我正在使用 PHP 5.6 和 7.0.29 执行以下 SQLSRV 查询，当我得到结果时，我似乎无法使用 array_sum 添加（SUM）“grand_total”的总结果，甚至当我尝试循环它时。

$sql = "SELECT inv_trx.trx_date, datepart(day, datediff(day, 0, inv_trx.trx_date)/7 * 7)/7 + 1 AS WEEKNUMBER ,  DATEPART(WEEK, DATEADD(MM, DATEDIFF(MM,0,'".$datetime."'), 0))+ 1 AS WEEK_OF_MONTH,   inv_trx.trx_qty, inv_trx.unit_price, inv_trx.ord_qty, item.prod_cat, inv_trx.slsman_1, SUM(inv_trx.trx_qty * inv_trx.unit_price) AS grand_total

FROM dbo.customer customer, dbo.inv_trx inv_trx, dbo.item item, dbo.ord_hedr  ord_hedr

WHERE  datepart(day, datediff(day, 0, inv_trx.trx_date)/7 * 7)/7 + 1 = '1' AND customer.cust_no = inv_trx.cust_no AND customer.cust_no = ord_hedr.cust_no AND inv_trx.order_no = ord_hedr.order_no AND inv_trx.item_no = item.item_no AND 
inv_trx.manu_no = item.manu_no AND ((ord_hedr.ord_type='O') AND (inv_trx.trx_type='S') AND (ord_hedr.ord_class<>'M' And ord_hedr.ord_class<>'P') AND (customer.exclude_sa=0) OR (ord_hedr.ord_type='C') AND (inv_trx.trx_type='S') AND (ord_hedr.ord_class<>'M' And ord_hedr.ord_class<>'P') AND (customer.exclude_sa=0)) AND YEAR(inv_trx.trx_date) = '2018' AND MONTH(inv_trx.trx_date) = '7' GROUP BY  inv_trx.trx_date, DATEPART(WEEK,inv_trx.trx_date), inv_trx.trx_qty, inv_trx.unit_price, inv_trx.ord_qty, item.prod_cat, inv_trx.slsman_1  ";

$params = array();
$result = sqlsrv_query( $conn, $sql );
if( $result === false) {
    die( print_r( sqlsrv_errors(), true) ); 
}

while( $row = sqlsrv_fetch_array($result, SQLSRV_FETCH_ASSOC) ) {



 ?>  <tr>
                    <td><?php echo $row['trx_date']->format('m/d/Y')?></td>
                    <td><?php echo $row['WEEKNUMBER']?></td>
                    <td><?php echo $row['trx_qty']?></td>
                    <td><?php echo $row['unit_price']?></td>
                    <td><?php echo $row['ord_qty']?></td>
                    <td><?php echo $row['prod_cat']?></td>
                    <td><?php echo $row['slsman_1']?></td>
                    <td><?php echo $row['grand_total']?></td>
                </tr> 
                 <?php

                  $group = array($row['grand_total']);
                   print_r(array_sum($group));
                  //echo $row['grand_total']; //result is the same

Array_sum 的结果是相同的，只是与 grand_total 本身相呼应。

示例：4.8 6 109.4 1.197 17.8 45.5 89 而不是总计 = 184.XX

这是因为我已经使用 SUM 来总计 inv_trx.trx_qty * inv_trx.unit_price 来形成 grand_total？

我怀疑这是我的阵列的问题，但我不确定。任何建议将不胜感激。

查询产生以下

Trx Date    Week    Trx QTY Price   Quantity    Category    Salesman    Total
09/02/2018  1         1   4.8        80          MAG          Mickey        4.8
09/02/2018  1         3    2         50          BOB          Donald         6
09/02/2018  1         4    27.35      4         POW           Goose       109.4

