本文實(shí)例講述了PHP實(shí)現(xiàn)的統(tǒng)計(jì)數(shù)據(jù)功能。分享給大家供大家參考，具體如下：

統(tǒng)計(jì)，就是把基本的數(shù)據(jù)，整合起來。

用到sql的，有g(shù)roup by 功能，count功能，order by功能等等。

sql將收集的數(shù)據(jù)，進(jìn)行統(tǒng)計(jì)分析。

一般情況下，sql處理后得到的數(shù)據(jù)，還要通過php的邏輯來進(jìn)行整理。

以一定的格式，展示到前臺。（推薦學(xué)習(xí)：PHP編程從入門到精通）

一般都是以數(shù)組的方式展示，這也是數(shù)據(jù)結(jié)構(gòu)的概念。

看這張圖片，基本想想結(jié)構(gòu)大概為

{上線數(shù)，出單總數(shù)，核過總數(shù)，總?cè)司?，總核率，{(坐席人1，工號1，出單數(shù)1，發(fā)貨數(shù)1，核單率1),(坐席人2，工號2，出單數(shù)2，發(fā)貨數(shù)2，核單率2)}}

如果用php展示成上面的結(jié)構(gòu)的話，就很好處理了。

首先通過sql獲取初次處理的數(shù)據(jù)，

別小看這初次處理的數(shù)據(jù)，處理的好，會非常的便捷。

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，歸類訂單表，以user來進(jìn)行歸類。

獲取每個(gè)人，當(dāng)天的訂單提交總數(shù)count()。

還要獲取每個(gè)人，訂單通過審核的總數(shù)，通過where篩選。

然后關(guān)聯(lián)查詢其他相關(guān)數(shù)據(jù)。

有了這些基本數(shù)據(jù)，其他的相關(guān)數(shù)據(jù)都能出來了。

通過php來處理獲取，其中變量命名要清晰，這樣也有利于閱讀代碼。

$select_sql = "SELECT a.user,count(order_id) as subcount,b.passcount,c.full_name from vicidial_order a LEFT  JOIN (SELECT user,count(order_id) as passcount from vicidial_order where time > UNIX_TIMESTAMP('".$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 獲取鍵值數(shù)據(jù)   mysqli_fetch_field 獲取一條數(shù)據(jù) mysqli_fetch_fields 獲取多組數(shù)據(jù)  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); }
