Question

我有这样的数组。

Array ( 
       [1] => Array ( 
                     [Stock Code] => 1Y 1111 
                     [Price] => 20 
                     [Quantity] => 10 
                     [Amount] => 200 
                    ) 

       [2] => Array ( 
                     [Stock Code] => 0300058 
                     [Price] => 30 
                     [Quantity] => 2 
                     [Amount] => 60 
                    ) 
      )

这里是我使用foreach循环从数组中检索值的代码。

<?php
  $cartOutput = "";
  $i=0;
  foreach($_SESSION['cart_array'] as $each_item){
    $i++;
        $cartOutput = "Stock Code: ".$each_item['Stock Code']."<br/>";
        $cartOutput = "Price: ".$each_item['Price']."<br/>";
        $cartOutput = "Quantity: ".$each_item['Quantity']."<br/>";
        $cartOutput = "Amount: ".$each_item['Amount']."<br/>";
  }
?>

这是我在HTML中显示结果的地方

<div style="height:500px;">
<?php echo $cartOutput; ?>
</div>

输出结果为：

金额：60

但我期望结果显示数组的所有值。

Answer 1

你在每次迭代中覆盖变量。而不是尝试将值附加到变量。试试这样

$cartOutput = "";
  $i=0;
  foreach($_SESSION['cart_array'] as $each_item){
    $i++;
        $cartOutput .= "Stock Code: ".$each_item['Stock Code']."<br/>";
        $cartOutput .= "Price: ".$each_item['Price']."<br/>";
        $cartOutput .= "Quantity: ".$each_item['Quantity']."<br/>";
        $cartOutput .= "Amount: ".$each_item['Amount']."<br/>";
  }

Answer 2

在你的foreach循环中你应该有

$cartOutput .=

而不仅仅是=

从多维数组php中检索值
