How to use array to display order form in php

In PHP, it is a very common practice to use arrays to display order orders. An order order is a document involving multiple varieties and quantities, and is widely used in daily life and business. Using arrays to display order orders can make data easy to operate, count, and analyze. In this article, we will explore how to use an array to display order orders.

1. How to create an order order array

In PHP, you can use an array to represent an order order. We can store various aspects of the order order, such as product name, quantity, unit price, etc., in an array. The following is a simple example:

$orders = array(
        array("商品名称"=>"苹果", "数量"=>10, "单价"=>5),
        array("商品名称"=>"香蕉", "数量"=>5, "单价"=>3),
        array("商品名称"=>"橙子", "数量"=>7, "单价"=>4),
        array("商品名称"=>"葡萄", "数量"=>12, "单价"=>6),
    );

This array contains four sub-arrays, each sub-array represents information about a product, including product name, quantity, and unit price. Next we will introduce this array in detail.

2. How to display the order form array

If you want to print the entire order form, you can use a loop to process each element in the array. The following is an example:

$total = 0;  // 初始化总价
foreach($orders as $order){
    // 计算每个订单的总价
    $subtotal = $order["数量"] * $order["单价"];
    $total += $subtotal;  // 累加每个订单的总价
    // 输出每个订单的信息
    echo $order["商品名称"] . " x " . $order["数量"] . " = " . $subtotal . "<br>";
}
echo "<br>总价：" . $total;

In this example, a foreach loop is used to process each element in the array and calculate the total price of each order. Finally, the information of each order is output, and the total price is output.

3. How to operate the order order array

Array is a particularly flexible data type. PHP provides many functions to operate on the array. The following are some examples of operations on order order arrays:

1. Count the number of items in the order order

$item_count = 0;  // 初始化商品数量
foreach($orders as $order){
    $item_count += $order["数量"];  // 统计商品数量
}
echo "商品数量：" . $item_count;

2. Find the quantity of a certain item in the order order

$search_item = "苹果";
foreach($orders as $order){
    if($order["商品名称"] == $search_item){
        echo $search_item . " 数量：" . $order["数量"];
    }
}

3. Sort order orders by product name

function cmp($a, $b){
    return strcmp($a["商品名称"], $b["商品名称"]);
}
usort($orders, "cmp");

foreach($orders as $order){
    echo $order["商品名称"] . " x " . $order["数量"] . "<br>";
}

In this example, the usort function is used to sort the array. The sorting rule is based on product name. Sort.

4. Summary

Using arrays to display order orders is a very convenient method. It can make data easy to process, count, and analyze. In this article, we introduced how to create an order array, how to display an order array, and how to operate on an order array. In actual development, the array can be further expanded and optimized according to specific needs.
