创建正确的数组摘要

Question

我正在创建一个脚本以创建项目摘要。唯一看起来没有正常工作的是项目汇总金额。也就是说，这些三线的价格，而不是和显示的最后一个值：

echo "<td><strong>" . number_format($summary['counterExtended'], 2) . "</strong></td>"; 
echo "<td><strong>" . number_format($summary['onlineExtended'], 2) . "</strong></td>"; 
echo "<td><strong>" . number_format($summary['voucherExtended'], 2) . "</strong></td>"; 

即使我已经在这里被加入其中：

if (true === isset($lineItems[$category][$description])) { 

    $data     = $lineItems[$category][$description]; 
    $data['quantity']  += $qty; 
    $data['counterExtended'] += $counterExtended; 
    $data['onlineExtended'] += $onlineExtended; 
    $data['voucherExtended'] += $voucherExtended; 

    $lineItems[$category][$description] = $data; 

    $categoryTotals[$category]['counterExtended'] += $counterExtended; 
    $categoryTotals[$category]['onlineExtended'] += $onlineExtended; 
    $categoryTotals[$category]['voucherExtended'] += $voucherExtended; 

我会注意到，数量增加只要不是$ counterExtended，$ onlineExtended，$ voucherExtended。它们只显示最后一个值，而不是每个月为每个项目添加所有值。

这里是SQL循环：

$s->bind_result($id, $qty, $price, $online, $voucher, $month, $year, $description, $cat, $category); 

    $lineItems  = array(); 
    $categoryTotals = array(); 

    while($s->fetch()) { 

      if ($online == 0 && $voucher == 0) { 
       $counterExtended = $qty * $price; 
       $onlineExtended = 0; 
       $voucherExtended = 0; 
      } 

      if ($online == 1) { 
       $counterExtended = 0; 
       $onlineExtended = $qty * $price; 
       $voucherExtended = 0; 
      } 

      if ($voucher == 1) { 
       $counterExtended = 0; 
       $onlineExtended = 0; 
       $voucherExtended = $qty * $price; 
      } 

     // Repeated item, increment values accordingly 
     if (true === isset($lineItems[$category][$description])) { 

      $data     = $lineItems[$category][$description]; 
      $data['quantity']  += $qty; 
      $data['counterExtended'] += $counterExtended; 
      $data['onlineExtended'] += $onlineExtended; 
      $data['voucherExtended'] += $voucherExtended; 

      $lineItems[$category][$description] = $data; 

      $categoryTotals[$category]['counterExtended'] += $counterExtended; 
      $categoryTotals[$category]['onlineExtended'] += $onlineExtended; 
      $categoryTotals[$category]['voucherExtended'] += $voucherExtended; 

     // First time hitting an item with this description 
     } else { 

      $lineItems[$category][$description] = array(
       'category'  => $category, 
       'description'  => $description, 
       'id'    => $id, 
       'counterExtended' => $counterExtended, 
       'onlineExtended' => $onlineExtended, 
       'voucherExtended' => $voucherExtended, 
       'quantity'  => $qty, 
       'year'   => $year, 
      ); 

      $categoryTotals[$category] = array(
       'counterExtended' => $counterExtended, 
       'onlineExtended' => $onlineExtended, 
       'voucherExtended' => $voucherExtended, 
      ); 
     } 

    } 

    // Now loop through the $lineItems array and output rows. 
    foreach ($categoryTotals as $category => $summary) { 

     while ($item = array_shift($lineItems[$category])) { 
      echo "<tr>"; 
      echo '<td>'.$item['year'].'</td>'; 
      echo '<td>'.$item['id'].'</td>'; 
      echo '<td>'.$item['quantity'].'</td>'; 
      echo "<td></td>"; 
      echo "<td>" . number_format($item['counterExtended'],2) . "</td>"; 
      echo "<td>" . number_format($item['onlineExtended'],2) . "</td>"; 
      echo "<td>" . number_format($item['voucherExtended'],2) . "</td>"; 
      echo '<td>'.$item['description'].'</td>'; 
      echo '<td>'.$item['category'].'</td>'; 
      echo "</tr>\n"; 
     } 

     echo "<tr>"; 
     echo "<td colspan=4></td>"; 
     echo "<td><strong>" . number_format($summary['counterExtended'], 2) . "</strong></td>"; 
     echo "<td><strong>" . number_format($summary['onlineExtended'], 2) . "</strong></td>"; 
     echo "<td><strong>" . number_format($summary['voucherExtended'], 2) . "</strong></td>"; 
     echo "<td><strong>$category</strong>"; 
     echo "<td></td>"; 
     echo "</tr>"; 

