如何实现Yii2框架中使用PHPExcel导出Excel文件

本篇文章主要介绍了Yii2框架中使用PHPExcel导出Excel文件的相关资料,具有一定的参考价值，感兴趣的小伙伴们可以参考一下

最近在研究PHP的Yii框架，很喜欢，碰到导出Excel的问题，研究了一下，就有了下面的方法：

最简单的利用composer安装

composer require "phpoffice/phpexcel": "*"

如果没有安装conposer可以参考下面1.2步

1、引入PHPExcel

首先得要下载phpexcel地址:https://github.com/PHPOffice/PHPExcel/archive/1.8.1.zip

你可以直接在入口文件index.php中引入，也可以在你定义的controller类之前，只要是在你使用之前引入就可以

require dirname(dirname(__FILE__)).'/excel/PHPExcel.php';

或者在phpexcel类里修改相应的namespace也可。

2、按照下面的代码修改PHPExcel代码目录里的Autoloader.php文件，对比源文件改成：

public static function Register() {  $functions = spl_autoload_functions();  foreach ( $functions as $function)    spl_autoload_unregister($function);    $functions = array_merge(array(array('PHPExcel_Autoloader','Load')),$functions);  foreach ( $functions as $function)    $x = spl_autoload_register($function);    return $x;}

上面的函数中，注释掉的是原有的代码。

3、下面的代码是输出Excel，以及一些常用的属性设置，在controller中：

public function actionExport(){    $objectPHPExcel = new PHPExcel();    $objectPHPExcel->setActiveSheetIndex(0);      $page_size = 52;    $model = new NewsSearch();    $dataProvider = $model->search();    $dataProvider->setPagination(false);    $data = $dataProvider->getData();    $count = $dataProvider->getTotalItemCount();    $page_count = (int)($count/$page_size) +1;    $current_page = 0;    $n = 0;    foreach ( $data as $product )    {      if ( $n % $page_size === 0 )      {        $current_page = $current_page +1;          //报表头的输出        $objectPHPExcel->getActiveSheet()->mergeCells('B1:G1');        $objectPHPExcel->getActiveSheet()->setCellValue('B1','产品信息表');          $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('B2','产品信息表');        $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('B2','产品信息表');        $objectPHPExcel->setActiveSheetIndex(0)->getStyle('B1')->getFont()->setSize(24);        $objectPHPExcel->setActiveSheetIndex(0)->getStyle('B1')          ->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);          $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('B2','日期：'.date("Y年m月j日"));        $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('G2','第'.$current_page.'/'.$page_count.'页');        $objectPHPExcel->setActiveSheetIndex(0)->getStyle('G2')          ->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);                  //表格头的输出        $objectPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(5);   <i style="color:transparent">本#文来源gaodai$ma#com搞$$代**码网$</i><button>搞代gaodaima码</button>     $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('B3','编号');        $objectPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(6.5);        $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('C3','名称');        $objectPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(17);        $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('D3','生产厂家');        $objectPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(22);        $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('E3','单位');        $objectPHPExcel->getActiveSheet()->getColumnDimension('E')->setWidth(15);        $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('F3','单价');        $objectPHPExcel->getActiveSheet()->getColumnDimension('F')->setWidth(15);        $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('G3','在库数');        $objectPHPExcel->getActiveSheet()->getColumnDimension('G')->setWidth(15);                  //设置居中        $objectPHPExcel->getActiveSheet()->getStyle('B3:G3')          ->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);          //设置边框        $objectPHPExcel->getActiveSheet()->getStyle('B3:G3' )          ->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);        $objectPHPExcel->getActiveSheet()->getStyle('B3:G3' )          ->getBorders()->getLeft()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);        $objectPHPExcel->getActiveSheet()->getStyle('B3:G3' )          ->getBorders()->getRight()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);        $objectPHPExcel->getActiveSheet()->getStyle('B3:G3' )          ->getBorders()->getBottom()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);        $objectPHPExcel->getActiveSheet()->getStyle('B3:G3' )          ->getBorders()->getVertical()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);          //设置颜色        $objectPHPExcel->getActiveSheet()->getStyle('B3:G3')->getFill()          ->setFillType(PHPExcel_Style_Fill::FILL_SOLID)->getStartColor()->setARGB('FF66CCCC');                }      //明细的输出      $objectPHPExcel->getActiveSheet()->setCellValue('B'.($n+4) ,$product->id);      $objectPHPExcel->getActiveSheet()->setCellValue('C'.($n+4) ,$product->product_name);      $objectPHPExcel->getActiveSheet()->setCellValue('D'.($n+4) ,$product->product_agent->name);      $objectPHPExcel->getActiveSheet()->setCellValue('E'.($n+4) ,$product->unit);      $objectPHPExcel->getActiveSheet()->setCellValue('F'.($n+4) ,$product->unit_price);      $objectPHPExcel->getActiveSheet()->setCellValue('G'.($n+4) ,$product->library_count);      //设置边框      $currentRowNum = $n+4;      $objectPHPExcel->getActiveSheet()->getStyle('B'.($n+4).':G'.$currentRowNum )          ->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);      $objectPHPExcel->getActiveSheet()->getStyle('B'.($n+4).':G'.$currentRowNum )          ->getBorders()->getLeft()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);      $objectPHPExcel->getActiveSheet()->getStyle('B'.($n+4).':G'.$currentRowNum )          ->getBorders()->getRight()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);      $objectPHPExcel->getActiveSheet()->getStyle('B'.($n+4).':G'.$currentRowNum )          ->getBorders()->getBottom()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);      $objectPHPExcel->getActiveSheet()->getStyle('B'.($n+4).':G'.$currentRowNum )          ->getBorders()->getVertical()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);      $n = $n +1;      }      //设置分页显示    //$objectPHPExcel->getActiveSheet()->setBreak( 'I55' , PHPExcel_Worksheet::BREAK_ROW );    //$objectPHPExcel->getActiveSheet()->setBreak( 'I10' , PHPExcel_Worksheet::BREAK_COLUMN );    $objectPHPExcel->getActiveSheet()->getPageSetup()->setHorizontalCentered(true);    $objectPHPExcel->getActiveSheet()->getPageSetup()->setVerticalCentered(false);        ob_end_clean();    ob_start();      header('Content-Type : application/vnd.ms-excel');    header('Content-Disposition:attachment;filename="'.'产品信息表-'.date("Y年m月j日").'.xls"');    $objWriter= PHPExcel_IOFactory::createWriter($objectPHPExcel,'Excel5');    $objWriter->save('php://output');
