title: creating link with query string array by yii2
body: <p>In Yii2 I need to create a link to</p>
  
  <p><a href="http://my.site/controller/view?val[]=1&amp;val[]=2&amp;val[]=3" rel="nofollow noreferrer">http://my.site/controller/view?val[]=1&amp;val[]=2&amp;val[]=3</a></p>
  
  <pre><code>Html::a('link',['controller/view','val[]'=&gt;1,'val[]'=&gt;2,'val[]'=&gt;3])
  </code></pre>
  
  <p>obviously it doesn't work. Is there any possible workaround?</p>
