undefined index: (problem)

[dynamyc]

Hello!
I have a search script and when i run it i receive this
( ! ) Notice: Undefined index: terms in search.php on line 15 and another on line 18
This is line 15 :

$nospaces = substr($_GET,0,4);

and this line 18:

if ($_GET == "") {

I run this on my localhost (WAMP last version)

If the array index “terms” doesn’t exist then this error will occur, what you need to do is the following…

if (isset($_GET) && !empty($_GET)) {

$nospaces = substr($_GET, 0, 4);

} else {

// Show an error message!

}

This will make sure the index exists otherwise it will show an error if you want it to.

@dynamyc, I don’t think such notice is an error in the world of PHP, it’s just a notice.

The simplest way is to ignore NOTICE in PHP:

error_reporting(E_ALL^E_NOTICE);

However, if you need to make it strict, follow @SgtLegend’s way.
