Codeigniter default controller not working in PHP Version 5.6.15

Codeigniter controller will not work if we update your xampp version to v3.2.2. Or in other case if you upgrade the php version to 5.6+

in some cases, in the autoload.php in the config folder

$autoload[‘libraries’] = array(‘form_validation’,’session’,’database’);

if we remove database from the array codeigniter controller will work.

So solution to work this controller in the codeigniter is change dbdriver from mysql to mysqli

$db[‘default’][‘dbdriver’] = ‘mysqli’;
