PHP导出报表(案例)

需求

为了实现报表效果，自己杜撰的需求。

主要是思路，思路通了实现其他效果也OK。

统计每个人在一年中每一天迟到早退的情况。

思路

用 PHP 语言进行实现。

首先将报表样式用 HTML 实现，

然后利用PHP header 函数生成 xls 下载。

知识点

表格中的列合并与行合并
PHP 获取一年中的每一天进行展示
PHP header 函数
Smarty 模板函数
Smarty 自定义函数
...

PHP 代码

public function export()
{

    //获取2016年日期
    $time_start = strtotime('2016-01-01');
    $time_end   = strtotime('2016-12-31');

    $month_arr = [];
    $month_arr['month'][]   = '2016-01';
    $month_arr['numbers'][] = date(t,$time_start); //获取天数

    while (($time_start = strtotime('+1 month', $time_start)) <= $time_end) {
        $month_arr['month'][]   = date('Y-m',$time_start); //取得递增月
        $month_arr['numbers'][] = date(t,$time_start);     //获取天数
    }

    function check_week($time = [])
    {
        if (empty($time['day'])) {
            return '';
        }
        $w = intval(date('w' , strtotime($time['day'])));
        if( $w === 0 || $w === 6){
            return '<td style="background-color: red;">'.date('d', strtotime($time['day'])).'</td>';
        }
        return '<td>'.date('d', strtotime($time['day'])).'</td>';
    }

    //向模板中注册一个函数
    $this->smarty->registerPlugin('function','check_week','check_week');

    //模拟数据如下：
