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。
