php商品条件筛选功能

<?php
// 假设有一个商品数组
$products = [
    ['id' => 1, 'name' => 'Product A', 'price' => 100, 'brand' => 'Brand X', 'category' => 'Category Y'],
    ['id' => 2, 'name' => 'Product B', 'price' => 200, 'brand' => 'Brand Y', 'category' => 'Category Z'],
    // 其他商品...
];

// 获取筛选条件
$minPrice = isset($_GET['minPrice']) ? intval($_GET['minPrice']) : 0;
$maxPrice = isset($_GET['maxPrice']) ? intval($_GET['maxPrice']) : 1000;
$brand = isset($_GET['brand']) ? $_GET['brand'] : '';
$category = isset($_GET['category']) ? $_GET['category'] : '';

// 筛选商品
$filteredProducts = [];
foreach ($products as $product) {
    if ($product['price'] >= $minPrice && $product['price'] <= $maxPrice &&
        ($brand === '' || $product['brand'] === $brand) &&
        ($category === '' || $product['category'] === $category)) {
        $filteredProducts[] = $product;
    }

// 输出筛选后的商品
foreach ($filteredProducts as $product) {
