title: PHP include statement containing echoed PHP variable
body: <p>I have the required ID variable from this, (there are 1-6 possible values):</p>
  
  <pre><code>$new_product['ID'] =$row[2];
  </code></pre>
  
  <p>What I need is to echo a separate 'php-include' depending on this variable, so something like: </p>
  
  <pre><code>&lt;?php include 'includes/size/prod/echo $row[2].php'; ?&gt;
  </code></pre>
  
  <p>which would display, includes/size/prod/1.php, includes/size/prod/2.php etc </p>
  
  <p>I don't understand how to phrase the 'echo' within the php.</p>
