title: PHP explode on second instance of a delimiter
body: <p>I am trying to explode a string using PHP but when only if the second instance of the delimiter is detected before exploding it, for my case i want to explode it after the second space is detected. </p>
  
  <p>My String</p>
  
  <p><code>Apple Green Yellow Four Seven Gray</code></p>
  
  <p>My desire output</p>
  
  <pre><code>Apple Green
  Yellow Four
  Seven Gray
  </code></pre>
  
  <p>My initial code</p>
  
  <pre><code>$string = 'Apple Green Yellow Four Seven Gray';
  $new = explode(' ',$string);
  </code></pre>
  
  <p>How can i achieve this using explode or any separating method with PHP? thanks in advance!</p>
