Only variables should be assigned by reference with function

Question

I use old version of Codeigniter framework. With new version of php I am gettings this error: Only variables should be assigned by reference

I am wondering if this is safe bugfix: Changing:

 $this->_base_classes =& is_loaded();

to

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

Is that the same?

Answer 1

This is an codeigniter bug in which the old version does not support anymore the mysql.

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

//function is_loaded($class = '') >>> Edit this one like the expression below

  function &is_loaded($class = '')

function &is_loaded($class = '')

After that go to file: application/config/database.php and change the following below:

//$db['default']['dbdriver'] = 'mysql'; >>> Edit this one like the expression below.

$db['default']['dbdriver'] = 'mysqli';

I hope it works
