Question

我有一个必须从提供商处获取一些数据的应用。为此，我在db中有一些数据并通过服装MVC模型中的模型加载它并尝试获取数组（assoc）中的所有数据，它完全正确。

最后我想收集所有列表并将列表从类传递给控制器。

我之前在这个类中已经完成了其他参数，但现在当我想收集它时它只返回最后一条记录！

这是代码：

    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);

if ($image['slug'] == $r_image['slug']) {
                    $temp['images'][$image['os_name']]['name'] = $image['name'];
                    $version = $image['os_version'];
                    $version .= (!empty($image['os_architecture'])) ? '-' . $image['os_architecture'] : '';

                    }
                    break;
                }
            }
        }
    }//die();


    foreach ($provider['local']['plans'] as $key => $plan) {
        foreach ($provider['remote']['plans'] as $r_key => $r_plan) {

        }
    }

    return $temp;
}

我的问题在于以下几点：

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

Answer 1

最后我发现了awnser，我应该使用一些变量作为索引，如下所示：

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

它有效，

php foreach循环只返回最后一个元素？
