php中变量的使用问题
从数据库中获得了各区的销售金额和销售数量,要对数量和金额求和。代码如下:
<br />
<?PHP<br />
<br />
ob_start();<br />
require_once 'DB.php';<br />
ob_end_clean();<br />
$db=DB::Connect();<br />
$result=$db->QueryLastMonth();<br />
$result1=$db->QueryLastMonthByArea();<br />
$all_sales_amount;<br />
$all_sales_money;<br />
echo 'begin '.$all_sales_amount;<br />
while($row1= sybase_fetch_assoc($result1))<br />
{<br />
?><br />
<tr><br />
<th data-options="field:'itemid',width:80"><?php <br />
switch($row1["areacode"]){<br />
case "E":<br />
echo "华东区";<br />
break;<br />
case "C":<br />
echo "东北区";<br />
break;<br />
case "N":<br />
echo "华北区";<br />
break;<br />
case "W":<br />
echo "西大区(W)";<br />
break;<br />
case "H":<br />
echo "华中区";<br />
break;<br />
case "S":<br />
echo "华南区";<br />
break;<br />
case "F":<br />
echo "华东区(经销)";<br />
break;<br />
case "T":<br />
echo "西大区(T)";<br />
break;<br />
}<br />
?></th><br />
<th data-options="field:'productid',width:80"><?php echo $row1["area_salesgoodssum"]?></th><br />
<th data-options="field:'listprice',width:100,align:'right'"><?php echo $row1["area_salesmoneysum"]?></th><br />
<th data-options="field:'unitcost',width:80,align:'right'">--</th><br />
<th data-options="field:'status',width:60,align:'center'">--</th><br />
</tr><br />
<br />
<?php <br />
$all_sales_amount+=$row1["area_salesgoodssum"];<br />
$all_sales_money+=$row1["area_salesmoney"];<br />
echo '循环中数量'.$all_sales_amount."金额".$all_sales_money."<br>";<br />
}<br />
?><br />
</thead><br />
</table><br />
</div><br />
<br />
<br />
<div class="easyui-draggable" data-options="handle:'#title'" style="width:220px;height:160px;background:#fafafa;border:1px solid #ccc;margin-top:10px"><br />
<div id="title" style="padding:5px;background:#ccc;color:#FA0000">销售简报<?php ?></div><br />
<span>总金额:<?php echo $all_sales_money; ?> </span><br><br />
<span>总数量:<?php echo $all_sales_amount?> </span><br />
