title: Laravel 5 & validating multiple email addresses in a single field
body: <p>I know in Laravel you can setup validation rules for input fields, for example: </p>
  
  <pre><code>    $return =  [
          'first_name' =&gt; 'required|max:300|min:3',
          'last_name' =&gt; 'required|max:300|min:3',
          'email' =&gt; 'required|email,
      ];
  </code></pre>
  
  <p>Is there a way to easily set this kind of validation for a single field with comma separated email addresses (<code>test@email.com, wibble@test.com</code>) or do I need to manually validate these by splitting them apart and checking each email address individually?</p>
