title: Best way of returning differences of two json files programatically
body: <p>I have two json files and I would like to get a json containing the differences. <strong>It is important</strong> that <strong>only</strong> the actual differences of <strong>content</strong> should be shown, regardless of changing the order of some elements.    </p>
  
  <p>What would be the best way to do that? I am searching for a solution as efficient as possible, since <code>json</code>s may contain lots of data, and users need jobs to be done as quick as possible.</p>
  
  <p>Note: The <code>json</code>s might contain data encoded at different depths. Any programming language is ok, but I would prefer an answer that could easily be implemented in php.</p>
