title: PHP - Concatenating two variables
body: <p>I'm a newbie stumped on the following. If I'm including an external file on a page that contains the following variable:</p>
  
  <pre><code>$blurb_78 = "Lorem ipsum dolor.";
  </code></pre>
  
  <p>How can I echo $blurb_78 on the local page?
  (where the <code>78</code> part is a generated article ID set to a variable labeled, <code>$id</code>)</p>
  
  <p>The following doesn't work:</p>
  
  <pre><code>echo $blurb_.$id;
  </code></pre>
  
  <p>Thanks much for your help.</p>
