PHP Luminova: Integrating Third-Party Cloud Storage Services

The Storage class provides an interface for interacting with various storage adapters such as local file storage, FTP servers, in-memory storage, and cloud storage services like AWS S3, Azure Blob, and Google Cloud Storage. This class serves as an extension of the powerful PHP library League Filesystem, which offers convenient methods for common file and directory operations.

To get started with the Storage class, ensure that you have installed the filesystem package by running the Composer command.

composer require league/flysystem:^3.0

Additionally, make sure to install the required dependencies for the chosen storage driver. You can refer to the configuration for the required drivers depending on the storage you want in the League Storage Filesystem Configuration documentation.

Examples

Base usage, write to local storage.

use Luminova\Storages\Storage;

Storage::context(Storage::LOCAL)
    ->write('example.txt', 'Hello, World!');

To save file and generate a symbolic public URL on the go, use toLink method.

use Luminova\Storages\Storage;

echo Storage::context(Storage::LOCAL)
    ->write('example.txt', 'Hello, World!')
    ->toLink();

Note: This method is only for local storage context, for other cloud storage use url method.

To change directory, create the folder and write file to it.

use Luminova\Storages\Storage;

echo Storage::context(Storage::LOCAL)
    ->disk('foo')
    ->write('example.txt', 'Hello, World!');

Use the disk method to change directory and create a new directory.

If you want to change directory without creating the folder use chdir method.

use Luminova\Storages\Storage;

$dir = Storage::context(Storage::LOCAL)
    ->chdir('foo/bar/baz')
    ->mkdir(null); /* Pass null since we already prepare the dir */

Note: The chdir method doesn't change your directory remotely, it only prepare the directory for next execution.

Upload file to server, you can optionally set file configuration using setConfig method.

$file = $request->getFile('file');
$file->setConfig([
    'max_size' =>  1024,
    'min_size' =>  500,
]);

$uploaded = Storage::context(Storage::LOCAL)->upload($file);

if($uploaded){
    echo 'Upload was successful';
}

If the provided $directory is an empty string, . or ./, it resets back to the main storage root.

public chdir(string $directory = './'): self

Return Value:

self - Returns the instance of storage class.

Use an empty string, . or ./ to return to root.

url

Return Value:

string|null - Return remote url to file otherwise null.

symbolic

write

Writes contents to a file in current working directory.

public write(string $filename, string|resource $contents, bool $steam = false): self

Return Value:

self - Class instance.

Throws:

• \Luminova\Exceptions\StorageException - If an error occurs during the write operation.

Upload file in working directory.

public upload(\Luminova\Http\File $file): bool

Parameters:

Return Value:

bool - Return true if upload was successful false otherwise.

toLink

Create a symbolic link after writing file to disk.

public toLink(): string|false

Return Value:

string|false - The symbolic link location or false on failure.

This method is only available on local filesystem.
