在php中对包含日期的数组进行排序

我有一个这样的数组，我想按日期对数组进行排序，如何对数组进行排序

Array
(
[0] => 28/02/2016
[1] => 30/01/2016
[2] => 16/02/2016
[3] => 19/02/2016
[4] => 24/02/2016
[5] => 13/02/2016
[6] => 18/02/2016
[7] => 27/02/2016
[8] => 25/02/2016
[9] => 01/02/2016
[10] => 02/02/2016
[11] => 03/02/2016
[12] => 05/02/2016
[13] => 06/02/2016
[14] => 07/02/2016
[15] => 08/02/2016
[16] => 11/02/2016
[17] => 12/02/2016
)

我使用过usort，但它不起作用。我正在编写一个函数并将其转换为STROTIME，但它不起作用。有任何建议。

请尝试以下解决方案：

$array = array
(
    0 => '28/02/2016',
    1 => '30/01/2016',
    2 => '16/02/2016',
    3 => '19/02/2016',
    4 => '24/02/2016',
    5 => '13/02/2016',
    6 => '18/02/2016',
    7 => '27/02/2016',
    8 => '25/02/2016',
    9 => '01/02/2016',
    10 => '02/02/2016',
    11 => '03/02/2016',
    12 => '05/02/2016',
    13 => '06/02/2016',
    14 => '07/02/2016',
    15 => '08/02/2016',
    16 => '11/02/2016',
    17 => '12/02/2016'
);

function sortFunction( $a, $b ) {
    $date1 = DateTime::createFromFormat('d/m/Y', $a);

    $date2 = DateTime::createFromFormat('d/m/Y', $b);
    return $date1->getTimestamp() - $date2->getTimestamp();
}
usort($array, "sortFunction");
print_r($array);

输出

Array
(
    [0] => 30/01/2016
    [1] => 01/02/2016
    [2] => 02/02/2016
    [3] => 03/02/2016
    [4] => 05/02/2016
    [5] => 06/02/2016
    [6] => 07/02/2016
    [7] => 08/02/2016
    [8] => 11/02/2016
    [9] => 12/02/2016
    [10] => 13/02/2016
    [11] => 16/02/2016
    [12] => 18/02/2016
    [13] => 19/02/2016
    [14] => 24/02/2016
    [15] => 25/02/2016
    [16] => 27/02/2016
    [17] => 28/02/2016
)

使用sort（）尝试此操作

---

显示您编写的函数。将

/

替换为

-

可能会解决此问题。检查此选项可能有用@USER3270582将格式更改为

d-m-Y

，这样它就可以像sougata所说的那样通过

strottime

进行调节，并且它可以工作，可能会重复Yes stru replace/with-is workings，谢谢
