title: Field validation for phone number in Laravel 5?
body: <p>I have the following array of fields:</p>
  
  <pre><code>$fields = [
      'name'     =&gt; [
          'label' =&gt; 'Company Name' . $req,
  
       ],
       'address1' =&gt; [
       'label' =&gt; 'Address' . $req
       ],
      'address2' =&gt; [
          'label' =&gt; 'Address (Line 2)'
       ],
      'zip'      =&gt; [
          'label' =&gt; 'Zip/Postal Code'
       ],
  
      'phone'   =&gt; [
          'label' =&gt; 'Office Phone',
          'val'   =&gt; dotted($active-&gt;office)
       ],
      [
          'type'  =&gt; 'submit',
          'label' =&gt; "Save",
          'class' =&gt; 'btn btn-primary !important'
      ]
  ];
  </code></pre>
  
  <p>I need to validate the field 'phone' to make sure that it is 10 digits, all numbers. What can I add here to check this here, or should I validate it somewhere else?</p>
