. 그것은 사용자가 입력 한 데이터에 따라 다릅니다. 이제 키 배열 [products]을 가진 각 내부 배열에서이 배열을 자세히 관찰하면 더 많은 배열이 있습니다. 그러나이 내부 배열들 각각에 [products] 키 아래에있는 키 [manufacturer_id]은 이와 관련된 값이 과 관련이 있습니다.

이 값을 새 변수에 할당하려고합니다. 위의 배열에서 데이터를 원하지 않습니다. 그래서이 큰 배열에서 단일 값을 얻는 것이 많은 루프를 적용하는 것이 좋지 않을 것이라고 생각합니다. 이 값을 최소한으로 줄이고 싶습니다. 코드 줄 수 어떻게해야합니까?

제발 도와 줄 수 있습니까?

Answer 1

루프를 결정한 경우. 당신이 반복하고 싶지 않다고 말한 건 알지만, 3 루프는 그리 많지 않습니다. 어쨌든 나는 너를 위해 그것을 했어. 너 마음을 바꾸기로 결정한거야.

//Loop through your array 
foreach($rebate_by_product_data AS $key => $product_data){ 
    //Check if the rebate_product instance has been set 
    if(!isset($product_data['rebate_product'])){ 
     //If it hasn't skip this loop continue onto the next 
     continue; 
    } 
    //Loop through the rebate_products 
    foreach($product_data['rebate_product'] AS $products){ 
     //rebate_products should all have manufacturer_id's ? 
     foreach($products AS $product){ 
      //Get your manufacturer ID. 
      $manufacturer_id = $product['manufacturer_id']; 
     } 
    } 
} 

정말로 루프하지 않으려면.

//Second way is to just call the indexes off one by one, statically, if you only need one instance of the manufacturer_id 
$manufacturer_id = $rebate_by_product_data[0]['rebate_product'][0]['products'][0]['manufacturer_id']; 

베어 마음에 나는 당신의 배열을 다시 만듭니다하지 않았다. 그래서 실수가있을 수 있습니다. 필요한 경우 루프 또는 정적 호출을 조정합니다.
