CodeIgniter error when connecting to any database

Question

I just downloaded a fresh copy of CI from their site(version 3.0.3) and simply configured database and loaded it, but i am having error.

Below is my database configuration in config.php

$db['default'] = array(
'dsn'   => '',
'hostname' => 'localhost',
'username' => 'root',
'password' => '',
'database' => 'shortagesdb',
'dbdriver' => 'mysql',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => TRUE,//(ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE

);

and here is what i am doing in my controller i-e simply loading database

public function index()
{
    $this->load->database();
    $this->load->view('welcome_message');
}

Nothing fancy here and i am getting this exception no matter what

PHP Fatal error:  Call to undefined function mysql_connect() in D:\Projects\ims\system\database\drivers\mysql\mysql_driver.php on line 136

Any help would be highly appreciated

@ChetanAmeta did what you asked and got this error again PHP Fatal error: Call to undefined function mysqli_init() in D:\Projects\ims\system\database\drivers\mysqli\mysqli_driver.php on line 125 — user2539602

Codeigniter 3 won't support MySQL. MySQL is deprecated in version 3.0

Try this

$db['default'] = array(
'dsn'   => '',
'hostname' => 'localhost',
'username' => 'root', # check username
'password' => '', # check password
'database' => 'shortagesdb', # check DB name is correct
'dbdriver' => 'mysqli', # remove mysql
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => (ENVIRONMENT !== 'production'), # remove TRUE,
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE

The problem might be in your php.ini file, go to you php folder and open that file in a text editor. Now find the extensions and uncomment this:

extension=php_mysqli.dll

Also check that you extension path is correctly directed to your ext folder in the php root location.

if are you using php7 make sure you using the php.ini of php 7. /etc/php/7.0/cli
