Se può servire per far capire meglio questo è lo script php che uso per questi test...

Codice PHP:

<?php    

    $db_host = 'localhost:8889';
    $db_user = 'root';
    $db_pass = 'root';
    $db_name = 'test';

    $db = mysql_connect($db_host, $db_user, $db_pass);
    mysql_select_db($db_name, $db);

    function strip_magic($value) {

        $value = (get_magic_quotes_gpc()) ? stripslashes($value) : $value;
        return $value;

    }

    if (isset($_POST['vars'])) {

    $var_0 = strip_magic($_POST['vars']);
    $val_0 = mysql_real_escape_string($var_0, $db);

                    $query = "INSERT INTO test (testo) VALUES ('$val_0')";

                    $data = mysql_query($query, $db);
                    $result = mysql_affected_rows();

                    if ($result === 1) {

                    $query_bis = "SELECT * FROM test ORDER by id ASC";

                    $data_bis = mysql_query($query_bis, $db);

                        if (mysql_num_rows($data_bis) == 0) {

                            echo '&esito=NO';
                            exit;

                        } else {

                            echo '&esito=OK';

                            class oData {

                                var $id, $testo;

                                    function oData($id, $testo) {

                                        $this->id = $id;
                                        $this->testo = $testo;

                                    }

                            }

                            $array = array();
                            $a = 0;

                            while ($row = mysql_fetch_assoc($data_bis)) {

                            $array[] = new oData($row['id'], $row['testo']);

                            $a++;

                            }
                            
                            echo '&output='. urlencode(serialize($array));
                            mysql_close($db);

                        }


                    } else {

                        echo '&esito=NO';

                    }

    }