    } 


     $counterGrand=$counterGrand+$counterCat; 
     $onlineGrand=$onlineGrand+$onlineCat; 
     $voucherGrand=$voucherGrand+$voucherCat; 

Answer 1

在一个现有$category遇到一个新的$description每一次，从当前行，这抹了该类别的运行总计重新初始化$categoryTotals[$category]。您应该只在初次看到该类别时初始化此条目。

while ($s->fetch()) { 
    if (!isset($categoryTotals[$category])) { 
     $categoryTotals[$category] = array('counterExtended' => 0, 'onlineExtended' => 0, 'voucherExtended' => 0); 
     $lineItems[$category] = array(); 
    } 
    if (!isset($lineItems[$category][$description])) { 
     $lineItems[$category][$description] = array('quantity' => 0, 'counterExtended' => 0, 'onlineExtended' => 0, 'voucherExtended' => 0); 
    } 
    $data     =& $lineItems[$category][$description]; // Use reference so we don't make a copy that we have to assign back 
    $data['quantity']  += $qty; 
    $data['counterExtended'] += $counterExtended; 
    $data['onlineExtended'] += $onlineExtended; 
    $data['voucherExtended'] += $voucherExtended; 

    $categoryTotals[$category]['counterExtended'] += $counterExtended; 
    $categoryTotals[$category]['onlineExtended'] += $onlineExtended; 
    $categoryTotals[$category]['voucherExtended'] += $voucherExtended; 
} 

Answer 2

谢谢巴尔玛。我不得不做出一些改变，这是我最后的代码：

while($s->fetch()) { 

      if ($online == 0 && $voucher == 0) { 
       $counterExtended = $qty * $price; 
       $onlineExtended = 0; 
       $voucherExtended = 0; 
      } 

      if ($online == 1) { 
       $counterExtended = 0; 
       $onlineExtended = $qty * $price; 
       $voucherExtended = 0; 
      } 

      if ($voucher == 1) { 
       $counterExtended = 0; 
       $onlineExtended = 0; 
       $voucherExtended = $qty * $price; 
      } 

     // Repeated item, increment values accordingly 

    if (!isset($categoryTotals[$category])) { 
     $categoryTotals[$category] = array('counterExtended' => 0, 'onlineExtended' => 0, 'voucherExtended' => 0); 
     $lineItems[$category] = array(); 
    } 
    if (!isset($lineItems[$category][$description])) { 
     $lineItems[$category][$description] = array('quantity' => 0, 'counterExtended' => 0, 'onlineExtended' => 0, 'voucherExtended' => 0); 
    } 
    $data     =& $lineItems[$category][$description]; // Use reference so we don't make a copy that we have to assign back 
    $data['quantity']  += $qty; 
    $data['counterExtended'] += $counterExtended; 
    $data['onlineExtended'] += $onlineExtended; 
    $data['voucherExtended'] += $voucherExtended; 
    $data['description']  = $description; 
    $data['year']   = $year; 
    $data['id']    = $id; 



    $categoryTotals[$category]['counterExtended'] += $counterExtended; 
    $categoryTotals[$category]['onlineExtended'] += $onlineExtended; 
    $categoryTotals[$category]['voucherExtended'] += $voucherExtended; 


     // First time hitting an item with this description 


    } 

    // Now loop through the $lineItems array and output rows. 
    foreach ($categoryTotals as $category => $summary) { 

     while ($item = array_shift($lineItems[$category])) { 
      echo "<tr>"; 
      echo '<td>'.$item['year'].'</td>'; 
      echo '<td>'.$item['id'].'</td>'; 
      echo '<td>'.$item['quantity'].'</td>'; 
      echo "<td></td>"; 
      echo "<td>" . number_format($item['counterExtended'],2) . "</td>"; 
      echo "<td>" . number_format($item['onlineExtended'],2) . "</td>"; 
      echo "<td>" . number_format($item['voucherExtended'],2) . "</td>"; 
      echo '<td>'.$item['description'].'</td>'; 
      echo '<td>'.$item['category'].'</td>'; 
      echo "</tr>\n"; 
     } 

     echo "<tr>"; 
     echo "<td colspan=4></td>"; 
     echo "<td><strong>" . number_format($summary['counterExtended'], 2) . "</strong></td>"; 
     echo "<td><strong>" . number_format($summary['onlineExtended'], 2) . "</strong></td>"; 
     echo "<td><strong>" . number_format($summary['voucherExtended'], 2) . "</strong></td>"; 
     echo "<td><strong>$category</strong>"; 
     echo "<td></td>"; 
     echo "</tr>"; 

     $counterGrand+=$summary['counterExtended']; 
     $onlineGrand+=$summary['onlineExtended']; 
     $voucherGrand+=$summary['voucherExtended']; 

    }
