Question

아마존 제품 광고 API를 사용하고 ASIN 값을 사용하여 제품 세부 정보를 가져옵니다. XML 형식의 데이터를 가져오고 있지만 제품의 기능을 분석하는 데 문제가 있습니다.

내가 코드

$response = simplexml_load_file($request_url); 
if(isset($response->Items->Item)){ 
      echo 'yes'; 

      //$asin = $response->Items->Item->ASIN; 
      if(in_array($id, $json)){ //if id is in features array then continue 

       //if(isset($response->Items->Item->ItemAttributes)){ 
        echo '<br>Features<br>'; 
        foreach($response->Items->Item as $item){ 
         foreach($item->ItemAttributes->Feature as $fea){ 
          echo 'features '.trim($fea).'<br>'; 
          $value = str_replace("'", "%", trim($fea));//replaced " with ! because giving error in sql query 
          $value = str_replace('"', "!", trim($fea)); 
          if($value != '' || $value != NULL){ 
           $duplicate .= '("'.trim($id).'", "'.trim($asin).'", "'.trim($value).'") ,'; 
           $sql_features .= '("'.trim($id).'", "'.trim($asin).'", "'.$value.'") ,'; 
          } 

          echo $sql_features .'<br>'; 

         } 

        } 
      } 

     } 

이하로 사용하고 기능을 가져올하지만 제품의 기능을 얻을 수 아니에요.

Answer 1

귀하의 $ sql_features 변수, 범위에서,이 방법

if($value != '' || $value != NULL){ 
    $duplicate .= '("'.trim($id).'", "'.trim($asin).'", "'.trim($value).'") ,'; 
    $sql_features .= '("'.trim($id).'", "'.trim($asin).'", "'.$value.'") ,'; 

    // echo it inside if 
    echo $sql_features .'<br>'; 
    }
