title: Does PHPUnit have some inbuilt recursive array comparison function?
body: <p>Some of the testing I will need to do will require comparing a known array with the result I am getting from the functions I will be running.  </p>
  
  <p>For comparing arrays recursively:</p>
  
  <ul>
  <li>Does PHPUnit have an inbuilt function?</li>
  <li>Does someone here have some code they have constructed to share?</li>
  <li>Will this be something I will have to construct on my own?</li>
  </ul>
