需要从Query中获取所有结果并将它们放入数组中

Question

我试图让这段代码返回一个包含查询结果的数组。但它返回的数组总是空的，但我没有收到任何错误，所以我完全失去了它。

    function selectAll()
{

    print $sql = "SELECT id FROM user;";
    $result = $this->database->query($sql);
    $result = $this->database->result;
    print $result;
    while ($array_fila = mysqli_fetch_array($result)) {
        $this->setId($array_fila["id"]);
        $this->select($this->getid());
        $array_users[] = clone $this;
    }

    return $array_users;


}

我使用的班级数据库是以下

<?php



 class Database
 { // Class : begin

 var $host;         //Hostname, Server
 var $password;     //Passwort mysql
 var $user;         //User mysql
 var $database;     //Datenbankname mysql
 var $link;
 var $query;
 var $result;
 var $rows;

 function Database()
 { // Method : begin
 //Konstruktor



 // ********** DIESE WERTE ANPASSEN **************
 // ********** ADJUST THESE VALUES HERE **********

  $this->host = "127.0.0.1";                  //          <<---------
  $this->password = "eldiego123";           //          <<---------
  $this->user = "root";                   //          <<---------
  $this->database = "wargame";           //          <<---------
  $this->rows = 0;

 // **********************************************
 // **********************************************



 } // Method : end

 function OpenLink()
 { // Method : begin
  $this->link = @mysql_connect($this->host,$this->user,$this->password) or die (print "Class Database: Error while connecting to DB (link)");
 } // Method : end

 function SelectDB()
 { // Method : begin

 @mysql_select_db($this->database,$this->link) or die (print "Class Database: Error while selecting DB");

 } // Method : end

 function CloseDB()
 { // Method : begin
 mysql_close($this->link);
 } // Method : end

 function Query($query)
 { // Method : begin
 $this->OpenLink();
 $this->SelectDB();
 $this->query = $query;
 $this->result = mysqli_query($query,$this->link) or die (print "Class Database: Error while executing Query");

// $rows=mysql_affected_rows();

if(ereg("SELECT",$query))
{
 $this->rows = mysql_num_rows($this->result);
}

 $this->CloseDB();
 } // Method : end  

 } // Class : end

?>

提前致谢！
