檢索數組中的sql數據

Question

我試圖做出非常簡單的類，我可以從表中檢索數據。

class dbCore{ 
    private $username; 
    private $password; 
    private $database; 
    private $serverAddress; 
private function createConnection(){ 
    return mysql_connect($this->serverAddress, $this->username, $this->password); 
} 

public function __construct($db=array()){ 
    $this->username = $db['username']; 
    $this->password = $db['password']; 
    $this->database = $db['database']; 
    $this->serverAddress = $db['serverAddress']; 
} 

public function checkConnection(){ 
    $connection = $this->createConnection(); 
    if($connection) 
     mysql_close($connection); 
    return !!$connection; 
} 

public function getAll($tableName){ 
    $data=array(); 
    $connection = $this->createConnection(); 
    $sql = "SELECT * FROM " . $tableName; 
    if ($connection){ 
     mysql_select_db($this->database); 
     $result=mysql_query($sql, $connection); 
     while ($row = mysql_fetch_row($result)) { 
      array_push($data,$row); 
     } 
     return $data; 
    }else{ 
     return false; 
    } 

} 
} 

當我打電話$db->getAll('mytable');它檢索：

Array 
(
    [0] => Array 
     (
      [0] => 1 
      [1] => Riga 
      [2] => Liepaja 
      [3] => 2014-11-20 
      [4] => 2014-11-08 
      [5] => 4 
     ) 

    [1] => Array 
     (
      [0] => 2 
      [1] => Riga 
      [2] => Liepaja 
      [3] => 2014-11-19 
      [4] => 2014-11-09 
      [5] => 3 
     ) 

) 

但我希望它是id => 1, city => Riga等，但我不想把它寫自己。我希望它能夠從列名中提取關鍵值。有沒有簡單的方法來做到這一點？我可以檢索所有字段名稱並替換它們，但似乎效率不高。

你爲什麼還在使用mysql_？它已被棄用。

無論如何，使用mysql_fetch_rowmysql_fetch_assoc代替
