Question

我想从xml中提取每个“ Marca”的详细信息。我的阵列应该为每个“ Marca”使用所有的“ Diametru”，所有的“ Latime”，所有的“ PCD”等。我正试图那样做，但是还是有问题。...我会很感激任何建议：

<?php
$jante = "http://vilavaleaprahovei.ro/kimea/feeds/alcarRO_wheels_feed.xml";

$xml=simplexml_load_file($jante);
$arrayName =array();

foreach($xml->Produs as $child)
{
    $arrayName['marca'] = (string)$child->Marca;

    if ($arrayName['marca'] == (string)$child->Marca){
            $arrayName['marca']['diametru'][] = (int)$child->Diametru;
            $arrayName['marca']['latime'][] = (int)$child->Latime;
            $arrayName['marca']['pcd'][] = (int)$child->PCD;
            $arrayName['marca']['pcd1'][] = (int)$child->PCD1;
            $arrayName['marca']['et'][] = (int)$child->ET;
            $arrayName['marca']['cb'][] = (int)$child->CB;
    }   
}

$arrayName['marca'] = array_unique($arrayName['marca']);
$arrayName['marca']['diametru'] = array_unique($arrayName['diametru']);
$arrayName['marca']['latime'] = array_unique($arrayName['latime']); 
$arrayName['marca']['pcd'] = array_unique($arrayName['pcd']);
$arrayName['marca']['pcd1'] = array_unique($arrayName['pcd1']);
$arrayName['marca']['et'] = array_unique($arrayName['et']);
$arrayName['marca']['cb'] = array_unique($arrayName['cb']);


print_r($arrayName);

所需输出结构的示例：

我认为您想要这样的东西：

<?php
$jante = "http://vilavaleaprahovei.ro/kimea/feeds/alcarRO_wheels_feed.xml";
$xml=simplexml_load_file($jante);
$items = [];  // prepare main array

foreach($xml->Produs as $child)
{
   // collect details of this current item:
   $item = [];
   $item['diametru'] = (int)$child->Diametru;
   $item['latime'] = (int)$child->Latime;
   $item['pcd'] = (int)$child->PCD;
   $item['pcd1'] = (int)$child->PCD1;
   $item['et'] = (int)$child->ET;
   $item['cb'] = (int)$child->CB;

   // add this item to the main array, structured by 'marca'
   $marca = (string)$child->Marca;
   $items[$marca][] = $item;   
}

var_dump($items);

编辑：
这是获得所需结构的新版本：

foreach($xml->Produs as $child)
{
   $marca = (string)$child->Marca;
   if(!isset($items[$marca])) {
       $items[$marca] = [];
   }
   $items[$marca]['diametru'][] = (int)$child->Diametru;
   $items[$marca]['latime'][] = (int)$child->Latime;
   $items[$marca]['pcd'][] = (int)$child->PCD;
   $items[$marca]['pcd1'][] = (int)$child->PCD1;
   $items[$marca]['et'][] = (int)$child->ET;
   $items[$marca]['cb'][] = (int)$child->CB;
}

// EDIT 2:
// to make the entries unique you could loop through marcas
foreach($items as $marca => $item) {
   $items[$marca]['diametru'] = array_unique($items[$marca]['diametru']);
   $items[$marca]['latime'] = array_unique($items[$marca]['latime']);
   // repeat for other fields...

}
