title: Simple PHP random array
body: <p>I have a simple array like this:</p>
  
  <pre><code>$input = array('Line1', 'Line2', 'Line3');
  </code></pre>
  
  <p>And want to echo one of the values randomly. I've done this before but can't remember how I did it and all the examples of array_rand seem more complex that what I need.</p>
  
  <p>Can any help? Thanks</p>
