If you want to remove "training in india" in your string, better use str_replace like this

$course_name = str_replace('training in india', '', $course_n);

You can simply use str_replace()

$course_name = str_replace("training in india",'',$course_n);

Your example here is incorrect.

Second param in rtrim is not a string, it is character mask.

So, rtrim($s, 'training in india') is equal to rtrim($s, 'traing d').

It's used by filter for trimmed characters.

I believe, you have used some character mask with 'o' character, and it was trimmed as well.

You should to select some other strategy to cut string from the end.
For example:

$str = 'sap bo training in india';
$cut = preg_quote('training in india');
$result = preg_replace("/\s*$cut\$/", '', $str);
var_dump($result); // "sap bo"
