title: php version upgrade cause an error for old program
body: <p>I just installed xampp, to run some old program (created 2 or more years ago) and I'm getting 3 errors I can't figure out.</p>
  
  <blockquote>
    <ol>
    <li>Strict Standards: Only variables should be passed by reference in C:\xampp\htdocs\2010\web\core\route\route.php on line 117</li>
    </ol>
  </blockquote>
  
  <pre><code>    public function loadClass($address,$ext='') {
          $this-&gt;extname = preg_replace('/_/','/',$address,3);
  line:117&gt;       $this-&gt;classname = end(explode('_',$address)).($e= $ext!='' ? '('.$ext.')' :  '');
          include_once(ROOT_ROUTE.'/'.$this-&gt;extname.'.php');
          $this-&gt;newclass = new $this-&gt;classname;
          return $this-&gt;newclass;
      }
  </code></pre>
  
  <p>the line 117 i can't understand, it is not using passed by reference, why there is a error?</p>
