title: Getting first two words from string in php
body: <p>I have string like:</p>
  
  <pre><code>$message="AB 1234 Hello, how are you?
  </code></pre>
  
  <p>I want to get like this:</p>
  
  <pre><code>$message[0] = AB
  $message[1] = 1234
  $message[2] = Hello, how are you?
  </code></pre>
  
  <p>Please don't suggest substr function because length of first two words may vary but they will have spaces in between.
  Any other suggestion?</p>
