codeigniter error in page source view

I'm working with one array that have 55 elements inside and each one are another array with 17 elements each one.

When I show the array on the screen, nothing wrong happens but when I take a look in the page source, I have 55 x 17 "Severity: Notice" errors with the message "Undefined index".

Does someone know what can be wrong?

If the index really doesn't exist, I couldn't see the array on the screen.

I tested using if ( isset( ) ) { ... }, but still the same.

Codeigniter version: 1.7.2

Browsers tested: firefox, chrome, i开发者_C百科e and safari.

I usually get this errors when I'm trying to echo something that is not defined. It's not an PHP error, only a notice. This is produced by the function error_reporting(); on the main index.php.

If you open this index.php file, you will see:

/*
|---------------------------------------------------------------
| PHP ERROR REPORTING LEVEL
|---------------------------------------------------------------
|
| By default CI runs with error reporting set to ALL.  For security
| reasons you are encouraged to change this when your site goes live.

*/
    error_reporting(E_ALL);

You've two options:

1. Don't print a variable that is not defined.
2. Change the error_reporting(); with a non-notice prints. Like: error_reporting(E_ALL & ~E_NOTICE);.

Wish this helps you!

This has nothing to do with CI or your browser, it is a classic PHP notice.
