Question

我想要联盟2阵列$A和$B示例：

$A = Array(
    0=>array(
            'lable' =>"label0",
            'id_poste'=>1,
            'id_part'=>11
    ),
    1=>array(
            'lable' =>"label1",
            'id_poste'=>2,
            'id_part'=>12
            ),
    2=>array(
            'lable' =>"label2",
            'id_poste'=>3,
            'id_part'=>13
    ),
    3=>array(
            'lable' =>"label3",
            'id_poste'=>4,
            'id_part'=>14
            )
);

$B = Array(
    0=>array(
            'lable' =>"label0",
            'id_poste'=>1,
            'id_part'=>11
    ),
    1=>array(
            'lable' =>"label1_X",
            'id_poste'=>2,
            'id_part'=>12
            ),
    2=>array(
            'lable' =>"label2",
            'id_poste'=>3,
            'id_part'=>13
    ),
    3=>array(
            'lable' =>"label3_X",
            'id_poste'=>4,
            'id_part'=>14
            )
);

这两个数组之间的并集结果将是

/*
$result => Array(
    0=>array(
            'lable' =>"label0",
            'id_poste'=>1,
            'id_part'=>11
    ),
    1=>array(
            'lable' =>"label1",
            'id_poste'=>2,
            'id_part'=>12
            ),
    2=>array(
            'lable' =>"label1_X",
            'id_poste'=>2,
            'id_part'=>12
            )       
    3=>array(
            'lable' =>"label2",
            'id_poste'=>3,
            'id_part'=>13
    ),
    4=>array(
            'lable' =>"label3",
            'id_poste'=>4,
            'id_part'=>14
            ),
    5=>array(
            'lable' =>"label3_X",
            'id_poste'=>4,
            'id_part'=>14
            )
);
*/

我尝试过：

$C = $A+$B;
echo '<pre>';
print_r($C);
echo '</pre>'

但结果不是我的预期？有人可以帮忙吗？

由于

EIDT：

如果使用array_merge($A, $B);

Array
(
[0] => Array
    (
        [lable] => label0
        [id_poste] => 1
        [id_part] => 11
    )

[1] => Array
    (
        [lable] => label1
        [id_poste] => 2
        [id_part] => 12
    )

[2] => Array
    (
        [lable] => label2
        [id_poste] => 3
        [id_part] => 13
    )

[3] => Array
    (
        [lable] => label3
        [id_poste] => 4
        [id_part] => 14
    )

[4] => Array
    (
        [lable] => label0
        [id_poste] => 1
        [id_part] => 11
    )

[5] => Array
    (
        [lable] => label1_X
        [id_poste] => 2
        [id_part] => 12
    )

[6] => Array
    (
        [lable] => label2
        [id_poste] => 3
        [id_part] => 13
    )

[7] => Array
    (
        [lable] => label3_X
        [id_poste] => 4
        [id_part] => 14
    )

）

就像我们在这里看到的那样，数组是重复的：所以我们使用array_unique但是我们仍然遇到错误或警告。

Answer 1

我得到的解决方案有点棘手。我将合并A及其与B的区别。为了确定这种差异，我使用array_udiff：我认为它很棘手，因为它依赖于标签密钥的识别。

$C = array_merge($A, 
            array_udiff($B, $A, 
                        function($a,$b){
                            return strcmp($a['lable'],$b['lable']);
                        }
           )
);

Answer 2

array_merge($A, $B);

是您正在寻找的

Answer 3

为此目的使用array_merge()

$C = array_merge($A,$B);
echo '<pre>';
print_r($C);
echo '</pre>'

参见工作示例http://codepad.viper-7.com/LrVHn3

Answer 4

您可以使用array_merge()。因为您需要删除重复项，所以您还必须使用array_unique() ....

$C = array_unique(array_merge($A,$B), SORT_REGULAR);
echo '<pre>';
print_r($C);
echo '</pre>'

请参阅array_unique和array_merge

它给了我正确的结果

Array
(
    [0] => Array
        (
            [lable] => label0
            [id_poste] => 1
            [id_part] => 11
        )

    [1] => Array
        (
            [lable] => label1
            [id_poste] => 2
            [id_part] => 12
        )

    [2] => Array
        (
            [lable] => label2
            [id_poste] => 3
            [id_part] => 13
        )

    [3] => Array
        (
            [lable] => label3
            [id_poste] => 4
            [id_part] => 14
        )

    [5] => Array
        (
            [lable] => label1_X
            [id_poste] => 2
            [id_part] => 12
        )

    [7] => Array
        (
            [lable] => label3_X
            [id_poste] => 4
            [id_part] => 14
        )

)

Answer 5

<?php

$input = array_merge( $A, $B );
$input = array_map( "unserialize", array_unique(array_map("serialize", $input)) );

var_dump( $input );

联盟两个关联数组PHP？
