title: How to read multiple values in a single POST variable
body: <p>I have a POST variable <code>'IMG'</code> that has multiple values like this example:</p>
  <pre><code>IMG=url.com/img1.png|url.com/img2.png|url.com/img3.png&amp;...
  </code></pre>
  <p>So the three URL of the images are separated by <code>|</code> but are in a single <code>POST</code> variable.</p>
  <p>What is the best method to properly read and handle these values?
  I need to have these values as separate variables or as an array to properly handle them.</p>
