嗨，我想排序数组谁能告诉我这里是数组。我想按日期排序你可以看到这里有data

2015-05-20

2015-06-06

Array ( [1] => Array ( [schedule] => WEEKENDS [title] => 2015-05-20 [track] => 6:00 Pm - 9:20 Pm [days] => May 20, 21, 27, 28 June 3, 4 ) [2] => Array ( [schedule] => WEEKENDS [title] => 2015-05-23 [track] => 9:00 Am - 2:30 Pm [days] => May 23, 24 & May 30, 31 ) [3] => Array ( [schedule] => WEEKENDS [title] => 2015-06-6 [track] => Timing will posted soon... [days] => June 06, 07 & June 13, 14 ) ) Array ( [0] => Array ( [schedule] => EVENINGS [title] => 2015-05-16 [track] => 9:00am
- 2:30pm [days] => May 16, 17, 18 & 19 ) ) Array ( [0] => Array ( [schedule] => EVENINGS [title] => 2015-05-16 [track] => 9:00am - 2:30pm [days] => May 16, 17, 18 & 19 ) [2] => Array ( [schedule] => WEEKENDS [title] => 2015-05-25 [track] => 9:00am - 2:30pm [days] => May 16, 17, 18 & 19 ) ) Array ( [0] => Array ( [schedule] => WEEKENDS [title] => 2015-06-30 [track] => 10:00am - 12:30pm [days] => June 2,4 ) ) Array ( [0] => Array ( [schedule] => EVENINGS [title] => 2015-05-17 [track] => 9:00am - 2:30pm [days] => June 2,4,5,8 ) ) Array ( [0] => Array ( [schedule] => 4DAYS [title] => 2015-05-18 [track] => 9:00am - 2:30pm [days] => May 16, 17, 18 & 19 ) )

您可以像这样创建自己的排序函数。

根据"title"键的值进行排序。

$array = array(
    array("title" => "2015-05-20",
        "schedule" => "WEEKENDS"
    ),
    array("title" => "2015-05-16",
        "schedule" => "WEEKENDS"
    )
);
function sortByTitle($a, $b) {
    return $a['title'] - $b['title'];
}
usort($array , 'sortByTitle');
print_r($array);

的回报:

Array
(
    [0] => Array
        (
            [title] => 2015-05-16
            [schedule] => WEEKENDS
        )
    [1] => Array
        (
            [title] => 2015-05-20
            [schedule] => WEEKENDS
        )
)
