Yii2框架中使用PHPExcel导出Excel文件的示例

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);
 $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');

代码执行后，会直接生成Excel，并提示下载或打开。
