Php 检查多维数组中的重复结果

我有一个多维数组，我需要交叉检查它是否有重复的结果，如果它们是重复的，请删除带有重复结果的数组。我需要检查3把钥匙是否重复；号码，出发和到达。下面是一个示例阵列，其中第三个阵列是重复的，需要删除：

[Cars] => Array
    (
        [0] => Array
            (
                [cartype] => car1
                [number] => 123
                [craft] => 456
                [departure] => GHY
                [departtime] => 20:25
                [arrival] => PUI
                [arrivetime] => 22:50
            )

        [1] => Array
            (
                [cartype] => car2
                [number] => 567
                [craft] => 890
                [departure] => LHY
                [departtime] => 16:25
                [arrival] => PGY
                [arrivetime] => 23:50
            )
        [2] => Array
            (
                [cartype] => car2
                [number] => 567
                [craft] => 890
                [departure] => LHY
                [departtime] => 16:25
                [arrival] => PGY
                [arrivetime] => 23:50
            )

    )

我真的很感谢你的帮助

谢谢，

使用

in_array

函数和自定义

$hash\u map

容器的解决方案（每个条目由

编号

、

出发

和

到达

键值组成）：

尝试以下操作以完全删除相同的重复子阵列

$arr = [['cartype' => 'car1','number' => '123','departure' => 'GHY','arrival' => 'PUI'],
        ['cartype' => 'car2','number' => '567','departure' => 'LHY','arrival' => 'PGY'],
        ['cartype' => 'car2','number' => '567','departure' => 'LHY','arrival' => 'PGY']];
$out = [];  
while (list($k, $v) = each($arr)) {
if(!in_array($v,$out)) {
    array_push($out,$v);
}
}
print_r($out);
// output
Array
(
    [0] => Array
        (
            [cartype] => car1
            [number] => 123
            [departure] => GHY
            [arrival] => PUI
        )

    [1] => Array
        (
            [cartype] => car2
            [number] => 567
            [departure] => LHY
            [arrival] => PGY
        )
)

检查示例

编辑 如果您只想用于检查重复结果

$arr = [['cartype' => 'car1','number' => '123','departure' => 'GHY','arrival' => 'PUI'],
        ['cartype' => 'car2','number' => '567','departure' => 'LHY','arrival' => 'PGY'],
        ['cartype' => 'car2','number' => '567','departure' => 'LHY','arrival' => 'PGY']];
$out = []; 
$checks = [];
while (list($k, $v) = each($arr)) {
if(!in_array([$v['number'],$v['departure'],$v['arrival']],$checks)) {
    array_push($checks,[$v['number'],$v['departure'],$v['arrival']]);
    array_push($out,$v);
}
}
print_r($out);
// output 
Array
(
    [0] => Array
        (
            [cartype] => car1
            [number] => 123
            [departure] => GHY
            [arrival] => PUI
        )

    [1] => Array
        (
            [cartype] => car2
            [number] => 567
            [departure] => LHY
            [arrival] => PGY
        )
)

检查新示例

您必须检查所有数组元素，还是只检查

数字

？您可以使用

序列化（）

将每个数组转换为字符串，使用

数组_unique（）

删除重复项，然后使用

取消序列化（）

将它们转换回数组。

$arr = [['cartype' => 'car1','number' => '123','departure' => 'GHY','arrival' => 'PUI'],
        ['cartype' => 'car2','number' => '567','departure' => 'LHY','arrival' => 'PGY'],
        ['cartype' => 'car2','number' => '567','departure' => 'LHY','arrival' => 'PGY']];
$out = []; 
$checks = [];
while (list($k, $v) = each($arr)) {
if(!in_array([$v['number'],$v['departure'],$v['arrival']],$checks)) {
    array_push($checks,[$v['number'],$v['departure'],$v['arrival']]);
    array_push($out,$v);
}
}
print_r($out);
// output 
Array
(
    [0] => Array
        (
            [cartype] => car1
            [number] => 123
            [departure] => GHY
            [arrival] => PUI
        )

    [1] => Array
        (
            [cartype] => car2
            [number] => 567
            [departure] => LHY
            [arrival] => PGY
        )
)
