title: how to split arrays inside a big array to fit intersect function?
body: <p>I have the following array that contains other arrays:</p>
  
  <pre><code>$bigArray = [$array_one, $array_two, $array_three,.... ];
  </code></pre>
  
  <p>I want to <code>array_intersect</code> the inner arrays like so:</p>
  
  <pre><code>$intersect = array_intersect($array_one, $array_two, $array_three,....);
  </code></pre>
  
  <p>How do I handle it?</p>
