本文主要和大家分享php如何用header导出excel详解，希望能帮助到大家，我们先来看一下示例图。

这个是导出execl 按钮

<button class="btn btn-success" type="button" id="execl"><i class="icon-search"></i>导出execl</button>
<script>
        $("#execl").click(function(){
           var  data = $("form").serialize();
            location.href = "<{:U('excel')}>?"+data;
        });
    </script>
直接把查询条件,全部传值给另外一个连接

lists 是查询的列表方法, excel 是导出方法, 把原来的方法调用一遍

添加 2个 header 代码然后改写 view html 的文件就直接导出了

function lists()
    {

        I("date") ? $this->date = I("date"):$this->date =date("Y-m");

        $where = $this->query();

        $model = M("project_sign");
        $model->join("JOIN  __PROJECT_USER__ on s_user_id = pu_id");
        $model->join("JOIN  __PROJECT_TEAM__ on s_team_id = t_id");
        $model->join("JOIN  __PROJECT__ on s_project_id = p_id");
        $model->order("s_id desc");
        $results = $model->where($where)->select();

        $res = array();
        foreach($results as $value)
        {
            if(!isset($res[$value['s_user_id']]['info']))
            {
                $res[$value['s_user_id']]['info'] = $value;
            }
            if(!isset($res[$value['s_user_id']]['sign']))
            {
                $res[$value['s_user_id']]['sign'] = array_pad(array(),32,"");
                unset($res[$value['s_user_id']]['sign'][0]);
            }

            $res[$value['s_user_id']]['sign'][$value['s_day']] = "是";
            $res[$value['s_user_id']]['count']++;
        }

        $this->results = $res;
        $this->display();
    }


    function excel()
    {
        header("Content-type: application/vnd.ms-excel; charset=utf8");
        header("Content-Disposition: attachment; filename=filename.xls");
        $this->lists();
    }

由于导出的excel 不用css 所以直接写一个纯表格的view

<html>
<head>
    <meta charset="utf-8">
</head>
<body>
<table border="1" class="table table-border table-bordered table-hover table-bg">
            <tr class="text-c"  >
                <th rowspan="2" >编号</th>
                <th rowspan="2">姓名</th>
                <th rowspan="2">工种</th>
                <th colspan="31"><{$date}></th>
                <th rowspan="2">合计</th>
            </tr>
             <volist name="results" id="value" key="key">
                 <tr   class="text-c">
                    <td>1</td>
                    <td>2</td>
                    <td>3</td>
                    <td>4</td>
                    <td>5</td>
                    <td>6</td>
                    <td>7</td>
                    <td>8</td>
                    <td>9</td>
                    <td>10</td>
                    <td>11</td>
                    <td>12</td>
                    <td>13</td>
                    <td>14</td>
                    <td>15</td>
                    <td>16</td>
                    <td>17</td>
                    <td>18</td>
                    <td>19</td>
                    <td>20</td>
                    <td>21</td>
                    <td>22</td>
                    <td>23</td>
                    <td>24</td>
                    <td>25</td>
                    <td>26</td>
                    <td>27</td>
                    <td>28</td>
                    <td>29</td>
                    <td>30</td>
                    <td>31</td>
                </tr>
                <tr class="text-c">
                    <td><{$key}></td>
                    <td><{$value.info.pu_name}></td>
                    <td><{$value.info.t_name}></td>
                    <volist name="value.sign" id="v">
                        <td><{$v}></td>
                    </volist>
                    <td><{$value.count}></td>
                </tr>

            </volist>
        </table>
</body>
