如何动态删除多维数组中的键

Question

我必须过滤此数组以仅查看将来的项目。 如何取消设置timeEnd已过期的项目？ 即当我在17:00调用这个数组时，只剩下数组[2]。

阵 （     [0] =＆gt;排列         （             [id] =＆gt; 3034             [date] =＆gt; 28-09-2016             [timeStart] =＆gt; 08:30             [timeEnd] =＆gt; 09:30             [描述] =＆gt; USER_A             [locationId] =＆gt; 1             [roomId] =＆gt; 8             [relationId] =＆gt; 104         ）

[1] => Array
    (
        [id] => 2524
        [date] => 28-09-2016
        [timeStart] => 08:30
        [timeEnd] => 12:00
        [description] => User_B
        [locationId] => 1
        [roomId] => 5
        [relationId] => 86
    )

[2] => Array
    (
        [id] => 2533
        [date] => 28-09-2016
        [timeStart] => 09:00
        [timeEnd] => 18:00
        [description] => User_C
        [locationId] => 1
        [roomId] => 4
        [relationId] => 31
    )

）

Answer 1

foreach ($reservations as $key=>$reservation) {
    $expireDate = $reservation['date'].' '.$reservation['timeEnd'];
    if (strtotime($expireDate) <= strtotime('now')){
        unset($reservations[$key]);
    }
}
