PHP的foreach循環只返回最後一個元素？

Question

我有一個應用程序必須從提供商獲取一些數據。 爲此，我在db中有一些數據，並通過服裝MVC模型中的模型加載它，並嘗試獲取數組中的所有數據（assoc），它的工作原理完全正確。

最後我想收集所有的列表並將列表從類傳遞給控制器​​。

我之前爲這個類中的其他參數做過，但現在當我想收集它時，它只返回最後一條記錄！

這裏是代碼：

public function getDetails() 
{ 

    $provider = []; 

    $provider['local']['images'] = $this->loadModel('images')->getProviderImages($this->provider_id); 
    $provider['local']['applications'] = $this->loadModel('images')->getProviderApplications($this->provider_id); 
    $provider['local']['plans'] = $this->loadModel('plans')->getProviderPlans($this->provider_id); 
    $provider['local']['dataCenters'] = $this->loadModel('regions')->getProviderRegions($this->provider_id); 
    $provider['local']['snapshots'] = $this->loadModel('snapshots')->getProviderSnapshots($this->provider_id); 

    try { 
     $provider['remote']['images'] = $this->getImages()->images; 
     $provider['remote']['plans'] = $this->getPlans()->plans; 
     $provider['remote']['dataCenters'] = $this->getDataCenters()->data_centers; 

     if (!$provider['remote']['images'] || !$provider['remote']['plans'] || !$provider['remote']['dataCenters']) { 
      throw new Exception ("Can't connect to provider. creating provider details array failed!"); 
     } 
    } catch (Exception $e) { 
     log_error($e); 

     return false; 
    } 
    /***********/ 


    $temp = []; 
    foreach ($provider['local']['images'] as $key => $image) { 
     foreach ($provider['remote']['images'] as $r_key => $r_image) {

//        r($r_image);

       $temp['snapshots'][$r_image['distribution']] = $r_image; 
       $temp['snapshots'][$r_image['distribution']]['service_provider'] = $snapshot['service_provider_id']; 
       $temp['snapshots'][$r_image['distribution']]['os_name'] = strtolower($r_image['distribution']); 

       break;

        $temp['applications'][$app['app_name']]['os'][$app['os_name']][$app['os_version'] . '-' . $app['os_architecture']]['dataCenters'] = $r_image['regions']; 

        if ($app['image_id'] != $r_image['id']) { 
         $this->loadModel('images')->updateImageID($this->provider_id, $app['slug'], $r_image['id']); 
        } 
        break; 
       } 
      } 
     } 
    }//die(); 


    foreach ($provider['local']['plans'] as $key => $plan) { 
     foreach ($provider['remote']['plans'] as $r_key => $r_plan) { 
      //echo "{$plan['slug']} == {$r_plan->slug} | "; 
      if ($plan['slug'] == $r_plan['slug'] && $r_plan['available']) { 
       $temp['plans'][$plan['slug']] = $plan; 
       $temp['plans'][$plan['slug']]['dataCenters'] = $r_plan['regions']; 

       break; 
      } 
     } 
    } 

    // sort by plan's price 
    uasort($temp['plans'], function ($a, $b) { 
     return $a['hourly_price'] > $b['hourly_price']; 
    }); 

    foreach ($provider['local']['dataCenters'] as $key => $dc) { 
     foreach ($provider['remote']['dataCenters'] as $r_key => $r_dc) { 
      //echo "{$dc['slug']} == {$r_dc->slug} | "; 
      if ($dc['slug'] == $r_dc['slug'] && $r_dc['available']) { 
       $temp['dataCenters'][$dc['country']][$dc['city']][$dc['slug']] = $dc; 
       $temp['dataCenters'][$dc['country']][$dc['city']][$dc['slug']]['plans'] = $r_dc['sizes']; 
       $temp['features'][$dc['slug']] = $r_dc['features']; 
       break; 
      } 
     } 
    } 

    return $temp; 
} 

我的問題是，這些行：

>   foreach ($provider['local']['snapshots'] as $key => $snapshot) { 
>   foreach ($provider['remote']['images'] as $r_key => $r_image) { 
>    if ($snapshot['snapshot_id'] == $r_image['id']) { 
> 
>     $temp['snapshots'][$r_image['distribution']] = $r_image; 
>     $temp['snapshots'][$r_image['distribution']]['service_provider'] = $snapshot['service_provider_id']; 
>     $temp['snapshots'][$r_image['distribution']]['os_name'] = strtolower($r_image['distribution']); 
> 
>     break; 
>    } 
>   } 
>  } 

Answer 1

終於讓我找到了awnser，我schuould使用一些變量作爲指標，像這樣：

$temp['snapshots'][$snapshot['id']] = $r_image; 

它工作，
