PHP实现的统计数据功能详解

本文实例讲述了PHP实现的统计数据功能。分享给大家供大家参考，具体如下：

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 != 0 )
{
  $i = 0;
  while($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'])*100)."%";
    $outData['all_subcount'] += $rs['subcount'];
    $outData['all_passcount'] += $rs['passcount'];
    $i++;
  }
  $outData['all_passrate'] = round(($outData['all_passcount']/$outData['all_subcount'])*100)."%";
  $outData['online_count'] = $row_counts_list;
  $outData['average_subcount'] = round($outData['all_subcount']/$outData['online_count'],1);
}

其中outData就是要输出的数据结构类型。

Array
(
  [list] => Array
    (
      [0] => Array
        (
          [user] => 8001
          [full_name] => 魏硕磊
          [subcount] => 3
          [passcount] => 2
          [passrate] => 67%
        )
      [1] => Array
        (
          [user] => 8004
          [full_name] => 刘庆
          [subcount] => 2
          [passcount] => 2
          [passrate] => 100%
        )
      [2] => Array
        (
          [user] => 8005
          [full_name] => 章厚英
          [subcount] => 4
          [passcount] => 3
          [passrate] => 75%
        )
    )
  [all_subcount] => 9
  [all_passcount] => 7
  [all_passrate] => 78%
  [online_count] => 3
  [average_subcount] => 3
)

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。
