PHP Foreach嵌套循環和陣列本身在中間重置

Question

我有這個PHP代碼，3 foreach循環和最後一個或可能是第二個導致數組重置在某些時候，我找不到原因？

PHP代碼：

<?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 

，這裏是你可以看到它是如何重置3日環路但是它避開了在第二循環計數器觀看源。

Answer 1

有沒有這樣的事情是發生在這裏陣列復位。如果你檢查你的代碼，那麼你可以清楚地看到變量$counter在項目代碼之前被初始化/重新初始化。因此，合乎邏輯的解釋是子類別Raw Materials爲該查詢返回兩個對象：

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

即，您得到2 * 12的時間增量爲$counter，等於24.

您可能希望按項目代碼將每項費用分組，以及爲子類別進行分組。
