一：先获取数据

<!--more-->

public function output($dataResult=array()){
    $headTitle = date('YmdHis');
    $title = date('YmdHis');
    $headtitle= "{$headTitle}";
    $titlename = '';
    $headtitle = "
ID
           条码号
           商品组合
           项目明细
           病人
           医生姓名
           医生折扣
           代理姓名
           业务员
           原价
           实付
           退款
           日期
       ";
    $filename = $title.".xls";
    $this->excelData($dataResult,$titlename,$headtitle,$filename);
}

二：输出

    /*
 *处理Excel导出
 *@param $datas array 设置表格数据
 *@param $titlename string 设置head
 *@param $title string 设置表头
 */
private function excelData($datas,$titlename,$title,$filename){
    $str = "rnrnrnrn";
    $str .="".$titlename."";
    $str .= $title;
    foreach ($datas  as $key=> $rt )
    {
        $str .= "";
        foreach ( $rt as $k => $v )
        {
            $str .= "";
        }
        $str .= "n";
    }
    $str .= "

＇{$v}
";
    header("Content-type:application/vnd.ms-excel");
    //header( "Content-Type: application/vnd.ms-excel; name='excel'" );
    //header( "Content-type: application/octet-stream" );
    header( "Content-Disposition: attachment; filename=".$filename );
    //header( "Cache-Control: must-revalidate, post-check=0, pre-check=0" );
    header( "Pragma: no-cache" );
    header( "Expires: 0" );
    exit( $str );
}
