Flysystem is a PHP file storage library that provides a single unified interface for interacting with many types of filesystems, both local and remote. It ships with adapters for local disks, FTP/SFTP, AWS S3, Google Cloud Storage, Azure Blob, WebDAV, and more, protecting applications from storage vendor lock-in.

Use cases

• swap local file storage for S3 without rewriting code
• read and write files on FTP or SFTP servers through one API
• store uploads in Google Cloud Storage or Azure Blob Storage
• abstract file operations across multiple storage backends
• avoid vendor lock-in when choosing a cloud storage provider
• use in-memory or zip archive filesystems for testing

When to choose

• you need a consistent filesystem API across local and cloud storage in PHP
• you want to switch storage providers without changing application code
• you're building a PHP application or framework that supports pluggable storage

When to avoid

• you only ever target a single storage backend and want minimal dependencies
• you need streaming or performance-critical low-level filesystem access
• you're not working in PHP
