php 商品筛选源码

<?php
// 假设有一个商品数组
$products = [
    ['id' => 1, 'name' => 'Product A', 'price' => 100, 'brand' => 'Brand X'],
    ['id' => 2, 'name' => 'Product B', 'price' => 200, 'brand' => 'Brand Y'],
    ['id' => 3, 'name' => 'Product C', 'price' => 150, 'brand' => 'Brand X'],
];

// 筛选条件
$filter = [
    'brand' => 'Brand X',
    'min_price' => 100,
    'max_price' => 200,
];

// 筛选函数
function filterProducts($products, $filter) {
    return array_filter($products, function($product) use ($filter) {
        if (isset($filter['brand']) && $product['brand'] !== $filter['brand']) {
            return false;
        }
        if (isset($filter['min_price']) && $product['price'] < $filter['min_price']) {
            return false;
        }
        if (isset($filter['max_price']) && $product['price'] > $filter['max_price']) {
            return false;
        }
        return true;
    });
}

// 执行筛选
$filteredProducts = filterProducts($products, $filter);

// 输出结果
print_r($filteredProducts);
