Question

我有2个数组，都是从单独的mysql查询生成的，如下所示：

ARRAY 1

[0] => Array
    (
        [value] => black
        [hex_colour] => #000000
    )

[1] => Array
    (
        [value] => blue
        [hex_colour] => #4e5f98
    )

[2] => Array
    (
        [value] => brown
        [hex_colour] => #a3775e
    )

ARRAY 2

[0] => Array
    (
        [value] => black
        [count] => 122
    )

[1] => Array
    (
        [value] => blue
        [count] => 33
    )

[2] => Array
    (
        [value] => brown
        [count] => 5
    )

我的问题是如何将[count]添加到ARRAY 1，结果将是：

新ARRAY

[0] => Array
    (
        [value] => black
        [hex_colour] => #000000
        [count] => 122
    )

[1] => Array
    (
        [value] => blue
        [hex_colour] => #4e5f98
        [count] => 33
    )

[2] => Array
    (
        [value] => brown
        [hex_colour] => #a3775e
        [count] => 5

    )

我道歉我还没有得到我尝试过的代码示例，但我使用了许多不同的搜索字词搜索了谷歌，但没有运气。任何帮助都会得到很大的帮助。

Answer 2

$count_array=[];

foreach($array2 as $count)
{
    $count_array[$count['value']]=$count['count'];
}
$final=[];
foreach($array1 as $value)
{
    $final=[
             "value"=>$value['value'],
             "hex_colour"=>$value['hex_colour'],
             "count"=>$count_array[$value['value']]
        ];
}

Answer 3

您可以尝试以下代码 -

  $array1= array(
    'value' => 'black',
   'hex_colour' => '#000000'
);
$array2= array(
    'value' => 'black',
   'count' => '122'
);

$result = array_merge($array1, $array2);

print_r($result);

Answer 4

我认为这是满足你的要求。

$arrayName1[0] = array(
        'value' => "black",
        'hex_colour' => "#000000",
    );
    $arrayName1[1] = array(
        'value' => "blue",
        'hex_colour' => "#4e5f98",
    );
    $arrayName1[2] = array(
        'value' => "brown",
        'hex_colour' => "#a3775e",
    );

    $arrayName2[0] = array(
        'value' => "black",
        'count' => "122",
    );
    $arrayName2[1] = array(
        'value' => "blue",
        'count' => "33",
    );
    $arrayName2[2] = array(
        'value' => "brown",
        'count' => "5",
    );

    foreach ($arrayName1 as $key => $row1) {
        foreach ($arrayName2 as $key => $row2) {
            if($row1['value'] == $row2['value'] ){
                $row1['count'] = $row2['count'];
                $data[] = $row1;
                break;
            }
        }
    }

在$data中，您的队列中提到了相同的数组。如果您有任何疑问，请在下面评论。
