Only variables should be assigned by reference using a function

Question

I am using an old version of the Codeigniter framework. With the new php version, I get this error: Only variables should be assigned by reference

I am wondering if this is a safe fix: Change:

  $this->_base_classes =& is_loaded(); 

to

 $assign = is_loaded(); $this->_base_classes =& $assign; 

This is the same?

Please view this URL

You can go to file: system/core/Loader.php then file: system/core/Common.php Line 190 should be:

 function &is_loaded($class = '') 

Answer 2

remove this on line 150 from system/core/Loader.php

$this->_base_classes =& is_loaded(); ..
