如何在php中检查数组中的重复值

我有这样一个数组：

     Array(
        [0] => Array
            (
                [timesheet_id] => 27
                [fullname] => Technician Nguyen
                [division_id] => 1
                [date_ts] => Thursday
                [user_id] => 3
                [from_time] => 2
                [to_time] => 11.3
                [from_time_ot] => 0
                [to_time_ot] => 6
                [from_time_wt] => 8.3
                [to_time_wt] => 17.3
                [time] => 9.3
                [OT_table] => 2
            )

        [1] => Array
            (
                [timesheet_id] => 27
                [fullname] => Technician Nguyen
                [division_id] => 1
                [date_ts] => Thursday
                [user_id] => 3
                [from_time] => 2
                [to_time] => 11.3
                [from_time_ot] => 6
                [to_time_ot] => 8.3
                [from_time_wt] => 8.3
                [to_time_wt] => 17.3
                [time] => 9.3
                [OT_table] => 1.5
            )

        [2] => Array
            (
                [timesheet_id] => 32
                [fullname] => Technician Nguyen
                [division_id] => 1
                [date_ts] => Friday
                [user_id] => 3
                [from_time] => 17.3
                [to_time] => 22.3
                [from_time_ot] => 17.3
                [to_time_ot] => 23.5
                [from_time_wt] => 8.3
                [to_time_wt] => 17.3
                [time] => 5
                [OT_table] => 1.5
            ))

我希望以这种方式使用相同的数组，这意味着它将检查是否在同一天，然后检查时间段（本例的重点是“从时间到时间”），并输出“从时间到结束时间”的时间范围，如下面的数组所示

  Array(
        [0] => Array
            (
                [timesheet_id] => 27
                [fullname] => Technician Nguyen
                [division_id] => 1
                [date_ts] => Thursday
                [user_id] => 3
                [from_time] => 2
                [to_time] => 11.3
                [from_time_ot] => 0
                [to_time_ot] => 8.3
                [from_time_wt] => 8.3
                [to_time_wt] => 17.3
                [time] => 9.3
                [OT_table] => 2
            )

        [1] => Array
            (
                [timesheet_id] => 32
                [fullname] => Technician Nguyen
                [division_id] => 1
                [date_ts] => Friday
                [user_id] => 3
                [from_time] => 17.3
                [to_time] => 22.3
                [from_time_ot] => 17.3
                [to_time_ot] => 23.5
                [from_time_wt] => 8.3
                [to_time_wt] => 17.3
                [time] => 5
                [OT_table] => 1.5
            ))

有人可以帮我吗？

这只是一个解决方案，您可以根据您的规范进行修改

这只是一个简单的问题

输出：

Array
(
    [0] => Array
        (
            [timesheet_id] => 27
            [fullname] => Technician Nguyen
            [division_id] => 1
            [date_ts] => Thursday
            [user_id] => 3
            [from_time] => 2
            [to_time] => 11.3
            [from_time_ot] => 0
            [to_time_ot] => 6
            [from_time_wt] => 8.3
            [to_time_wt] => 17.3
            [time] => 9.3
            [OT_table] => 2
        )

    [1] => Array
        (
            [timesheet_id] => 32
            [fullname] => Technician Nguyen
            [division_id] => 1
            [date_ts] => Friday
            [user_id] => 3
            [from_time] => 17.3
            [to_time] => 22.3
            [from_time_ot] => 17.3
            [to_time_ot] => 23.5
            [from_time_wt] => 8.3
            [to_time_wt] => 17.3
            [time] => 5
            [OT_table] => 1.5
        )

下面的代码将在数组上循环并构建一个不包含重复元素的新数组

<?php

$array = [['a', 'b'], ['a', 'b'], ['q', 'a']];

$results = [];
for ($i = 0; $i < count($array); $i++) {
    for ($j = 0; $j < count($array); $j++) {
        if ($i === $j) {
            continue;
        }

        if ($array[$i] !== $array[$j] && !in_array($array[$i], $results)) {
            $results[] = $array[$i];
        }
    }
}

var_dump($results); //output [['a', 'b'], ['q', 'a']]

以及您尝试过的内容。如果在第1个from=0到=6，第2个from=10到12，该怎么办？或者在第一个from=0到=14之间，在第二个from=10到12之间？那么其他元素怎么办呢？
foreach
和
if
将帮助你。准确地检查这篇文章，我想计算总的正常工作时间：-如果在第一个从=0到=6，在第二个从=10到12：也应该检查工作时间，如果工作时间从8h30到17h30，输出为：实际时间也取决于8h30-17h30的工作时间，过滤时间为：10-12，总小时数为：2小时。
<?php

$array = [['a', 'b'], ['a', 'b'], ['q', 'a']];

$results = [];
for ($i = 0; $i < count($array); $i++) {
    for ($j = 0; $j < count($array); $j++) {
        if ($i === $j) {
            continue;
        }

        if ($array[$i] !== $array[$j] && !in_array($array[$i], $results)) {
            $results[] = $array[$i];
        }
    }
}

var_dump($results); //output [['a', 'b'], ['q', 'a']]
