Question

我正在创建一个这样的数组：

$result[$buyid.'_'.$freeid] = array(
    'itemquantity' => $v,
    'buyproduct' => $_POST['buyproduct'][$k],
    'buyproductid' => $buyid, 
    'freequantity' => $_POST['freequantity'][$k],
    'freeproduct' => $_POST['freeproduct'][$k],
    'freeproductid' => $freeid, 
);

哪个输出我的数组：

Array(
[53_53] => Array
    (
        [itemquantity] => 5
        [buyproduct] => 
        [buyproductid] => 53
        [freequantity] => 1
        [freeproduct] => 
        [freeproductid] => 53
    )

[53_38] => Array
    (
        [itemquantity] => 2
        [buyproduct] => 
        [buyproductid] => 53
        [freequantity] => 1
        [freeproduct] => 
        [freeproductid] => 38
    )

[31_31] => Array
    (
        [itemquantity] => 5
        [buyproduct] => 
        [buyproductid] => 31
        [freequantity] => 1
        [freeproduct] => 
        [freeproductid] => 31
    )

）

我想以稍微不同的方式存储我的数据。我想基于＆＃34; buyproductid＆＃34;存储它。因此，如果有多个＆＃34; buyproductid＆＃34;它创建了一个子数组。像这样：

Array(
[53] => Array(
     [53] => Array(
        [itemquantity] => 5
        [buyproduct] => 
        [buyproductid] => 53
        [freequantity] => 1
        [freeproduct] => 
        [freeproductid] => 53
    ),
    [38] => Array(
        [itemquantity] => 5
        [buyproduct] => 
        [buyproductid] => 53
        [freequantity] => 1
        [freeproduct] => 
        [freeproductid] => 53
    )

），

[31] => Array(
    [31] => Array(
        [itemquantity] => 5
        [buyproduct] => 
        [buyproductid] => 31
        [freequantity] => 1
        [freeproduct] => 
        [freeproductid] => 31
    )

 )

实现这一目标的最佳方法是什么？

Answer 1

您只需稍微改变一下分配语法：

$result[$buyid][$freeid] = array(
    'itemquantity' => $v,
    'buyproduct' => $_POST['buyproduct'][$k],
    'buyproductid' => $buyid, 
    'freequantity' => $_POST['freequantity'][$k],
    'freeproduct' => $_POST['freeproduct'][$k],
    'freeproductid' => $freeid, 
);

Answer 2

只需将其更改为：

    Timer t=new Timer();
    TimerTask task=new TimerTask() {
        @Override
        public void run() {
          button.setText("");//Example
        }
    };
    t.scheduleAtFixedRate(task,0,3000);//3 seconds
