title: Laravel Validation check array size min and max
body: <p>I just need to check in Laravel validation that an array contains minimum 2 values and maximum 4 values. Is there any default validation rule can be used for this ? The <code>size</code> element checks for exact size match and the other rules likes <code>min</code> and <code>max</code> are for strings, digits and file size. </p>