我想做的是得到总和，即grand_total。

这对于评论来说太长了，并且没有回答您目前正在努力的部分，但是您可以使用别名、正确的连接语法和一些格式来大大简化您的整个查询。

SELECT it.trx_date
    , datepart(day, datediff(day, 0, it.trx_date) / 7 * 7) / 7 + 1 AS WEEKNUMBER 
    , DATEPART(WEEK, DATEADD(month, DATEDIFF(month, 0, '".$datetime."'), 0)) + 1 AS WEEK_OF_MONTH
    , it.trx_qty
    , it.unit_price
    , it.ord_qty
    , i.prod_cat
    , it.slsman_1
    , SUM(it.trx_qty * it.unit_price) AS grand_total
FROM dbo.customer c
join dbo.inv_trx it on c.cust_no = it.cust_no 
join dbo.item i on it.item_no = i.item_no 
                    AND it.manu_no = i.manu_no 
join dbo.ord_hedr oh on c.cust_no = oh.cust_no
                    AND it.order_no = oh.order_no 
WHERE  datepart(day, datediff(day, 0, it.trx_date) / 7 * 7) / 7 + 1 = 1
    AND oh.ord_type in ('O', 'C')
    AND it.trx_type = 'S'
    AND oh.ord_class not in ('M', 'P')
    AND c.exclude_sa = 0 
    AND YEAR(it.trx_date) = 2018 --date functions return integers not strings
    AND MONTH(it.trx_date) = 7 
GROUP BY it.trx_date
    , DATEPART(WEEK, it.trx_date)
    , it.trx_qty
    , it.unit_price
    , it.ord_qty
    , i.prod_cat
    , it.slsman_1

添加 GROUPING SETS 的示例。

我会看一下这篇文章，以很好地解释它是如何工作的。

SELECT it.trx_date
    , datepart(day, datediff(day, 0, it.trx_date) / 7 * 7) / 7 + 1 AS WEEKNUMBER 
    , DATEPART(WEEK, DATEADD(month, DATEDIFF(month, 0, '".$datetime."'), 0)) + 1 AS WEEK_OF_MONTH
    , it.trx_qty
    , it.unit_price
    , it.ord_qty
    , i.prod_cat
    , it.slsman_1
    , SUM(it.trx_qty * it.unit_price) AS grand_total
FROM dbo.customer c
join dbo.inv_trx it on c.cust_no = it.cust_no 
join dbo.item i on it.item_no = i.item_no 
                    AND it.manu_no = i.manu_no 
join dbo.ord_hedr oh on c.cust_no = oh.cust_no
                    AND it.order_no = oh.order_no 
WHERE  datepart(day, datediff(day, 0, it.trx_date) / 7 * 7) / 7 + 1 = 1
    AND oh.ord_type in ('O', 'C')
    AND it.trx_type = 'S'
    AND oh.ord_class not in ('M', 'P')
    AND c.exclude_sa = 0 
    AND YEAR(it.trx_date) = 2018 --date functions return integers not strings
    AND MONTH(it.trx_date) = 7 
GROUP BY GROUPING SETS((it.trx_date
    , DATEPART(WEEK, it.trx_date)
    , it.trx_qty
    , it.unit_price
    , it.ord_qty
    , i.prod_cat
    , it.slsman_1), ())

如果您的 T-SQL 语句返回行并且您想对结果集中每一行的值求和，则需要在之前定义数组while () {...}，然后添加每一行的值：

<?php
...

# Statement
$sql = ' ... your statement ...';
$params = array();
$result = sqlsrv_query($conn, $sql, $params);
if ($result === false) {
    die( print_r(sqlsrv_errors(), true)); 
}

# Results
$total = array();
while ($row = sqlsrv_fetch_array($result, SQLSRV_FETCH_ASSOC)) {
?>  
    <tr>
    <td><?php echo $row['trx_date']->format('m/d/Y')?></td>
    <td><?php echo $row['WEEKNUMBER']?></td>
    <td><?php echo $row['trx_qty']?></td>
    <td><?php echo $row['unit_price']?></td>
    <td><?php echo $row['ord_qty']?></td>
    <td><?php echo $row['prod_cat']?></td>
    <td><?php echo $row['slsman_1']?></td>
    <td><?php echo $row['grand_total']?></td>
    </tr>
<?php
    $total[] = $row['grand_total'];
    echo 'Grand total after current row: '.array_sum($total).'<br>';
}   

# Total after all rows
echo 'Grand total after all rows: '.array_sum($total).'<br>';

...
?>
