Files and Directories

The framework provides a simple component to work with the filesystem. The component is available in all of the application bundles.

Directory Registry

Most of the Spiral components rely on the directory registry instead of hard-coded paths. The registry is represented using Spiral\Boot\DirectoriesInterface.

You can configure application specific directories in the app entry point (app.php):

php
$app = \App\App::create([
    'root'      => __DIR__,
    'customDir' => __DIR__ . '/custom'
])->run();

Or using the Bootloader:

php
namespace App\Bootloader;

use Spiral\Boot\Bootloader\Bootloader;
use Spiral\Boot\DirectoriesInterface;

class AppBootloader extends Bootloader
{
    public function boot(DirectoriesInterface $directories)
    {
        $directories->set(
            'customDir',
            $directories->get('root') . '/custom'
        );
    }
}

To access the directory paths:

php
namespace App\Controller;

use Spiral\Boot\DirectoriesInterface;

class HomeController
{
    public function index(DirectoriesInterface $dirs)
    {
        dump($dirs->get('root'));
        dump($dirs->get('customDir'));

        dump($dirs->getAll());
    }
}

Note
You can also use the short function directory inside your config files. Note that this function does not work outside of the framework as it relies on the global container scope.

Files

Use the Spiral\Files\FilesInterface component to work with the filesystem:

php
namespace App\Controller;

use Spiral\Files\FilesInterface;

class HomeController
{
    public function index(FilesInterface $files)
    {
        // get all files from root directory recursively
        dump($files->getFiles(directory('root')));
    }
}

You can also access this instance using prototyped property files:

php
namespace App\Controller;

use Spiral\Prototype\Traits\PrototypeTrait;

class HomeController
{
    use PrototypeTrait;

    public function index()
    {
        dump($this->files->exists(__FILE__)); // true
    }
}

Create Directory

To ensure that a given directory exists, use method ensureDirectory, the second argument accepts the access permission:

php
namespace App\Controller;

use Spiral\Boot\DirectoriesInterface;
use Spiral\Files\FilesInterface;
use Spiral\Prototype\Traits\PrototypeTrait;

class HomeController
{
    use PrototypeTrait;

    public function index(DirectoriesInterface $dirs)
    {
        $this->files->ensureDirectory(
            $dirs->get('customDir'),
            FilesInterface::READONLY // or FilesInterface::RUNTIME for editable dirs and files
        );
    }
}

To check if a directory exists:

php
dump($files->isDirectory(__DIR__));

Delete Directory

To delete a directory and its content:

php
$files->deleteDirectory('custom');

To delete directory content only:

php
$files->deleteDirectory('custom', true);

File Stats

To check if a file exists:

php
dump($files->exists(__FILE__)); // bool

To get file creation/update time:

php
dump($files->time(__FILE__)); // unix timestamp

To get file MD5:

php
dump($files->md5('filename'));

To get a filename extension:

php
dump($files->extension(__FILE__)); // without leading "."

To check if the path is a file:

php
dump($files->isFile(__DIR__));

To get the file size:

php
dump($files->size(__DIR__));

Permissions

To get file/directory permissions:

php
dump($files->getPermissions(__FILE__)); // int

To set file permissions:

php
$files->setPermissions(__FILE__, 0777)

Use constants to control the file mode:

Constant Value
FilesInterface::READONLY 644
FilesInterface::RUNTIME 666

Move and Copy

To copy a file from one path to another:

php
$files->copy('old-path', 'new-path');

To move a file:

php
$files->move('old-path', 'new-path');

Temporary Files

To issue a temporary filename:

php
dump($files->tempFilename());

To issue a temporary filename with a specific extension:

php
dump($files->tempFilename('php'));

To issue a temporary filename in a specific location:

php
dump($files->tempFilename('php', __DIR__));

Read and Write operations

The component provides multiple methods to operate with file content in an atomic way (without acquiring the file resource):

Write/Create file

To write content to a file (exclusive lock):

php
$files->write('filename', 'data');

To write/create a file and ensure a proper access mode:

php
$files->write('filename', 'data', 0777);

To check and automatically create a file directory:

php
$files->write('filename', 'data', 0777, true);

Note
Make sure to handle Spiral\Files\Exception\WriteErrorException if the file can is not writable.

Append Content

To append file content:

php
$files->append('filename', 'data');

To append and ensure a file mode:

php
$files->append('filename', 'data', 0777);

To append/create a file and ensure that a target directory exists:

php
$files->append('filename', 'data', 0777, true);

Touch

To touch the file and create it, if missing:

php
$files->touch('filename');

To touch the file and ensure a file mode:

php
$files->touch('filename', 0777);

Read the file

To read file content:

php
dump($files->read('filename'));

Note
Make sure to handle Spiral\Files\Exception\FileNotFoundException when files are not found.
