How to use PHP to implement product SKU functions of multiple specifications

With the continuous development of the e-commerce industry, product SKU (Stock Keeping Unit, inventory unit) management has changed. becomes more and more important. Product SKU refers to a unique identifier set for each product in inventory management, including the identification information and description of the product.

On e-commerce platforms, products often have multiple specifications and attributes, such as size, color, material, etc. In order to facilitate management and sales, operators need to generate corresponding SKUs based on different specification combinations and manage and track inventory.

In this article, we will introduce how to use PHP language to implement product SKU functions of multiple specifications, and give corresponding code examples.

1. Data structure design

First, we need to design a data structure for storing SKU information. In this data structure, each specification corresponds to an attribute group, and the attribute group contains multiple attribute values. The specific data structure is as follows:

<?php
class SKU {
  public $id;
  public $name;
  public $properties;
}

class PropertyGroup {
  public $name;
  public $values;
}

class PropertyValue {
  public $name;
  public $price;
  public $stock;
}
?>

In this data structure, the SKU object contains one or more PropertyGroup objects, and each PropertyGroup object contains multiple PropertyValue objects. PropertyName represents the name of the property, Price represents the price corresponding to the property, and Stock represents the inventory corresponding to the property.

2. Generate SKU

Next, we need to generate SKU based on the product specification information. Before generating SKU, we need to define the product specifications and attribute values. Here is an example that shows the specifications and attribute values ​​of a T-shirt:

<?php
$sku = new SKU();
$sku->id = "001";
$sku->name = "T恤";
$sku->properties = array();

$propertyGroup1 = new PropertyGroup();
$propertyGroup1->name = "尺寸";
$propertyGroup1->values = array();

$propertyValue1 = new PropertyValue();
$propertyValue1->name = "S";
$propertyValue1->price = 19.99;
$propertyValue1->stock = 100;
$propertyGroup1->values[] = $propertyValue1;

$propertyValue2 = new PropertyValue();
$propertyValue2->name = "M";
$propertyValue2->price = 19.99;
$propertyValue2->stock = 150;
$propertyGroup1->values[] = $propertyValue2;

$propertyValue3 = new PropertyValue();
$propertyValue3->name = "L";
$propertyValue3->price = 19.99;
$propertyValue3->stock = 200;
$propertyGroup1->values[] = $propertyValue3;

$sku->properties[] = $propertyGroup1;

$propertyGroup2 = new PropertyGroup();
$propertyGroup2->name = "颜色";
$propertyGroup2->values = array();

$propertyValue4 = new PropertyValue();
$propertyValue4->name = "红色";
$propertyValue4->price = 19.99;
$propertyValue4->stock = 100;
$propertyGroup2->values[] = $propertyValue4;

$propertyValue5 = new PropertyValue();
$propertyValue5->name = "蓝色";
$propertyValue5->price = 19.99;
$propertyValue5->stock = 150;
$propertyGroup2->values[] = $propertyValue5;

$sku->properties[] = $propertyGroup2;
?>

In the above code example, we have defined a T-shirt SKU, and its specifications include size and color. Each attribute value has a corresponding price and inventory.

3. Generate all SKU combinations

After we have the product specifications and attribute values, we need to generate SKUs for all specification combinations. Below is a code example that uses recursion to generate all SKU combinations:

<?php
function generateSKUs($sku, $index, $combination, &$result) {
  if ($index >= count($sku->properties)) {
    $result[] = $combination;
    return;
  }

  $propertyGroup = $sku->properties[$index];
  for ($i = 0; $i < count($propertyGroup->values); $i++) {
    $propertyValue = $propertyGroup->values[$i];
    $newCombination = $combination;
    $newCombination[] = $propertyValue;
    generateSKUs($sku, $index + 1, $newCombination, $result);
  }
}

$result = array();
generateSKUs($sku, 0, array(), $result);
?>

In the above code example, the generateSKUs function is used to generate all SKU combinations. It uses recursion to traverse all specification combinations and saves the results in the $result array.

4. Use SKU

After generating all SKU combinations, we can perform inventory management and sales based on these SKU combinations. The following is a simple example:

<?php
foreach ($result as $combination) {
  $skuId = $sku->id;
  $skuName = $sku->name;
  $prices = array();
  $stocks = array();

  foreach ($combination as $propertyValue) {
    $skuName .= " " . $propertyValue->name;
    $prices[] = $propertyValue->price;
    $stocks[] = $propertyValue->stock;
  }

  $price = min($prices);
  $stock = min($stocks);

  echo "SKU ID: " . $skuId . "<br>";
  echo "SKU Name: " . $skuName . "<br>";
  echo "Price: " . $price . "<br>";
  echo "Stock: " . $stock . "<br>";
  echo "<br>";
}
?>

In the above code example, we iterate through all SKU combinations, calculate the price and inventory based on the attribute values ​​of each combination, and output the corresponding information.

Using PHP to implement the product SKU function of multiple specifications can easily manage and sell products of multiple specifications. By generating different SKU combinations, we can select products according to different specifications, check prices, inventory and other information. With this function, e-commerce operators can sell goods more flexibly and improve user experience.
