  <p>This is what i have done. I am able to get root element and now i want to go two levels down to grap EventID and OutcomeDateTime.</p>
  
  <p>PHP code</p>
  
  <pre><code>$json_a=json_decode($string,true);
  foreach ($json_a as $root_element =&gt; $childnode) {
      echo($childnode['EventID']);
        echo($childnode['OutcomeDateTime']);
        echo "&lt;br&gt;";
  }
  </code></pre>
  
  <p>If anyone can just give me a way to get two levels down so that i can work on my other scripts. I had posted this question before but i was not welcomed with good responses may be i was not able to express my question in a better way and many thought i am asking for full source code. This time i just need a method to grap child elements.
  THanks</p>
