I have these arrays in PHP:
我在PHP中有这些数组：
Array1
(
[0] => stdClass Object
(
[expense_id] => 475
[expense_name] => DRAY
[expense_unit_cost] => 270.00
)
[1] => stdClass Object
(
[expense_id] => 476
[expense_name] => FUEL
[expense_unit_cost] => 32.40
)
)
and
和
Array2
(
[0] => stdClass Object
(
[waybill_id] => 20005044
[expense_id] => 475
[tax_select] => tax1
[tax_id] => 1
[tax_name] => GST 5%
[tax_no] =>
[tax_value] => 13.5000
)
[1] => stdClass Object
(
[waybill_id] => 20005044
[expense_id] => 475
[tax_select] => tax2
[tax_id] => 2
[tax_name] => QST 9.975%
[tax_no] =>
[tax_value] => 26.9325
)
[2] => stdClass Object
(
[waybill_id] => 20005044
[expense_id] => 476
[tax_select] => tax1
[tax_id] => 1
[tax_name] => GST 5%
[tax_no] =>
[tax_value] => 1.6200
)
[3] => stdClass Object
(
[waybill_id] => 20005044
[expense_id] => 476
[tax_select] => tax2
[tax_id] => 2
[tax_name] => QST 9.975%
[tax_no] =>
[tax_value] => 3.2319
)
)
I need to combine the 2 arrays using expense_id and the result have to look like this:
我需要使用expense_id组合2个数组，结果必须如下所示：
Array3
(
[0] => stdClass Object
(
[expense_id] => 475
[expense_name] => DRAY
[expense_unit_cost] => 270.00
[expense_taxes] => Array
(
[0] => stdClass Object
(
[waybill_id] => 20005044
[expense_id] => 475
[tax_select] => tax1
[tax_id] => 1
[tax_name] => GST 5%
[tax_no] =>
[tax_value] => 13.5000
)
[1] => stdClass Object
(
[waybill_id] => 20005044
[expense_id] => 475
[tax_select] => tax2
[tax_id] => 2
[tax_name] => QST 9.975%
[tax_no] =>
[tax_value] => 26.9325
)
)
)
[1] => stdClass Object
(
[expense_id] => 476
[expense_name] => FUEL
[expense_unit_cost] => 32.40
[expense_taxes] => Array
(
[0] => stdClass Object
(
[waybill_id] => 20005044
[expense_id] => 476
[tax_select] => tax1
[tax_id] => 1
[tax_name] => GST 5%
[tax_no] =>
[tax_value] => 1.6200
)
[1] => stdClass Object
(
[waybill_id] => 20005044
[expense_id] => 476
[tax_select] => tax2
[tax_id] => 2
[tax_name] => QST 9.975%
[tax_no] =>
[tax_value] => 3.2319
)
)
)
)
As you can see I have on both arrays the expense_id which need to be the key for the final Array3
正如你所看到的，我在两个数组上都有expense_id，它需要是最终Array3的关键
I have tried to loop one array and check for the expense_id key matching but I can't achieve my final array. Also, I have took a look at array_merge, array_map and array_intersect.
我试图循环一个数组并检查expense_id键匹配，但我无法实现我的最终数组。另外，我看了一下array_merge，array_map和array_intersect。
Thank you for your suggestions.
谢谢你的建议。

Try something like...
试试像......
foreach($object AS $key=>$element){ if ($element->expense_id == 475){ $element->expense_taxes[0] = $stdClass; } }
foreach（$ object AS $ key => $ element）{if（$ element-> expense_id == 475）{$ element-> expense_taxes [0] = $ stdClass; }}

It's all a bit more complicate because the actual arrays of objects are got from ajax into PHP, but, I found myself the answer based on KennyDope suggestion.
这有点复杂，因为实际的对象数组是从ajax到PHP的，但是，我发现自己是基于KennyDope建议的答案。
If Array1 is $expenses_obj and Array2 is $invoice_taxes_obj
如果Array1是$ expenses_obj而Array2是$ invoice_taxes_obj
foreach ($expenses_obj as $key => $expense):
foreach ($invoice_taxes_obj as $key => $tax):
if ($expense->expense_id == $invoice_taxes_obj[$key]->expense_id){
$expense->taxes[] = (array)$invoice_taxes_obj[$key];
}
endforeach;
endforeach;
And the final result is what I need:
最后的结果是我需要的：
Array
(
[0] => stdClass Object
(
[expense_id] => 475
[expense_name] => DRAY
[expense_unit_cost] => 270.00
[taxes] => Array

[waybill_id] => 20005044
