Yii2框架中PHPExcel导出Excel文件方法

本文主要介绍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，希望能帮助到大家。

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。
