Question

这是我要在Array中显示的HTML table。

$itemss =array(
array( "name"=>"Blue Pen", "Description"=>"Atlas", "UnitPrice"=>13.50, " AvailableStock "=>200),
array( "name"=>"80 P-Book", "Description"=>"Atlas", "UnitPrice"=>65," AvailableStock "=>100),
array( "name"=>"A4 Paper 500", "Description"=>"Atlas",  "UnitPrice"=>500," AvailableStock "=>20),
array( "name"=>"Red Pen", "Description"=>"Atlas", "UnitPrice"=>13.50," AvailableStock "=>256),
array( "name"=>"Back Pen", "Description"=>"Atlas",  "UnitPrice"=>13.50," AvailableStock "=>156) );

表格中的输出应该是这样的。

Item Name    |Description|Unit Price|Available Stock|Stock Value

Blue Pen         Atlas      13.50       200           xxxx


Total Stock Value                                   |xxxxxx

这就是我现在所做的事情：

<?php
$itemss =array(
array( "name"=>"Blue Pen", "Description"=>"Atlas","UnitPrice"=>13.50,"AvailableStock"=>200),
array( "name"=>"80 P-Book", "Description"=>"Atlas", "UnitPrice"=>65," AvailableStock"=>100),
array( "name"=>"A4 Paper 500","Description"=>"Atlas","UnitPrice"=>500,"AvailableStock"=>20),
array( "name"=>"Red Pen", "Description"=>"Atlas", "UnitPrice"=>13.50,"AvailableStock"=>256),
array( "name"=>"Back Pen", "Description"=>"Atlas", "UnitPrice"=>13.50,"AvailableStock"=>156) );


?>
<table border="1">
<tr>
<th>Item Name</th>
<th>Description</th>
<th>Unit Price</th>
<th>Available Stock</th>
<th>Stock Value</th>


</tr>
<?php
foreach($itemss as $Rockband)
{
echo '<tr>';
foreach(array_values($Rockband) as $key => $item)
{
echo "<td>$item</td>";

}
echo '</tr>';
}
?>
</table>

Answer 1

<table border="1">
<tr>
<th>Item Name</th>
<th>Description</th>
<th>Unit Price</th>
<th>Available Stock</th>
<th>Stock Value</th>


</tr>
<?php
$TotalStockValue = 0;

foreach($itemss as $Rockband)
{
    echo '<tr>';
    foreach( $Rockband as $key => $value )
    {
        echo "<td>$value</td>";
    }
    $StockValue = ( $Rockband["UnitPrice"] * $Rockband["AvailableStock"] );
    echo '<td>' . $StockValue . '</td>';
    echo '</tr>';

    $TotalStockValue += $StockValue;
}
echo '<tr><td colspan="4">Total Stock Value</td><td>' . $TotalStockValue . '</td></tr>';
?>
</table>

Answer 2

您可以使用list函数

在这样的数组上使用foreach

$total_stock_value = 0;

foreach($itemss as $one_item) {
    // map the array values to the variables
    list($name, $desc, $price, $stock) = $one_item; 
    $stock_val = $price * $stock;
    $total_stock_value += $stock_val;

    echo '<tr><td>' . $name . '</td><td>' . $desc . '</td><td>...</td></tr>';
}

这应该打印出你所描述的表格的正文。你有一个数组数组。因此，上面的代码遍历$itemss的每个项目，逐个读取单个数组$one_item，并为每个数组列出（或映射，如果您愿意）该子数据的值$one_item到给定的变量（$name, $desc, ...)。然后我只是以你在问题中描述的格式输出变量。

修改我看到了有关Stock Value和Total Stock Value的更新内容，因此我对我的回答进行了更精确的修改。

Answer 3

你走在正确的轨道上。但是，您不需要使用array_values。

<?php
$totalValue= 0;
foreach($itemss as $Rockband)
{
    $stockValue = $Rockband["UnitPrice"] * $Rockband["AvailableStock"];
    $totalValue += $stockValue;
    echo '<tr>';
    foreach( $Rockband as $key => $value )
    {
        echo "<td>$value</td>";
    }
    echo "<td>$stockValue</td>";
    echo '</tr>';
}

echo $totalValue;
?>
