Flysystem Extension for Yii 2

This extension provides Flysystem integration for the Yii framework. Flysystem is a filesystem abstraction which allows you to easily swap out a local filesystem for a remote one.

This version requires Flysystem 3.x and PHP 8.1+

Usage

Writing files

To write a file

Yii::$app->fs->write('filename.ext', 'contents');

To write a file using stream contents

$stream = fopen('/path/to/somefile.ext', 'r+');
Yii::$app->fs->writeStream('filename.ext', $stream);

Reading files

To read a file

$contents = Yii::$app->fs->read('filename.ext');

To retrieve a read-stream

$stream = Yii::$app->fs->readStream('filename.ext');
$contents = stream_get_contents($stream);
fclose($stream);

Checking if a file exists

To check if a file exists

$exists = Yii::$app->fs->fileExists('filename.ext');

To check if a directory exists

$exists = Yii::$app->fs->directoryExists('path/to/directory');

Deleting files

To delete a file

Yii::$app->fs->delete('filename.ext');

Moving files

To move a file

Yii::$app->fs->move('filename.ext', 'newname.ext');

Copying files

To copy a file

Yii::$app->fs->copy('filename.ext', 'copy.ext');

Getting files mimetype

To get a file mimetype

$mimetype = Yii::$app->fs->mimeType('filename.ext');

Getting files last modified timestamp

To get a file last modified timestamp

$timestamp = Yii::$app->fs->lastModified('filename.ext');

Getting files size

To get a file size

$size = Yii::$app->fs->fileSize('filename.ext');

Creating directories

To create a directory

Yii::$app->fs->createDirectory('path/to/directory');

Directories are also made implicitly when writing to a deeper path

Yii::$app->fs->write('path/to/filename.ext', 'contents');

Deleting directories

To delete a directory

Yii::$app->fs->deleteDirectory('path/to/directory');

Managing visibility

Visibility is the abstraction of file permissions across multiple platforms. Visibility can be either public or private.

use League\Flysystem\Visibility;

Yii::$app->fs->write('filename.ext', 'contents', [
    'visibility' => Visibility::PRIVATE
]);

You can also change and check visibility of existing files

use League\Flysystem\Visibility;

if (Yii::$app->fs->visibility('filename.ext') === Visibility::PRIVATE) {
    Yii::$app->fs->setVisibility('filename.ext', Visibility::PUBLIC);
}

Listing contents

To list contents

$contents = Yii::$app->fs->listContents('', false);

foreach ($contents as $item) {
    echo $item->path();
    echo $item->isFile() ? 'file' : 'directory';
}

By default Flysystem lists the top directory non-recursively. You can supply a directory name and recursive boolean to get more precise results

$contents = Yii::$app->fs->listContents('path/to/directory', true);

Upgrading from v1

If you are upgrading from the Flysystem v1 version of this extension, please note the following breaking changes:

Removed Features

• Caching: The cached adapter is no longer available in Flysystem v3
• Replication: The replicate adapter is no longer available in Flysystem v3
• Rackspace: The Rackspace adapter has been removed as the service is discontinued
• NullFilesystem: Replaced with InMemoryFilesystem

API Changes

v1 Method	v3 Method
has($path)	fileExists($path) / directoryExists($path)
createDir($path)	createDirectory($path)
deleteDir($path)	deleteDirectory($path)
rename($path, $newpath)	move($source, $destination)
getTimestamp($path)	lastModified($path)
getMimetype($path)	mimeType($path)
getSize($path)	fileSize($path)
getVisibility($path)	visibility($path)
update() / put()	write()
updateStream() / putStream()	writeStream()

Visibility Constants

// Old (v1)
use League\Flysystem\AdapterInterface;
AdapterInterface::VISIBILITY_PRIVATE;
AdapterInterface::VISIBILITY_PUBLIC;

// New (v3)
use League\Flysystem\Visibility;
Visibility::PRIVATE;
Visibility::PUBLIC;
