Load file content inside controller in symfony 2
提问by Ladislav M
I have a css file called 'style.css' and I want to load its content inside a controller. I didn't find any relevant solution when reading the official documentation (Cookbook included).

I think you would first need to get the path to the CSS directory, using something like:
我认为您首先需要使用以下内容获取 CSS 目录的路径：
$path = $this->get('kernel')->getRootDir() . '/../css' . '/path/to/file.css';
Then, load the CSS file into a string:
然后，将 CSS 文件加载到字符串中：
$css = file_get_contents($path);
Hope that helps!
希望有帮助！

I found a simple solution if you have the path to the file then
如果您有文件的路径，我找到了一个简单的解决方案
$file = new SplFileInfo('/path/to/file.css', '', '');
and the method getContentsdoes the magic
这个方法很getContents神奇
$file->getContents();
But you will have to include the class
但你必须包括课程
use Symfony\Component\Finder\SplFileInfo;
is also part of the finder library, but you don't need to search for the file you want to read.
也是 finder 库的一部分，但您不需要搜索要阅读的文件。
