Implementation method and detailed explanation of product multi-specification SKU in PHP

How to implement multi-specification SKU of products in PHP and detailed explanation

In e-commerce platforms, multi-specification SKU (stock keeping unit) of products is very common . SKU can be understood as a combination of different attributes of a product, such as size, color, style, etc. Different SKUs correspond to different inventory amounts, and customers need to select a specific SKU when purchasing goods. In PHP, we can use arrays to manage and display multi-specification SKUs of products. This article will introduce the implementation of SKU in detail and provide corresponding code examples.

1. SKU data structure design

Before implementing SKU, we need to define the data structure of SKU. Usually, we can use an Associative Array to represent a SKU. The associative array can represent the attributes and inventory of each SKU, where the attributes are key-value pairs of attribute names and attribute values, and the inventory is an integer type value. The following is an example SKU data structure:

$sku = [
    '属性名1' => '属性值1',
    '属性名2' => '属性值2',
    // ...
    '库存量' => 100
];

2. SKU management and display

1. SKU management

In the e-commerce platform, Managing SKUs is very important. We can use a two-dimensional array to store all SKUs. Each element of the array is an associative array, representing a SKU. In this way, we can easily add, delete, modify and check SKUs. The following is an example SKU management array:

$skuArray = [
    [
        '属性名1' => '属性值1',
        '属性名2' => '属性值2',
        // ...
        '库存量' => 100
    ],
    // ...
];

2. Display of SKU

When a user purchases a product, we need to display the SKU of the product for the user to choose. We can use multi-dimensional arrays to display all attributes of the SKU and their corresponding attribute values. If the user selects different attribute values, the SKUs will be filtered based on the attribute values ​​selected by the user, thereby reducing the options the user selects. The following is an example SKU display array:

$skuDisplay = [
    '属性名1' => ['属性值1', '属性值2', ...],
    '属性名2' => ['属性值1', '属性值2', ...],
    // ...
];

3. SKU implementation code example

The following is a simple example code that uses PHP to implement multi-specification SKUs for products:

$skuArray = [
    [
        '颜色' => '红色',
        '尺寸' => 'S',
        '库存量' => 100
    ],
    [
        '颜色' => '红色',
        '尺寸' => 'M',
        '库存量' => 50
    ],
    [
        '颜色' => '蓝色',
        '尺寸' => 'S',
        '库存量' => 80
    ],
    [
        '颜色' => '蓝色',
        '尺寸' => 'M',
        '库存量' => 60
    ]
];

$skuDisplay = [
    '颜色' => ['红色', '蓝色'],
    '尺寸' => ['S', 'M']
];

echo "请选择商品属性：
";

foreach ($skuDisplay as $attrName => $attrValues) {
    echo "{$attrName}：";
    foreach ($attrValues as $attrValue) {
        echo "{$attrValue} ";
    }
    echo "
";
}

$userSelection = [];
foreach ($skuDisplay as $attrName => $attrValues) {
    $attrValue = readline("请选择 {$attrName}：");
    $userSelection[$attrName] = $attrValue;
}

$selectedSku = null;
foreach ($skuArray as $sku) {
    $matched = true;
    foreach ($userSelection as $attrName => $attrValue) {
        if ($sku[$attrName] != $attrValue) {
            $matched = false;
            break;
        }
    }
    if ($matched) {
        $selectedSku = $sku;
        break;
    }
}

if ($selectedSku) {
    echo "您选择的商品SKU是：
";
    foreach ($selectedSku as $attrName => $attrValue) {
        echo "{$attrName}：{$attrValue}
";
    }
    echo "库存量：{$selectedSku['库存量']}
";
} else {
    echo "没有匹配的商品SKU。
";
}

In the above example code, we use associative arrays to store SKUs and SKU display data, and use foreach loops and conditional judgments to select product SKUs. According to the attribute value selected by the user, the corresponding SKU can be found from the SKU array and displayed. In this way, users can easily select the SKU of the product and view the corresponding inventory.

Summary:

This article introduces the method and detailed explanation of using PHP to implement multi-specification SKU of products. Through the defined data structure and corresponding code processing logic, we can easily manage and display the multi-specification SKU of the product. I hope this article can be helpful to your e-commerce platform development.
