How to disable PHP Error reporting in CodeIgniter?

Here is the typical structure of new Codeigniter project:

- application/- system/- user_guide/- index.php <- this is the file you need to change

I usually use this code in my CI index.php. Just change local_server_name to the name of your local webserver.

With this code you can deploy your site to your production server without changing index.php each time.

// Domain-based environmentif ($_SERVER['SERVER_NAME'] == 'local_server_name') {    define('ENVIRONMENT', 'development');} else {    define('ENVIRONMENT', 'production');}/* *--------------------------------------------------------------- * ERROR REPORTING *--------------------------------------------------------------- * * Different environments will require different levels of error reporting. * By default development will show errors but testing and live will hide them. */if (defined('ENVIRONMENT')) {    switch (ENVIRONMENT) {        case 'development':            error_reporting(E_ALL);            break;        case 'testing':        case 'production':            error_reporting(0);            ini_set('display_errors', 0);              break;        default:            exit('The application environment is not set correctly.');    }}

Change CI index.php file to:

if ($_SERVER['SERVER_NAME'] == 'local_server_name') {    define('ENVIRONMENT', 'development');} else {    define('ENVIRONMENT', 'production');}if (defined('ENVIRONMENT')){    switch (ENVIRONMENT){        case 'development':            error_reporting(E_ALL);        break;        case 'testing':        case 'production':            error_reporting(0);        break;        default:            exit('The application environment is not set correctly.');    }}

IF PHP errors are off, but any MySQL errors are still going to show, turn these off in the /config/database.php file. Set the db_debug option to false:

$db['default']['db_debug'] = FALSE; 

Also, you can use active_group as development and production to match the environment https://www.codeigniter.com/user_guide/database/configuration.html

$active_group = 'development';$db['development']['hostname'] = 'localhost';$db['development']['username'] = '---';$db['development']['password'] = '---';$db['development']['database'] = '---';$db['development']['dbdriver'] = 'mysql';$db['development']['dbprefix'] = '';$db['development']['pconnect'] = TRUE;$db['development']['db_debug'] = TRUE;$db['development']['cache_on'] = FALSE;$db['development']['cachedir'] = '';$db['development']['char_set'] = 'utf8';$db['development']['dbcollat'] = 'utf8_general_ci';$db['development']['swap_pre'] = '';$db['development']['autoinit'] = TRUE;$db['development']['stricton'] = FALSE;$db['production']['hostname'] = 'localhost';$db['production']['username'] = '---';$db['production']['password'] = '---';$db['production']['database'] = '---';$db['production']['dbdriver'] = 'mysql';$db['production']['dbprefix'] = '';$db['production']['pconnect'] = TRUE;$db['production']['db_debug'] = FALSE;$db['production']['cache_on'] = FALSE;$db['production']['cachedir'] = '';$db['production']['char_set'] = 'utf8';$db['production']['dbcollat'] = 'utf8_general_ci';$db['production']['swap_pre'] = '';$db['production']['autoinit'] = TRUE;$db['production']['stricton'] = FALSE;

i know i am very late but you can just do this : Find below code in index.php file

define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'development');

and replace development with production
