i,$driver[$i-3]['COLLECTION_EQUIPMENT_MAC']);

  $objExcel->getActiveSheet()->setCellValue('C'.$i,$driver[$i-3]['COLLECTION_EQUIPMENT_ADRESS']);

  $objExcel->getActiveSheet()->setCellValue('D'.$i,$driver[$i-3]['FLOOR']);

  $objExcel->getActiveSheet()->setCellValue('E'.$i,$driver[$i-3]['AUTH_LASTTIME_txt']);

  $objExcel->getActiveSheet()->setCellValue('F'.$i,$driver[$i-3]['Heartbeat_TIME_txt']);

  $objExcel->getActiveSheet()->setCellValue('G'.$i,$driver[$i-3]['service_status_txt']);

  $objExcel->getActiveSheet()->setCellValue('H'.$i,$driver[$i-3]['online']);

  $objExcel->getActiveSheet()->setCellValue('I'.$i,$driver[$i-3]['Heartbeat_status']);

}

//也可以用foreach可能更好  如下：

//也可以这样写 更好

$baseRow = 3; //数据从N-1行开始往下输出 这里是避免头信息被覆盖

foreach ( $driver as $r => $d ) {

      $i = $baseRow + $r;

      $objExcel->getActiveSheet()->setCellValue('A'.$i,$d['PLACE_NAME']);

      $objExcel->getActiveSheet()->setCellValue('B'.$i,$d['ap_num']);

      $objExcel->getActiveSheet()->setCellValue('C'.$i,$d['AREA_CODE_txt']);

      $objExcel->getActiveSheet()->setCellValue('D'.$i,$d['SITE_ADDRESS']);

      $objExcel->getActiveSheet()->setCellValue('E'.$i,$d['NETSITE_TYPE_txt']);

      $objExcel->getActiveSheet()->setCellValue('F'.$i,$d['SECURITY_SOFTWARE_ORGCODE_txt']);

      $objExcel->getActiveSheet()->setCellValue('G'.$i,$d['service_status_txt']);

      $objExcel->getActiveSheet()->setCellValue('H'.$i,$d['online']);

}

$objExcel->setActiveSheetIndex(0);

//4、输出

$objExcel->setActiveSheetIndex();

header('Content-Type: applicationnd.ms-excel');

//filename后面跟的就是要保存的文件名  

//如果文件名是中文要转换编码$filename=iconv('utf-8',"gb2312",$filename);//转换名称编码，防止乱码

header('Content-Disposition: attachment;filename="device.xls"');

header('Cache-Control: max-age=0');

$objWriter->save('php://output');
