php商品筛选

<?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'],

// 获取筛选条件
$filter = $_GET['filter'] ?? [];

// 根据筛选条件进行筛选
if (!empty($filter['brand'])) {
    $products = array_filter($products, function ($product) use ($filter) {
        return $product['brand'] === $filter['brand'];

        return $product['price'] >= $filter['price_min'] && $product['price'] <= $filter['price_max'];
    });

// 输出筛选结果
