title: Variable won't echo in string
body: <p>I'm trying to echo the variable <code>$theurl</code> inside of <code>$image_all</code> but it's not working.</p>
  
  <pre><code>$theurl = OF_DIRECTORY;
  $image_all =  $theurl.$image_path;
  </code></pre>
  
  <p>This should be simple, right? It's only showing what <code>$image_path</code> equals, even though it will echo <code>$theurl</code> if I simply do <code>&lt;?php echo $theurl; ?&gt;</code>.</p>
  
  <p>What am I missing?</p>
