thinkphp3.2.3结合PHPExcel导出数据库里所有表的结构

jerry thinkphp 2015年11月19日收藏

前面已经做过了一个关于这方面的demo,但没有对excel进行格式设置,用户体验不友好,这次做了改正,希望在项目开发的时候,大家能用得上.
按惯例,先上图

代码如下:

  public function out(){    

        //读取库里所有的表            

        $sql="show tables";   

        $result=M()->query($sql);  

        foreach ($result as $k=>$v) {             

            $k++;                     

            $_sql="SHOW FULL COLUMNS FROM ".$v['tables_in_'.C('DB_NAME')]; 

            $data[][0]=array("表 {$k}.".$v['tables_in_'.C('DB_NAME')]."表",'','','','','','');

            $data[][1]=array("字段","类型","校对","NULL","键","默认","额外","权限","注释");

            $data[]=M()->query($_sql);  


            $data[][]=array();                      

        }          

        //导入PHPExcel类库         

        import("Common.Org.PHPExcel");        

        import("Common.Org.PHPExcel.Writer.Excel5");         

        import("Common.Org.PHPExcel.IOFactory.php");         

        $filename="test_excel";              

        $this->getExcel($filename,$data);    

    }  


    private function getExcel($fileName,$data){             

    //对数据进行检验            

         if(empty($data)||!is_array($data)){                 

             die("data must be a array");             

         }             

        $date=date("Y_m_d",time()); 

        $fileName.="_{$date}.xls";              

        //创建PHPExcel对象，注意，不能少了\             

        $objPHPExcel=new \PHPExcel();             

        $objProps=$objPHPExcel->getProperties();  


        $column=2;             

        $objActSheet=$objPHPExcel->getActiveSheet();   

        $objPHPExcel->getActiveSheet()->getStyle()->getFont()->setName('微软雅黑');//设置字体

        $objPHPExcel->getActiveSheet()->getDefaultRowDimension()->setRowHeight(25);//设置默认高度


        $objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth('5');//设置列宽

        $objPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth('22');//设置列宽

        $objPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth('22');//设置列宽

        $objPHPExcel->getActiveSheet()->getColumnDimension('J')->setWidth('40');//设置列宽


        //设置边框

        $sharedStyle1=new \PHPExcel_Style();

        $sharedStyle1->applyFromArray(array('borders'=>array('allborders'=>array('style'=>\PHPExcel_Style_Border::BORDER_THIN))));

        

        foreach ($data as $ke=>$row){      


            foreach($row as $key=>$rows){


                if(count($row)==1&&empty($row[0][1])&&empty($rows[1])&&!empty($rows)){


                    $objPHPExcel->getActiveSheet()->setSharedStyle($sharedStyle1, "A{$column}:J{$column}");//设置边框

                    array_unshift($rows,$rows['0']);

                    $objPHPExcel->getActiveSheet()->mergeCells("A{$column}:J{$column}");//合并单元格

                    $objPHPExcel->getActiveSheet()->getStyle("A{$column}:J{$column}")->getFont()->setSize(12);//字体

                    $objPHPExcel->getActiveSheet()->getStyle("A{$column}:J{$column}")->getFont()->setBold(true);//粗体


                    //背景色填充

                    $objPHPExcel->getActiveSheet()->getStyle("A{$column}:J{$column}")->getFill()->setFillType(\PHPExcel_Style_Fill::FILL_SOLID);

                    $objPHPExcel->getActiveSheet()->getStyle("A{$column}:J{$column}")->getFill()->getStartColor()->setARGB('FFB8CCE4');


                }else{

                    if(!empty($rows)){

                        array_unshift($rows,$key+1);

                        $objPHPExcel->getActiveSheet()->setSharedStyle($sharedStyle1,"A{$column}:J{$column}");//设置边框

                    } 

                }


                if($rows['1']=='字段'){

                    $rows[0]='ID';

                    //背景色填充

                    $objPHPExcel->getActiveSheet()->getStyle("A{$column}:J{$column}")->getFill()->setFillType(\PHPExcel_Style_Fill::FILL_SOLID);

                    $objPHPExcel->getActiveSheet()->getStyle("A{$column}:J{$column}")->getFill()->getStartColor()->setARGB('FF4F81BD');

                }


                $objPHPExcel->getActiveSheet()->getStyle("A{$column}:J{$column}")->getAlignment()->setVertical(\PHPExcel_Style_Alignment::VERTICAL_CENTER);//垂直居中

                $objPHPExcel->getActiveSheet()->getStyle("A{$column}:J{$column}")->getAlignment()->setWrapText(true);//换行

                 //行写入                     

                $span = ord("A");                       

                foreach($rows as $keyName=>$value){                    

                    // 列写入                       

                    $j=chr($span);                         

                    $objActSheet->setCellValue($j.$column, $value);                        

                    $span++;                     

                }                     

                $column++;                 

            }             

        } 

        $fileName = iconv("utf-8", "gb2312", $fileName);             

        //设置活动单指数到第一个表,所以Excel打开这是第一个表             

        $objPHPExcel->setActiveSheetIndex(0);             

        header('Content-Type: application/vnd.ms-excel');             

        header("Content-Disposition: attachment;filename=\"$fileName\"");             

        header('Cache-Control: max-age=0');                

        $objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');             

        $objWriter->save('php://output'); //文件通过浏览器下载             

        exit;
