Question

Array
(
    [0] => Array
        (
            [time_from] => 06:00
            [time] => 06:00-07:00
            [booking_date_from] => 2017-09-19
            [booking_date_to] => 2017-09-19
            [court_price] => 100
            [pricetype] => hour
        )

    [1] => Array
        (
            [time_from] => 06:00
            [time] => 06:00-08:00
            [booking_date_from] => 2017-09-19
            [booking_date_to] => 2017-09-19
            [court_price] => 200
            [pricetype] => hour
        )

    [2] => Array
        (
            [time_from] => 07:00
            [time] => 07:00-09:00
            [booking_date_from] => 2017-09-19
            [booking_date_to] => 2017-09-19
            [court_price] => 200
            [pricetype] => hour
        )

    [3] => Array
        (
            [time_from] => 08:00
            [time] => 08:00-09:00
            [booking_date_from] => 2017-09-20
            [booking_date_to] => 2017-09-20
            [court_price] => 100
            [pricetype] => hour
        )

    [4] => Array
        (
            [time_from] => 11:00
            [time] => 11:00-13:00
            [booking_date_from] => 2017-09-19
            [booking_date_to] => 2017-09-19
            [court_price] => 200
            [pricetype] => hour
        )

)

我的数组是这样的我只是想避免重复的日期重复值我想这样放

Array
(
    [0] => Array
        (

            [time] => 11:00-13:00
            [booking_date_from] => 2017-09-19
            [booking_date_to] => 2017-09-19
            [court_price] => 100
            [pricetype] => hour
        )

    [1] => Array
        (
            [time_from] => 08:00
            [time] => 08:00-09:00
            [booking_date_from] => 2017-09-20
            [booking_date_to] => 2017-09-20
            [court_price] => 100
            [pricetype] => hour
        )
)

我应该怎么做才能得到这样的输出。

Answer 1

您可以尝试使用 array_unique() 函数 here .有了这个，您可以使用 foreach 函数逐一读取所有列表，并从所有数组中获取一个参数，并使用它来匹配 array_unique()。试一试，如果不行请投反对票，我会提供更多解决方案。
