能否按时间排序？

Answer 1

python3

>>> import time
>>> t=[('November 11, 2016','%B %d, %Y'),
       ('31 Oct 2016','%d %b %Y'),
       ('2016-01-11','%Y-%m-%d'),
       ('07 Nov 2016','%d %b %Y'),]
>>> t.sort(key=lambda d:time.mktime(time.strptime(d[0],d[1])))
>>> from pprint import pprint as pp
>>> pp(t)
[('2016-01-11', '%Y-%m-%d'),
 ('31 Oct 2016', '%d %b %Y'),
 ('07 Nov 2016', '%d %b %Y'),
 ('November 11, 2016', '%B %d, %Y')]

Answer 2

$date = [
    'November 11, 2016',
    '31 Oct 2016',
    '2016-01-11',
    '07 Nov 2016'
];

usort($date, function($a, $b){
    $a = strtotime($a);
    $b = strtotime($b);
    if ($a == $b) {
        return 0;
    }
    return ($a > $b) ? 1 : -1;
});

php

composer install Carbon

use Carbon\Carbon;

$date = [
    new Carbon('November 11, 2016', 'Asia/Shanghai'),
    new Carbon('31 Oct 2016', 'Asia/Shanghai'),
    new Carbon('2016-01-11', 'Asia/Shanghai'),
    new Carbon('07 Nov 2016', 'Asia/Shanghai'),
];

for ($i = 0; $i < count($date); $i++) {
    for ($j = 0; $j < $i; $j++) {
        if ($date[$j]->lt($date[$i]) {
            $tmp = $date[$j];
            $date[$j] = $date[$i];
            $date[$i] = $tmp;
        }
    }
}
