## Configuration options

All options are in the config parameter `phinx` specified as an array (instead of the `phinx_path` variable).
All parameters are *optional*, but you can specify them with a dictionary (to change all parameters)
or by deployer dot notation (to change one option).

### Phinx params

- `phinx.environment`
- `phinx.date`
- `phinx.configuration` N.B. current directory is the project directory
- `phinx.target`
- `phinx.seed`
- `phinx.parser`
- `phinx.remove-all` (pass empty string as value)

### Phinx path params

- `phinx_path` Specify phinx path (by default phinx is searched for in $PATH, ./vendor/bin and ~/.composer/vendor/bin)

### Example of usage

```php
$phinx_env_vars = [
  'environment' => 'development',
  'configuration' => './migration/.phinx.yml',
  'target' => '20120103083322',
  'remove-all' => '',
];

set('phinx_path', '/usr/local/phinx/bin/phinx');
set('phinx', $phinx_env_vars);

after('cleanup', 'phinx:migrate');

// or set it for a specific server
host('dev')
    ->user('user')
    ->set('deploy_path', '/var/www')
    ->set('phinx', $phinx_env_vars)
    ->set('phinx_path', '');
```

## Suggested Usage

You can run all tasks before or after any
tasks (but you need to specify external configs for phinx).
If you use internal configs (which are in your project) you need
to run it after the `deploy:update_code` task is completed.
