This question already has an answer here:

$course_n = $_GET['search-result'];
Through this I can get the value from url i.e. (sap bo training in india) but when I am using rtrim() function it show me only (sap b) but I want (sap bo) and want to remove (training in india).
$course_n = $_GET['search-result'];
$course_name = rtrim($course_n,"training in india");
echo $course_name;
output:
sap b
So, How can I fix this problem ?Please help me.
Thank You

You can simply use str_replace()
$course_name = str_replace("training in india",'',$course_n);
If you want to remove "training in india" in your string, better use str_replace like this
$course_name = str_replace('training in india', '', $course_n);
Your example here is incorrect.
Second param in rtrim is not a string, it is character mask.
So, rtrim($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"
