Parse error: syntax error, unexpected ')' in /home/prayqxia/public_html/http://ift.tt/1I1QCox on line 36

I tried to insert this code to my wordpress site, in my theme fuction.php file. that was when I start to experience this problem.

/** * Checks if a particular user has a role. * Returns true if a match was found. * * @param string $role Role name. * @param int $user_id (Optional) The ID of a user. Defaults to the current user. * @return bool */ function appthemes_check_user_role( $role, $user_id = null ) {

if ( is_numeric( $user_id ) )
$user = get_userdata( $user_id );
else
    $user = wp_get_current_user();

if ( empty( $user ) )
return false;

return in_array( $role, (array) $user->roles );

}
