PHP 统计数据功能 有感

统计，就是把基本的数据，整合起来。

用到sql的，有group by 功能，count功能，order by功能等等。

sql将收集的数据，进行统计分析。

一般情况下，sql处理后得到的数据，还要通过php的逻辑来进行整理。

以一定的格式，展示到前台。

一般都是以数组的方式展示，这也是数据结构的概念。

看这张图片，基本想想结构大概为

{上线数，出单总数，核过总数，总人均，总核率，{(坐席人1，工号1，出单数1，发货数1，核单率1),(坐席人2，工号2，出单数2，发货数2，核单率2)}}

如果用php展示成上面的结构的话，就很好处理了。

首先通过sql获取初次处理的数据，

别小看这初次处理的数据，处理的好，会非常的便捷。

SELECT a.user,count(order_id) as subcount,b.passcount,c.full_name from vicidial_order a LEFT JOIN (SELECT user,count(order_id) as passcount from vicidial_order where time > UNIX_TIMESTAMP('2015-11-7') and user_group = 'TeamOne' and verifysta = 'Y' GROUP BY user ) b on a.user = b.user LEFT JOIN vicidial_users c on a.user = c.user where time > UNIX_TIMESTAMP('2015-11-7') and a.user_group = 'TeamOne' GROUP BY a.user ;

sql思路，归类订单表，以user来进行归类。

获取每个人，当天的订单提交总数count()。

还要获取每个人，订单通过审核的总数，通过where筛选。

然后关联查询其他相关数据。

有了这些基本数据，其他的相关数据都能出来了。

通过php来处理获取，其中变量命名要清晰，这样也有利于阅读代码。

$select_sql = "SELECT a.user,count(order_id) as subcount,b.passcount,c.full_name from vicidial_order a LEFT JOIN (SELECT user,count(order_id) as passcount from vicidial_order where time > UNIX_TIMESTAMP('".$today."') and user_group = '".$user_group."' and verifysta = 'Y' GROUP BY user ) b on a.user = b.user LEFT JOIN vicidial_users c on a.user = c.user where time > UNIX_TIMESTAMP('".$today."') and a.user_group = '".$user_group."' GROUP BY a.user ";
        $rows = mysqli_query( $db_conn, $select_sql );
        $row_counts_list = mysqli_num_rows( $rows );
        if ( $row_counts_list !=  )
        {
            $i = ;
            while($rs = mysqli_fetch_assoc( $rows )) // mysqli_fetch_assoc 获取键值数据     mysqli_fetch_field 获取一条数据 mysqli_fetch_fields 获取多组数据    mysqli_fetch_row
            {
                $outData['list'][$i]['user'] = $rs['user'];
                $outData['list'][$i]['full_name'] = $rs['full_name'];
                $outData['list'][$i]['subcount'] = $rs['subcount'];
                $outData['list'][$i]['passcount'] = $rs['passcount'];
                $outData['list'][$i]['passrate'] = round(($rs['passcount']/$rs['subcount'])*)."%";

                $outData['all_subcount'] += $rs['subcount'];
                $outData['all_passcount'] += $rs['passcount'];

                $i++;
            }
            $outData['all_passrate'] = round(($outData['all_passcount']/$outData['all_subcount'])*)."%";
            $outData['online_count'] = $row_counts_list;
            $outData['average_subcount'] = round($outData['all_subcount']/$outData['online_count'],);
        }

其中outData就是要输出的数据结构类型。

Array
(
    [list] => Array
        (
            [] => Array
                (
                    [user] =>
                    [full_name] => 魏硕磊
                    [subcount] =>
                    [passcount] =>
                    [passrate] => %
                )

            [] => Array
                (
                    [user] =>
                    [full_name] => 刘庆
                    [subcount] =>
                    [passcount] =>
                    [passrate] => %
                )

            [] => Array
                (
                    [user] =>
                    [full_name] => 章厚英
                    [subcount] =>
                    [passcount] =>
                    [passrate] => %
                )

        )

    [all_subcount] =>
    [all_passcount] =>
    [all_passrate] => %
    [online_count] =>
    [average_subcount] =>
)

获取数据后，一切都好办了。

套入页面就可以了，然后自己再调试调试。
