php数组将一个数组中的值添加到另一个数组中
php数组将一个数组中的值添加到另一个数组中
提问于 2017-12-26 20:02:08
我有两个数组，这两个数组都是从不同的mysql查询生成的，如下所示：
数组1
[0] => Array
(
[value] => black
[hex_colour] => #000000
)
[1] => Array
(
[value] => blue
[hex_colour] => #4e5f98
)
[2] => Array
(
[value] => brown
[hex_colour] => #a3775e
)数组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添加到数组1中，这样结果将是：
新数组
[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
)我很抱歉，我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词来搜索google，但都没有成功。任何帮助都会得到极大的欢迎。

我认为这满足了你的要求。
$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，您得到的数组与队列中提到的数组相同。如果您有任何疑问，请在下面发表评论。

$count_array=[];
foreach($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']]
];
