PHP Foreach嵌套循环和阵列本身在中间重置

Question

我有这个PHP代码，3 foreach循环和最后一个或可能是第二个导致数组重置在某些时候，我找不到原因？

PHP代码：

<?php 
    $months = range(1,12); 
    foreach($accountsubs as $subs){ 
     ?> 
    <tr style="display:none;" class="tablerow paddingzero childoverview <?php echo $classj;?>"> 
    <td width="40" align="center"><?php echo $subs['codename'];?></td> 
    <td><?php echo $subs['subclass'];?></td> 
    <?php 
    $itemcodes = $db->fetch_all_array("SELECT * FROM bg_itemcodes WHERE accountclass='".$subs['ID']."' and cparent = '".$ac['ID']."' "); 
    $counter = 1; 
    foreach($itemcodes as $code){ 

     foreach($months as $ms){ 
echo $counter++; 
      $makedate = strtotime($jdate.'-'.$ms.'-1'); 
      $sdebits = $db->single("SELECT sum($currency) as $currency FROM bg_journal WHERE factory='$jfactory' 
      AND section = '".$ac['ID']."' AND record_section !='record' AND itemcode = '".$code['ID']."' 
      AND FROM_UNIXTIME(jtime, '%Y%m') = '".date('Ym',$makedate)."' AND inouts = 'out' "); 


      $scredits = $db->single("SELECT sum($currency) as $currency FROM bg_journal WHERE factory='$jfactory' 
      AND section = '".$ac['ID']."' AND record_section !='record' AND itemcode = '".$code['ID']."' 
      AND FROM_UNIXTIME(jtime, '%Y%m') = '".date('Ym',$makedate)."' AND inouts = 'in' "); 


      $totalsdc = $scredits[$currency] - $sdebits[$currency]; 
     ?> 
    <td class="alignright"><?php echo correctvalue($totalsdc,$jcurrency);?></td> 
    <?php 
     }// foreach months 
    }// foreach item codes 
    ?> 
    </tr> 
    <?php 

    }// foreach sub class 

，这里是你可以看到它是如何重置3日环路但是它避开了在第二循环计数器观看源。

Answer 1

有没有这样的事情是发生在这里阵列复位。如果你检查你的代码，那么你可以清楚地看到变量$counter在项目代码之前被初始化/重新初始化。因此，合乎逻辑的解释是子类别Raw Materials为该查询返回两个对象：

$itemcodes = $db->fetch_all_array("SELECT * FROM bg_itemcodes WHERE accountclass='".$subs['ID']."' and cparent = '".$ac['ID']."' "); 

即，您得到2 * 12的时间增量为$counter，等于24.

您可能希望按项目代码将每项费用分组，以及为子类别进行分组。
