title: fzaninotto/faker Can you set random $count quantity of randomElements?
body: <p>I am using <a href="https://github.com/fzaninotto/Faker" rel="nofollow noreferrer">this package</a> to seed test data in my Laravel project.</p>
  
  <p>For on field I am using this;</p>
  
  <pre><code>randomElements($array = array ('a','b','c'), $count = 1) // array('c')
  </code></pre>
  
  <p>My question is 2 parts;</p>
  
  <p>a) can you make the $count value random?  For example between 1-3.</p>
  
  <p>b) I am using json_encode to avoid Array to string conversion but now values are being stored with ["example1", "example2"], how do I remove the [""]?</p>
  
  <p>I understand storing arrays is not ideal but development has gone too far down this road.</p>
  
  <p>Thanks!</p>
