将字段的所有值移动到数组

Question

我想将名为CONTENT_VALUE的字段的所有值移动到数组变量。现在我发现错误json_decode（）期望参数1是字符串，给定数组

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    let buttonConnect = UIButton()      
    buttonConnect = UIButton(frame: CGRect(x:0, y:335, width:120, height:40))
    buttonConnect.backgroundColor = UIColor(red: 0.8, green: 0.6, blue: 0.2, alpha: 1.0)
    buttonConnect.setTitle("Connect", forState: .Normal)
    buttonConnect.tag = 3
    buttonConnect.addTarget(self, action: "btnConnectTouched:", forControlEvents: .TouchUpInside)       
    self.view.addSubview(buttonConnect)
}

func btnConnectTouched(sender: UIButton!) {
     print("button connect touched");
}

Answer 1

只需在json_decode函数中将第二个参数设置为true：

//...
$bulk=json_decode($fet_pic['CONTENT_VALUE'], true);
//...

Answer 2

在将JSON字段附加到数组之前解码它：

while( $fet_pic = mysql_fetch_array($albpic) )
    $album[] = json_decode( $fet_pic['CONTENT_VALUE'] );
