Question

基本上我需要搜索一个数组并替换其数据

主要思想是从旧数组中查找数据并验证它们是否存在于新数组中（如果没有添加的话）

这是我的旧数组

$array1 = array(
array('id' => '1','data1' => 'ect bla bla'),
array('id' => '2','data2' => 'ect bla bla'),
array('id' => '3','data3' => 'ect bla bla'),
array('id' => '6','data3' => 'new data'),
array('id' => '100','data3' => 'this data is added if it does not exist in the array')
);

这是我的新数组

$array2 = array(
array('id' => '1','data1' => 'new data'),  //example data that are modified
array('id' => '2','data2' => 'new data'),  //example data that are modified
array('id' => '3','data3' => 'new data'),  //example data that are modified

array('id' => '4','data3' => 'new data'),
array('id' => '5','data3' => 'new data'),

array('id' => '6','data3' => 'new data')   //example data that are modified
);

这部分我不知道要放什么

foreach ($array1 as $value) {
     //this is the id.. I imagine that here is where all the magic goes xd
     $value['id']
}

我需要这个结果

print_r($array2);


Array
(
    [0] => Array
        (
            [id] => 1
            [data1] => ect bla bla
        )

    [1] => Array
        (
            [id] => 2
            [data2] => ect bla bla
        )

    [2] => Array
        (
            [id] => 3
            [data3] => ect bla bla
        )

    [3] => Array
        (
            [id] => 4
            [data3] => new data
        )

    [4] => Array
        (
            [id] => 5
            [data3] => new data
        )

    [5] => Array
        (
            [id] => 6
            [data3] => ect bla bla
        )
   [6] => Array
    (
        [id] => 7
        [data3] => this data is added if it does not exist in the array
    )

)

尝试array_replace_recursive($array2, $array1);

http://us3.php.net/manual/en/function.array-replace-recursive.php

这将提供以下输出：

Array
(
[0] => Array
    (
        [id] => 1
        [data1] => ect bla bla
    )

[1] => Array
    (
        [id] => 2
        [data2] => ect bla bla
    )

[2] => Array
    (
        [id] => 3
        [data3] => ect bla bla
    )

[3] => Array
    (
        [id] => 6
        [data3] => new data
    )

[4] => Array
    (
        [id] => 100
        [data3] => this data is added if it does not exist in the array
    )

[5] => Array
    (
        [id] => 6
        [data3] => new data
    )

)

然后使其独特使用

array_map("unserialize", array_unique(array_map("serialize", $array3)));

PHP查找键值数组并替换
