php - 获取数组中的sql数据

Question

我正在尝试创建非常简单的类，我可以在其中从表中检索数据。

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;
    }

}
}

当我调用 $db->getAll('mytable'); 时，它会检索:

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。但我不想自己写。我希望它从列名中获取并放入键值。有简单的方法吗？我可以检索所有字段名称并替换它们，但似乎效率不高。

为什么你还在使用mysql_？它已被弃用。

无论如何，使用mysql_fetch_assoc而不是mysql_fetch_row
