function Company($Company_Name, $Role) {
    return sprintf("%s %s\r\n", $Company_Name, $Role);
}

// Using ReflectionFunction() over the specified
// function company
$function = new ReflectionFunction('company');

// Calling the invokeArgs() function
$A = $function->invokeArgs(array('GeeksforGeeks',
                 'is a Computer Science Portal.'));
