thinkphp3.2结合PHPExcel导出数据库里所有表的结构,含注释
先看图

一、控制器代码如下：

    public function out(){

        $sql="show tables";//读取库里所有的表


        $result=M()->query($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_test']} 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("Org.Util.PHPExcel");

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

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


        $filename="test_excel";

        $headArr=array("ID","字段","类型","NULL","键","默认","额外","注释");

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

    }



    private    function getExcel($fileName,$headArr,$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();

            

            //设置表头

            $key = ord("A");

            $column = 2;

            $objActSheet = $objPHPExcel->getActiveSheet();


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

                foreach($row as $key => $rows){ //行写入

                    $span = ord("B");

                    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;

    }
