title: How do you eval() a PHP code through multiple levels?
body: <p>I have this code:</p>
  
  <pre><code>$layout_template = template_get("Layout");
  $output_template = template_get("Homepage");
  $box = box("Test","Test","Test");
  eval("\$output = \"$layout_template\";");
  echo $output;
  </code></pre>
  
  <p>In the $template_layout variable is a call for the 
  variable $output_template, so then the script moves onto the $output_template variable</p>
  
  <p>But it doesn't go any further, inside the $output_template is a call to the variable $box, but it doesn't go any further than one level</p>
