Question

我有以下配置：

my_project:
    options:
        key1: value1
        key2: value2
        key3: value3
        key4: [sub1, sub2, sub3, sub4]

我的扩展程序不知道这些选项，我想获得一个关联数组：

array(
    "key1"=>"value1",
    "key"=>"value2",
    "key3"=>"value3",
    "key4"=>array("sub1","sub2","sub3","sub4") 
);

我的树看起来像：

$rootNode
    ->addDefaultsIfNotSet()
    ->children()
        ->arrayNode('options')
            ->useAttributeAsKey('key')
            ->treatNullLike(array())
            ->prototype('scalar')->end()
        ->end()
    ->end();

问题是，使用键/值“key4”，我有一个例外（这是正常的，因为原型是'数组'）。

所以我的问题是：我如何混合标量和数组选项？

感谢@lackovic的帮助！

这是我的解决方案：

public function load(array $configs, ContainerBuilder $container)
{
    $processor     = new Processor();
    $configuration = new Configuration($this->getAlias());

    $options = array();
    if(isset($configs[0]['options']))
    {
        $options = $configs[0]['options'];
        unset($configs[0]['options']);
    }
    $config = $processor->processConfiguration($configuration, $configs);


    // Now $options contains all the options and $config the configuration of my bundle
    ...
}

此解决方案还有助于包含子级别的配置：

my_project:
    options:
        key1: value1
        key2: value2
        key3: value3
        key4: [value1, value2, value3, value4]
        key5: 123
        key6: 
            subkey1 : [value5, value6, value7]

返回：

array
(
    "key1" => "value1"
    "key2" => "value2"
    "key3" => "value3"
    "key4" => array(
            0 => "value1"
            1 => "value2"
            2 => "value3"
            3 => "value4"
    )
    "key5" => 123
    "key6" => array(
        "value1" => array(
            0 => "value2"
            1 => "value3"
            2 => "value4"
        )
    )
)
