Syntax error when creating PHP function

Good day, I have this problem when running a function in PHP, if someone can help me, I thank you in advance

   public function actionIndex()
    {
        // ejecución de la tarea de etl
        $job = new Job();
        Job::start()
        // datos a extraer
        ->extract('table', 'user'); 
        $options = ['columns' => ['user_id','user_name','user_real_name']];        
        [
            'connection' => 'mysql' // Base de datos de donde obtendre los datos, si no viene seteado se utiliza el valor que tiene el campo 'default'
        ],
        // transformacion a aplicar a los datos
        ->transform('trim', ['columns' => ['codigo', 'nombreusuario', 'nombre']])
        // donde cargare los datos
        ->load('table', 'usuario_dimension_wikieam', [
            'connection' => 'pgsql' // Base de datos a donde voy a insertar los datos
        ]);
    }

This is the class where the function is

class EtlController extends Controller
{

    public function actionEtl(){
        return $this->render('index',[]);
    }


    public $file;
    public function init()
    {
        Etl::config([
            'path' => '/path/to/etl/files',

                // Base de datos a utilizar
