code:

courses.php?search-result=sap+bo+training+in+india

In this code I am fetching data from mysql and now I want to remove training in india with due to this I am using rtrim() function in php like this:

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.

You can simply use str_replace()

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