乗算2のキー値

Question

私のコードのように行く：

<?php   
    $items = array(
     array("SKU" => "a49w8dsa", "Title" => "Socks", "Description" => "Sports socks", "Price" => "1.50", "Quantity" => "4"), 
     array("SKU" => "ta8dla", "Title" => "T-shirt", "Description" => "ABC Brand undershirt", "Price" => "14.25", "Quantity" => "2"), 
     array("SKU" => "yusa982", "Title" => "Flip Flips", "Description" => "XYZ Brand Beach Flops", "Price" => "2.88", "Quantity" => "5"), 
     array("SKU" => "gnbaiue", "Title" => "Ball Cap", "Description" => "No Name", "Price" => "3.58", "Quantity" => "1"), 
     array("SKU" => "ythwq836", "Title" => "Frizbee", "Description" => "Whammo Frisbee Disc", "Price" => "2.47", "Quantity" => "2") 
    ); 
?> 

<?php if (count($items) > 0): ?> 
     <table> 
      <thead> 
      <tr> 
       <th><?php echo implode('</th><th>', array_keys(current($items))); ?></th> 
      </tr> 
      </thead> 
      <tbody> 
    <?php foreach ($items as $row): array_map('htmlentities', $row); ?> 
      <tr> 
       <td><?php echo implode('</td><td>', $row); ?></td> 
      </tr> 
    <?php endforeach; ?> 
      </tbody> 
     </table> 
     <?php endif; ?> 






<?php 

    $final = array_shift($items); 
foreach (array_column as $key => &$value){ 
$value += array_sum(array_row($Price . $Quantity)); 
    } 

unset($value); 

    var_dump($final); 
    ?> 

私は、その後、各アイテムの価格をつかむその配列に数量を乗算し、変数に合計を追加します印刷します。私はこれでちょっと新しいので、私の解読したコードを許してください！

Answer 1

配列に各アイテムの取得価格は、最終的に使用し、それを合計array_sum() -

$eachPrice = array(); 
foreach ($items as $key => $val) { 
    $eachPrice[] = $val['Price'] * $val['Quantity']; 
} 

$totalPrice = array_sum($eachPrice); 

var_dump($totalPrice); // should be total price of all items
