**Note:** This package is framework-agnostic and only depends on `connection-contracts` and Hyperf. The framework should ensure `$_ENV` is populated before using this package.

Usage
-----

[](#usage)

### Using the Real Implementation

[](#using-the-real-implementation)

#### MySQL (Default)

[](#mysql-default)

```
use Gemvc\Database\Connection\OpenSwoole\SwooleConnection;

// Set environment variables (or use defaults)
$_ENV['DB_DRIVER'] = 'mysql';
$_ENV['DB_HOST'] = 'db';
$_ENV['DB_NAME'] = 'my_database';
$_ENV['DB_USER'] = 'my_user';
$_ENV['DB_PASSWORD'] = 'my_password';
$_ENV['MIN_DB_CONNECTION_POOL'] = '8';
$_ENV['MAX_DB_CONNECTION_POOL'] = '16';

// Get singleton instance (creates connection pool)
$manager = SwooleConnection::getInstance();

// Get connection from pool (real implementation - connection pooling)
$connection = $manager->getConnection();

// Get underlying PDO instance
$pdo = $connection->getConnection();

// Use PDO directly
$stmt = $pdo->prepare("SELECT * FROM users");
$stmt->execute();

// Or use connection interface methods
$connection->beginTransaction();
$connection->commit();

// Release connection back to pool
$manager->releaseConnection($connection);
```

#### PostgreSQL

[](#postgresql)

```
use Gemvc\Database\Connection\OpenSwoole\SwooleConnection;

// Set environment for PostgreSQL
$_ENV['DB_DRIVER'] = 'pgsql';
$_ENV['DB_HOST'] = 'postgres';
$_ENV['DB_NAME'] = 'my_database';
$_ENV['DB_USER'] = 'my_user';
$_ENV['DB_PASSWORD'] = 'my_password';

// Get connection
$manager = SwooleConnection::getInstance();
$connection = $manager->getConnection();
$pdo = $connection->getConnection();

// Use PostgreSQL connection
$pdo->exec('SELECT * FROM users');
```

### Using the Adapter

[](#using-the-adapter)

```
use Gemvc\Database\Connection\OpenSwoole\SwooleConnectionAdapter;
use Hyperf\DbConnection\Connection;

// Get Hyperf Connection from pool (or create manually)
$hyperfConnection = $pool->get();

// Wrap in adapter for contracts
$adapter = new SwooleConnectionAdapter($hyperfConnection);

// Now implements ConnectionInterface
$adapter->beginTransaction();
$adapter->commit();
```

Architecture
------------

[](#architecture)

This package provides **two components** that work together with `connection-contracts`:

### 1. `SwooleConnection` - Real Implementation

[](#1-swooleconnection---real-implementation)

**Creates actual connection pools:**

- Creates: Hyperf connection pools - **REAL IMPLEMENTATION**
- Implements: `ConnectionManagerInterface` (from `connection-contracts` package)
- Manages connection pool lifecycle
- Handles configuration from environment variables
- Returns: `ConnectionInterface` (wrapped Hyperf Connection via `SwooleConnectionAdapter`)
- **True connection pooling** (not simple caching)
- No framework dependencies - reads `$_ENV` directly

**Database Driver Support:**

- **MySQL** (default): Primary driver with optimizations (charset, collation, strict mode)
- **PostgreSQL**: Supported via standard PDO DSN format
- **Other PDO drivers**: Via standard DSN format

**Configuration Methods:**

1. **Environment Variables** (default): Reads from `$_ENV`

**Environment Variables:**

- `DB_DRIVER` - Database driver (default: `mysql`, supports: `mysql`, `pgsql`, etc.)
- `DB_HOST` - Database host (default: `db` in Swoole, `localhost` in CLI)
- `DB_HOST_CLI_DEV` - Database host for CLI context (default: `localhost`)
- `DB_PORT` - Database port (default: `3306`)
- `DB_NAME` - Database name (default: `gemvc_db`)
- `DB_USER` - Database username (default: `root`)
- `DB_PASSWORD` - Database password (default: empty)
- `DB_CHARSET` - Database charset (default: `utf8mb4`, MySQL only)
- `DB_COLLATION` - Database collation (default: `utf8mb4_unicode_ci`, MySQL only)
- `MIN_DB_CONNECTION_POOL` - Minimum pool size (default: `8`)
- `MAX_DB_CONNECTION_POOL` - Maximum pool size (default: `16`)
- `DB_CONNECTION_TIME_OUT` - Connection timeout in seconds (default: `10.0`)
- `DB_CONNECTION_EXPIER_TIME` - Wait timeout in seconds (default: `2.0`)
- `DB_HEARTBEAT` - Heartbeat interval (default: `-1`, disabled)
- `DB_CONNECTION_MAX_AGE` - Max idle time in seconds (default: `60.0`)
- `APP_ENV` - Application environment (optional, used for dev logging)

### 2. `SwooleConnectionAdapter` - Adapter

[](#2-swooleconnectionadapter---adapter)

**Wraps existing Hyperf Connection instances:**

- Wraps: Hyperf Connection instances (from connection pool)
- Implements: `ConnectionInterface` (from `connection-contracts` package)
- Provides transaction management (on Connection, not Manager)
- Error handling and state tracking
- Used by: `SwooleConnection` to wrap Hyperf connections

### Complete Flow

[](#complete-flow)

```
Application/Framework:
  SwooleConnection::getInstance()
    └─> Returns: SwooleConnection (singleton)
        └─> getConnection() gets from: Hyperf Pool → Connection  ← REAL IMPLEMENTATION (POOLING)
            └─> Wraps Hyperf Connection with: SwooleConnectionAdapter
                └─> Returns: ConnectionInterface

Package Structure:
  SwooleConnection (ConnectionManagerInterface)
    └─> Uses: Hyperf PoolFactory → Pool → Connection
    └─> Wraps with: SwooleConnectionAdapter
        └─> Returns: ConnectionInterface

Contracts Package:
  ConnectionManagerInterface (from connection-contracts)
    └─> Implemented by: SwooleConnection
