Question

我有此选项列表，它是动态生成的：

 $prod_variants = json_decode($synresponsecolpr, true);

 foreach ($prod_variants["result"]["variants"] as $variant_color) {

 echo '<option variant_color_id="'.$variantid.'"
               value="'.$colorno.'" 
               class="productli">'.$variant_color['color'].'</option>';
     }

输出

<select>
<option value="" class="">Select Color</option>
<option variant_color_id="5522" class="productli">
 Heather White
</option>
<option variant_color_id="5523" class="productli">
Indigo
</option>
<option variant_color_id="5524" class="productli">
Premium Heather
</option>
</select>

每个选项都包含一个不同的varian_color_id，它指向这样的json数组中的特定product_id：

$products = json_decode($synresponsepr, true);
{
    "code": 200,
    "result": {
        "sync_product": {
            "id": 118421780,
            "external_id": "5d02d83a0c81e4",
            "name": "Hooded Sweatshirt - Black Logo - Men Hoodie",
            "variants": 29,
            "synced": 29
        },
        "sync_variants": [
            {
                "id": 1335748157,
                "external_id": "5d02d83a0c8345",
                "sync_product_id": 118421780,
                "name": "Hooded Sweatshirt - Black Logo - Men Hoodie - White / S",
                "synced": true,
                "variant_id": 5522,
                "retail_price": "29.00",
                "currency": "USD",
                "product": {
                    "variant_id": 5522,
                    "product_id": 146,
                    "image": "https://d1yg28hrivmbqm.cloudfront.net/products/146/5522_1526560589.jpg",
                    "name": "Gildan 18500 Unisex Heavy Blend Hooded Sweatshirt (White / S)"
                },

在这种情况下，带有Heather White的{{1}}选项指向json数组中的variant_color_id=5522 sync_product id。

如果唯一已知的是选项中的 variant_color_id ，如何使用它从数组中获取 sync_product id ？可以进行逆向工程吗？

我正在考虑检查数字是否是数组的一部分是一个好的开始：

118421780

Answer 1

无法使用in_array这样的深度搜索。
我认为这个琐碎的循环可以解决问题。

foreach ($products["result"]["sync_variants"] as $sv) {
  if ($sv['product']['variant_id'] == $variant_color_id) {  
    echo $variant_color_id . ' is sync_product_id ' . $products['result']['sync_product']['id'];
    break;
  }
}

如何从具有给定变量的数组中获取值？
