Yii2 using array to build activeform - cannot get & echo second array element

Question

I have created and registered a Yii2 component function 'formSchema' which contains the array as such:

class FormSchema extends Component{

  public function formSchema()
  {

    $fields = array(
      ['field' => 'username', 'controltype' => 'textinput'],

      ['field' => 'email', 'controltype' => 'textArea'],
    ); 

     return $fields;
    }
   }
?>

I call the array in the active form, however I cannot get the ['controltype'] using the same successful method as I do to retrieve ['field'] as below. I would like to get that array element however seem unable to get any but the first level element:

<div class="usermanager-form">

<?php $form = ActiveForm::begin(['id'=>$model->formName()]); ?>

<?php

   $fields = $items = Yii::$app->formschema->formSchema();

   foreach($fields as $field)
   {

      $field = $field['field'];

      echo $form->field($model, $field);
    }

?>

You may use array values in this way:

$fields = Yii::$app->formschema->formSchema();
foreach ($fields as $field) {
    echo $form->field($model, $field['field'])->{$field['controltype']}();
}

I am a little stuck working out how to format answer posts correctly, this is my first post, any guidance appreciated. There does not seem to be a HTML editor for comments to answers...

You cannot format code in comments - you may add this as separate answer. Also see stackoverflow.com/help/accepted-answer and stackoverflow.com/help/self-answer
