重命名数组组名

Question

我想更改数组 [0]、[1] 等中的数字 老实说，我也不知道他们的名字，但我在他们之后做了箭头

Array
(
    [user_id] => 1
    [0] => Array  # <----- this [0]
        (
            [prod] => 
        )

    [1] => Array # <----- this [1]
        (
            [item] => 1
            [place] => 2
            [holder] => 2
            [type] => 1
            [amount] => 1
            [sellprice] => 13000.00
            [buyprice] => 12000.00
            [notification] => 16
        )
)

想要的结果：

Array
(
    [user_id] => 1
    ['Some Title'] => Array  # <----- this [0]
        (
            [prod] => 
        )

    ['Title'] => Array # <----- this [1]
        (
            [item] => 1
            [place] => 2
            [holder] => 2
            [type] => 1
            [amount] => 1
            [sellprice] => 13000.00
            [buyprice] => 12000.00
            [notification] => 16
        )
)

我想用一些标题替换那些 [0] 和 [1]

这个代码是用 array_push 生成的

Answer 1

$arr = array(); // your array
// your array push code goes here
    $arr['Title'] = $arr[0];
    $arr['Title 2'] = $arr[1];
    unset($arr[0]);
    unset($arr[1]);
