Question

我有两个阵列。

$a=array('caption'=>array('c one','c two'));
$b=array('photos'=>array('photo one','photo two'));

我想合并到

Array (
    [0] => Array (
        [caption] => c one
        [file] => photo one
    )
    [1] => Array (
        [caption] => c two
        [file] => photo two
    )
)

或合并到

Array (
    [0] => Array (
        [0] => c one
        [1] => photo one
    )
    [1] => Array (
        [0] => c two
        [1] => photo two
    )
)

你是怎么做到的？

Answer 1

您可以使用嵌套循环，只需跟踪您的密钥。

foreach ([$a, $b] as $array) {
    foreach ($array as $text_key => $values) {
        foreach ($values as $numeric_key => $value) {
            $result[$numeric_key][$text_key] = $value;
        }
    }
}

Answer 2

最后一种情况可以通过array_map函数

完成

$res = array_map(null, $a['caption'], $b['photos']);

Answer 3

如果数组没有比键值更多的共同点，那么这应该有效。

它循环一个数组并使用该键从另一个数组中获取值。

1.1.1

输出：

$a=array('caption'=>array('c one','c two'));
$b=array('photos'=>array('photo one','photo two'));


Foreach($a['caption'] as $key => $capt){
    $new[$key]['caption'] = $capt;
    $new[$key]['photos'] = $b['photos'][$key];
}

Var_dump($new);
