使用以下代码

获取我的功能

$response = simplexml_load_file($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>';

                        }

                    }
            }

        }

但我无法获得产品功能。

Answer 1

您的$ sql_features变量可能超出范围，请尝试这种方式

 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>';
   }
