# Getting Started

## Installation

In your application's folder, run:

```
composer require marquine/php-etl
```

## Database Configuration

If you are working with ETL, you probally need to read and/or write to databases. Currently, we support MySQL, PostgreSQL, SQL Server and SQLite.

These are the configuration parameters for each database driver:

* MySQL

  ```php
  $config = [
    'driver' => 'mysql',
    'host' => 'localhost',
    'port' => '3306',
    'database' => 'database',
    'username' => 'user',
    'password' => 'password',
    'charset' => 'utf8',
    'collation' => 'utf8_unicode_ci',
  ];
  ```
* PostgreSQL

  ```php
  $config = [
    'driver' => 'pgsql',
    'host' => 'localhost',
    'port' => '5432',
    'database' => 'database',
    'username' => 'user',
    'password' => 'password',
    'charset' => 'utf8',
    'schema' => 'public',
  ];
  ```
* SQL Server

  ```php
  $config = [
    'driver' => 'sqlsrv',
    'host' => 'localhost',
    'port' => '1433',
    'database' => 'database',
    'username' => 'user',
    'password' => 'password',
  ];
  ```
* SQLite

  ```php
  $config = [
    'driver' => 'sqlite',
    'database' => '/path/to/database.sqlite',
  ];
  ```

### Adding connections

Adding the default connection:

```php
use Marquine\Etl\Etl;

Etl::service('db')->addConnection($config); // connection name: 'default'
```

You can add more connections passing a name as the second argument to the `addConnection` method:

```php
use Marquine\Etl\Etl;

Etl::service('db')->addConnection($config, 'name');
```

## Laravel Integration

If you are using Laravel 5.5 or greater, the package will automatically register all database connections.

For other versions, you need to add the ServiceProvider to the `providers` array in the `config/app.php` file:

```php
Marquine\Etl\EtlServiceProvider::class,
```
