title: Laravel rule validation for numbers
body: <p>I have the following rules :</p>
  <pre><code>'Fno' =&gt; 'digits:10'
  'Lno' =&gt; 'min:2|max5'  // this seems invalid
  </code></pre>
  <p>But how to have the rule that</p>
  <p>Fno should be a digit with minimum 2 digits to maximum 5 digits and</p>
  <p>Lno should be a digit only with min 2 digits</p>
