Undefined index: search in C:\wamp\www\search1 (2).php on line 4 [duplicate]

Question

This is my code:

$button = $_GET ['submit'];
$search = $_GET ['search']; 

if(!$button)
echo "you didn't submit a keyword!";
else

And I'm getting this error:

Undefined index: search in C:\wamp\www\search1 (2).php on line 4

Use isset() before reading an array key in $_GET/$_POST/$_REQUEST.

$button = isset($_GET['submit']) ? $_GET['submit'] : false;
$search = isset($_GET['search']) ? $_GET['search'] : false;
if(!$button) echo "you didn't submit a keyword!";
