我有 2 个数组，如下所示:
I have 2 array like follows:
$array1 = [
'0' => [
'no_invoice' => 'INV0001',
'product_code' => '1111111',
],
'1' => [
'no_invoice' => 'INV0001',
'product_code' => '1111112',
]
];
$array2 = [
'0' => [
'product_code' => '1111112',
'free_valie' => 839,
'count' => 1240
],
];
是否可以将上面的数组组合成这样:
Is it possible to combine arrays above to be like this:
Array(
[0] => Array
(
'no_invoice' => 'INV0001',
'product_code' => '1111111',
)
[1] => Array
(
'no_invoice' => 'INV0001',
'product_code' => '1111112',
'free_valie' => 839,
'count' => 1240
)
)
所以，如果数组具有相同的产品代码，那么它将像上面的例子一样加入.
So, if array have same product code, then it will join like the example above.
我尝试过使用数组合并，array_merge($array1, $array2);但是结果是这样的:
I have been tried with use array merge, array_merge($array1, $array2);
But the result is like this:
Array(
[0] => Array
(
'no_invoice' => 'INV0001',
'product_code' => '1111111',
)
[1] => Array
(
'no_invoice' => 'INV0001',
'product_code' => '1111112',
)
[2] => Array
(
'product_code' => '1111112',
'free_valie' => 839,
'count' => 1240
)
)
此代码将满足您的需求.它使用 <遍历 $array1 中的每个值code>array_search 以查看条目的 product_code 是否也存在于 $array2 中(通过查看 product_code使用 array_column<提取的 $array2 列/代码>).如果是，则合并这些值.请注意，我们在 foreach 中使用了 &$val，导致值通过引用传递，从而允许在循环中修改它
This code will do what you want. It loops over each value in $array1, using array_search to see if the entrie's product_code is also present in $array2 (by looking through the product_code column of $array2 extracted using array_column). If it is, the values are merged. Note that we use &$val in the foreach, causing the value to be passed by reference which allows it to be modified in the loop
foreach ($array1 as &$val) {
if (($k = array_search($val['product_code'], array_column($array2, 'product_code'))) !== false) {
$val = array_merge($val, $array2[$k]);
}
}
print_r($array1);
输出:
Array
(
[0] => Array
(
[no_invoice] => INV0001
[product_code] => 1111111
)
[1] => Array
(
[no_invoice] => INV0001
[product_code] => 1111112
[free_valie] => 839
[count] => 1240
)
)
