小编Gil*_*les的帖子

我正在使用SplFileInfo和SplFileObject处理PHP中的文件.但当我试图"重新打开"一个文件时,它会让我大叫:

 SplFileObject::__construct(filemame): failed to open stream: Permission denied

我想我应该在重新打开之前关闭我的文件,但我无法确定如何. SplFile*没有close功能？!

我尝试使用命令在Ubuntu上使用composer创建一个Symfony2项目:

php composer.phar create-project symfony/framework-standard-edition projectpath

我得到了这个错误

Installing symfony/framework-standard-edition (dev-master 506ffaab8d8474db2512fca879ca4b9877616a1e)
  - Installing symfony/framework-standard-edition (dev-master master)

  Problem 1
    - Installation request for symfony/symfony == 2.1.9999999.9999999-dev -> satisfiable by symfony/symfony 2.1.x-dev.
    - Can only install one …

我正在使用Symfony2设计REST API.

对于POST和PUT请求,我使用的是FormType.就像是 :

class EmailType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('subject', 'textarea')
        [...]
        ;
    }

    public function getName()
    {
        return 'email';
    }
}

但是当我发布POST时,我必须传递具有名称空间的字段:

{
    "email": {
        "subject": "subject"
    }
}

但我不想要这个顶级命名空间!

有任何想法吗 ？
