您可以从控制器执行此操作:

use Symfony\Component\Filesystem\Filesystem;
use Symfony\Component\Filesystem\Exception\IOException;

//Define your file path based on the cache one
$filename = $this->container->getParameter('kernel.cache_dir') . '/yourapp/filename.txt';

//Create your own folder in the cache directory
$fs = new Filesystem();
try {
    $fs->mkdir(dirname($filename));
} catch (IOException $e) {
    echo "An error occured while creating your directory";
}

//Write your file
file_put_contents($filename, 'Text content');

//Read the content of your file    
echo file_get_contents($filename);
