更改数组键的日期格式

Question

我有这个数组；

Array
(
    [2017-04-01] => 0
    [2017-04-02] => 0
    [2017-04-03] => 0
    [2017-04-04] => 0
    [2017-04-05] => 0
)

如何将日期格式化为这样的内容？

Array
(
    [01-04-2017] => 0
    [02-04-2017] => 0
    [03-04-2017] => 0
    [04-04-2017] => 0
    [05-04-2017] => 0
)

谢谢。

Answer 1

一个简单的

foreach

循环然后转换为格式

d-m-Y

可以做到这一点

$result = [];
foreach ($datas as $key => $value) {
    $date = date('d-m-Y', strtotime($key));
    $result[$date] = $value;
}

print_r($result);
