Check if the $_GET['id'] is set
if(isset($_GET['id'])) {
$query="delete from book where b_id =".$_GET['id'];
}
Undefined index means that you are trying to access data in array that doesn't exist.

You can post your own question about your problem.

When you call the $_GET super global variable it retrieves variables from the url of the page (like anything after the ? located after the page name.) You need to make sure that there is something that says id=someValue. If not it will not work
