php Class not working functions

I got some strange problems. Using my class i connecting to mysql, connection is successful but when i call a function its not works. Im using my own error handler and if i got in php some error on this line it using exit; i have used echo before calling function and after page is not killing (it means that php work successful) mysql query i have checked its works too but when im using return 'some text'; its not returning. any suggestions why function is not working?

my class:

<?php
include('../config.php');
include('../chat_error_handler.php');

class Chat {
    private $mysqli;
    var $con;

    //Constructor open db conn
    function __construct() {
        $this->mysqli = new mysqli('localhost', 'root', '', 'test');
    }

    //destructor close db conn
    function __destruct() {
        $this->mysqli->close();
    }

    public function postNewMessage($user_name, $message, $color, $room_id) {
        $user_name = $this->mysqli->real_escape_string($user_name);
        $message = $this->mysqli->real_escape_string($message);
        $color = $this->mysqli->real_escape_string($color);
        $room_id = $this->mysqli->real_escape_string($room_id);
        $query = 'INSERT INTO chat (posted_on, account, message, color, room_id)' .
        ' VALUES (NOW(), "'.$user_name.'", "'.$message.'", "'.$color.'", "'. $room_id .'")';
        $result = $this->mysqli->query($query);
        return 'Pranesimas';
        $result->close();
    }

My php im using to debug:

<?php
include('core/chat.class.php');
include('chat_error_handler.php');
$chat = new Chat();
$message = 'testas';
echo $message.'<br/>';
$chat->postNewMessage('testing', $message, '#000000', 1);
echo '<br/>'.$message;
?>

                 '". $message ."', 
                 '". $color ."', 
                 '". $room_id ."' )";

    $result = $this->mysqli->query($query);

About 'var' in PHP5 and upper. It's for declaring class member variables in PHP4, and is no longer needed. It will work in PHP5, but will raise an E_STRICT warning in PHP from version 5.0.0 up to version 5.1.2, as of which it has been deprecated.

UPDATE:

public function postNewMessage($user_name, $message, $color, $room_id) {
        return 'Pranesimas1';
        $user_name = $this->mysqli->real_escape_string($user_name);
        $message = $this->mysqli->real_escape_string($message);
        $color = $this->mysqli->real_escape_string($color);
        return 'Pranesimas2';
        $room_id = $this->mysqli->real_escape_string($room_id);
        $query = 'INSERT INTO chat (posted_on, account, message, color, room_id)' .
        ' VALUES (NOW(), "'.$user_name.'", "'.$message.'", "'.$color.', "'. $room_id .'")';
        $result = $this->mysqli->query($query);
        return 'Pranesimas';
        $result->close();
    }

Try add return step by step for detect where is problem and let me know about result.
