thinkphp 3.2与phpexcel

thinkphp版本：3.2

1.在http://phpexcel.codeplex.com/下载最新PHPExcel

2.把Classes目录下的文件（PHPExcel.php和PHPExcel文件夹）放到ThinkPHP\Library\Org\Util目录下；并且把PHPExcel.phpg改名为PHPExcel.class.php

3.导出数据

第一种方案【单一完整版】：

public function ff(){
        //导入PHPExcel类库，因为PHPExcel没有用命名空间，只能inport导入
        import("Org.Util.PHPExcel");

        //创建PHPExcel对象，注意，不能少了\
        $objPHPExcel = new \PHPExcel();
        $objProps = $objPHPExcel->getProperties();

        //设置表头
        $key = ord("A");
        foreach($headArr as $v){
            $colum = chr($key);
            $objPHPExcel->setActiveSheetIndex() ->setCellValue($colum.'', $v);
            $key += ;
        }

        $column = ;
        $objActSheet = $objPHPExcel->getActiveSheet();

        $date = date("Y_m_d",time());
        $fileName .= "_{$date}.xls";

        $data=array(
            array('username'=>'wangwu','password'=>"http://www.thinkphp.cn/Public/new/img/header_logo.png"),
            );

        foreach($data as $key => $rows){ //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);
        //重命名表
        // $objPHPExcel->getActiveSheet()->setTitle('test');
        //设置活动单指数到第一个表,所以Excel打开这是第一个表
        $objPHPExcel->setActiveSheetIndex();
        header('Content-Type: application/vnd.ms-excel');
        header("Content-Disposition: attachment;filename=\"$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

    }

第二种方案【分开完整版】：

public function out(){
        $data=array(
            array('username'=>'zhangsan','password'=>""),
            array('username'=>'lisi','password'=>"abcdefg"),
            array('username'=>'wangwu','password'=>""),
            );
        //导入PHPExcel类库，因为PHPExcel没有用命名空间，只能inport导入
        import("Org.Util.PHPExcel");
        import("Org.Util.PHPExcel.Writer.Excel5");
        import("Org.Util.PHPExcel.IOFactory.php");

        $filename="test_excel";
        $headArr=array("用户名","密码");
        $this->getExcel($filename,$headArr,$data);
    }

    private    function getExcel($fileName,$headArr,$data){
            //对数据进行检验
            if(empty($data) || !is_array($data)){
                die("data must be a array");
            }
            //检查文件名
            if(empty($fileName)){
                exit;
            }

            $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
            $key = ord("A");
            foreach($headArr as $v){
                $colum = chr($key);
                $objPHPExcel->setActiveSheetIndex() ->setCellValue($colum.'', $v);
                $key += ;
            }

            $column = ;
            $objActSheet = $objPHPExcel->getActiveSheet();
            foreach($data as $key => $rows){ //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);
            //重命名表
               // $objPHPExcel->getActiveSheet()->setTitle('test');
            //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();

            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;
        }
