<?php
$ProductsTest = array("1001" => array("Name" => "LCD","Desc" => "Sony","Qty" =>10,"Price" => 2000),
"1002" => array("Name" => "Mouse","Desc" => "Dell","Qty" =>3,"Price" => 300),
"1003" => array("Name" =>"Mouse","Desc" =>"a4Tech","Qty" =>3,"Price" =>300),
"1004" => array("Name" =>"USB","Desc" =>"Kingstton","Qty" =>15,"Price" =>700),
"1005" => array("Name" =>"HeadPhone","Desc" =>"a4Tech","Qty" =>7,"Price" =>3000));
$no_of_ele = count($ProductsTest);
echo '<br><br>';
echo ' <table border="2", bgcolor="white",width="100%"> 
<tr>
 <th>Name</th> 
    <th>Brand</th>
     <th>QTY</th> 
    <th>price</th>
    <th>totalamount</th>
  </tr>';
foreach( $ProductsTest as $values)
{
    echo '<tr>';
    foreach( $values as $key )
    {
        echo '<td>'.$key.'</td>';
  }
    echo '</tr>';

对于使用函数式编程的这个问题，这是一个很好的解决方案，您可以映射数组以使用totalamount返回其他数组

    <!doctype html>
        <html>
        <head>
        <meta charset="utf-8">
    <title>Untitled Document</title>
    </head>

    <body>
    <?php
    $lists = array("1001" => array("Name" => "LCD","Desc" => "Sony","Qty" =>10,"Price" => 2000),
    "1002" => array("Name" => "Mouse","Desc" => "Dell","Qty" =>3,"Price" => 300),
    "1003" => array("Name" =>"Mouse","Desc" =>"a4Tech","Qty" =>3,"Price" =>300),
    "1004" => array("Name" =>"USB","Desc" =>"Kingstton","Qty" =>15,"Price" =>700),
    "1005" => array("Name" =>"HeadPhone","Desc" =>"a4Tech","Qty" =>7,"Price" =>3000));

    $ProductsTest  = array_map(function($item){
        $item['totalamount'] = $item['Qty'] * $item['Price'];
        return $item;
    },$lists);
$no_of_ele = count($ProductsTest);
    echo '<br><br>';
    echo ' <table border="2", bgcolor="white",width="100%"> 
    <tr>
     <th>Name</th> 
        <th>Brand</th>
         <th>QTY</th> 
        <th>price</th>
        <th>totalamount</th>
      </tr>';
    foreach( $ProductsTest as $values)
    {
        echo '<tr>';
        foreach( $values as $key )
        {
            echo '<td>'.$key.'</td>';
        }
        echo '</tr>';
    }

    echo '</table>';
    ?>
