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);

            $objectPHPExcel->getActiveSheet()->getStyle('B'.($n+4).':G'.$currentRowNum )

        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。
