FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Overview
Daedalus is a powerful PHP library that provides advanced data structures and utilities for modern PHP applications. At its core, it offers an enhanced version of PHP's ArrayObject with additional features like type safety, event handling, immutability options, and a PSR-11 compliant dependency injection container.
The library is designed with a focus on type safety, immutability, and event-driven architecture, making it an ideal choice for building robust and maintainable applications.
Installation
Features
- Type safety for array elements
- Event handling for array modifications
- Immutable array support
- Array manipulation methods (map, filter, reduce)
- Deep cloning capability
- Array merging with type checking
- Event listener management
- PSR-11 compliant dependency injection container
- Singleton pattern support
- Automatic dependency resolution
Why Use Daedalus?
This library is particularly useful in scenarios where you need robust array handling with type safety and change tracking. Here are some real-world use cases:
1. E-commerce Product Catalogs
- Maintain type-safe collections of products
- Track changes to inventory in real-time using event listeners
- Filter and transform product lists efficiently
- Ensure data integrity with immutable product records
2. User Management Systems
- Manage collections of user objects with type enforcement
- Track user list modifications for audit logging
- Filter users based on roles or permissions
- Safely share user lists across system components
3. Financial Applications
- Maintain immutable transaction records
- Track changes to financial data with event listeners
- Perform calculations on collections of financial entries
- Ensure data consistency with type constraints
4. Content Management Systems
- Manage collections of different content types
- Track content modifications with event listeners
- Filter and transform content collections
- Maintain immutable content versions
5. API Response Handling
- Transform API responses into typed collections
- Cache immutable response data
- Filter and map response data efficiently
- Track data access patterns with events
6. Configuration Management
- Store immutable configuration settings
- Track configuration changes with events
- Maintain type-safe option collections
- Merge configuration from multiple sources
Data Structures
Dictionary
A type-safe key-value collection with:
- Strict type enforcement
- Iteration capabilities
- Serialization support
- Ideal for configurations and mappings
Example:
MultiMap
A map that allows multiple values per key:
- Store multiple values for a single key
- Maintain insertion order
- Type-safe value collections
- Ideal for tags, categories, and relationships
Example:
SortedMap
A map that maintains its keys in sorted order:
- Automatic key sorting
- Customizable sort order
- Type-safe values
- Efficient range operations
Example:
Set
Collections of unique values with:
- Set operations (union, intersection)
- Order maintenance (TreeSet)
- Type safety
- Efficient lookups
Example:
DisjointSet
A specialized set implementation for managing non-overlapping groups:
- Efficient union-find operations
- Path compression optimization
- Group membership tracking
- Connected component analysis
HashSet
An unordered set implementation with constant-time operations:
- O(1) add/remove/contains operations
- No order guarantee
- Memory-efficient storage
- High performance for large datasets
TreeSet
An ordered set implementation using a self-balancing tree:
- Maintains elements in sorted order
- O(log n) operations
- Range query support
- Ordered iteration
Matrix
A 2D array implementation with:
- Row and column operations
- Mathematical operations
- Type-safe elements
- Efficient traversal
Example:
Enhanced Array Object
An improved version of PHP's ArrayObject with:
- Type safety for elements
- Event handling for modifications
- Array manipulation (map, filter, reduce)
- Deep cloning and merging
Example:
Advanced Usage
Type Safety
Event Handling
Error Handling
The library throws the following exceptions:
InvalidArgumentException: When type constraints are violatedLogicException: When attempting to modify immutable arrays
