The PHP function rtrim is used to remove white space from the end of the string.

Let's check the following example to understand how this function actually works

     <?php
        $string = 'Welcome to America     ';
        echo strlen($string); // Outputs: 23
        $rtrim_str = rtrim($string);
        echo strlen($rtrim_str); // Outputs: 18
    ?>
