Here is the typical structure of new Codeigniter project:

<pre><code>- application/
- system/
- user_guide/
- index.php &lt;- this is the file you need to change
</code></pre>

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.

<pre><code>// Domain-based environment
if ($_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.

 switch (ENVIRONMENT) {
 case 'development':
 error_reporting(E_ALL);

 case 'testing':
 case 'production':

 ini_set('display_errors', 0); 
 break;
 default:
 exit('The application environment is not set correctly.');
 }
}

Change CI index.php file to:

 define('ENVIRONMENT', 'development');

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:

<pre><code>$db['default']['db_debug'] = FALSE;

i know i am very late but you can just do this : Find below code in index.php file
<pre><code>define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'development');

and replace development with production

No need to type a long query to disable error reporting in codeigniter. Use <code>error_reporting(0);</code> in the page to disable displaying errors in that page.
<pre><code>&lt;?php
 error_reporting(0);
?&gt;
</code></pre>

I've read the official <a href="http://ellislab.com/codeigniter/user-guide/general/errors.html">documentation</a> and all they say is that I should have a error_reporting() function located at the top of your main index.php file. But I don't have <code>index.php</code> file in my project. My base controller is called <code>core</code> so to get to main index I go to <code>www.mysite.dom/core/</code>. So I guess this error reporting function should be inside this controller? Then what I would like to know is where should I put it in the controller and what to put inside of it to disable the reporting. Thank you all for help, guess I am missing something :/

How to disable PHP Error reporting in CodeIgniter?

我读过官方的，他们说我应该在你的主index.php文件的顶部有一个error_reporting()函数。，但是我的项目中没有index.php文件。我的基本控制器叫做core，所以为了获得主索引，我转到了www.mysite.dom/core/。所以我猜这个错误报告函数应该在这个控制器内部？然后我想知道的是我应该把...
