Question

我需要将第一个数组中的值放在顶部，然后将它们插入到底部数组中，并在合并时将key指定为url。我怎么能这样做？

我尝试了array_merge_recursive()，但似乎没有这样做。

之前

$batchedDomains = Array
(
    [0] => http://www.domain.com/1/
    [1] => http://www.domain.com/2/
)

$json_a = Array
(
    [0] => stdClass Object
        (
            [pda] => 91.1624138732
            [upa] => 1
        )

    [1] => stdClass Object
        (
            [pda] => 91.1624138732
            [upa] => 1
        )

)

后

Array
(
    [0] => stdClass Object
        (
            [pda] => 91.1624138732
            [upa] => 1
            [url] => http://www.domain.com/1/
        )

    [1] => stdClass Object
        (
            [pda] => 91.1624138732
            [upa] => 1
            [url] => http://www.domain.com/2/
        )

)

这应该适合你：

只需使用array_map()遍历两个数组，然后将属性url添加到stdClass object $v1，其值为$v2。

<?php

    $json_a = array_map(function($v1, $v2) {
        $v1->url = $v2;
        return $v1;
    }, $json_a, $batchedDomains);

    print_r($json_a);

?>

输出：

Array
(
    [0] => stdClass Object
        (
            [pda] => 91.1624138732
            [upa] => 1
            [url] => http://www.domain.com/1/
        )

    [1] => stdClass Object
        (
            [pda] => 91.1624138732
            [upa] => 1
            [url] => http://www.domain.com/2/
        )
