PHP e-commerce system development: Frequently Asked Questions

When developing a PHP e-commerce system, you often encounter some common problems. This article will explain some common questions and provide PHP-based code examples to assist development.

    'currency' => 'usd',
    'payment_method_types' => ['card'],
]);

Question 2: How to manage product catalog?

// 使用 Eloquent 模型
use App\Product;

$product->price = 2000;
$product->save();

Question 3: How to design the shopping cart mechanism?

Question 4: How to provide product search function?

// 使用 ElasticSearch 查询
use Elasticsearch\ClientBuilder;

$client = ClientBuilder::create()->build();

$params = [
    'index' => 'products',
    'type' => 'product',
    'body' => [
        'query' => [
            'match' => [

// 使用缓存机制
use Cache;

// 缓存产品数据
Cache::put('products', Product::all(), 60);

Question 6: How to solve the security problem?

// 使用 OWASP ESAPI
use OWASP\ESAPI\ESAPI;

$esapi = new ESAPI();

// 清理用户输入

Question 7: How to conduct system testing?

// 使用 PHPUnit
use PHPUnit\Framework\TestCase;

class ProductTest extends TestCase
{
    public function testCreateProduct()
    {
        // 在数据库中创建产品
        $product = new Product;
        $product->name = 'T-shirt';
        $product->price = 2000;
        $product->save();

        // 检查产品是否成功创建
        $this->assertDatabaseHas('products', [
            'name' => 'T-shirt',
            'price' => 2000
