我有一个包含常见 activity_code
的数组。我需要在项目字段中添加 pri
记录
Array ( [0] => Array ( [pr] => Array ( [id] => 1 [activity_code] => 20220101PR0001 [serial_number] => 0001/2022 ) [pri] => Array ( [item] => Item 1 [description] => Description 1 [quantity] => 15 [unit] => Each [unit_price] => 65000.00 ) ) [1] => Array ( [pr] => Array ( [id] => 1 [activity_code] => 20220101PR0001 [serial_number] => 0001/2022 ) [pri] => Array ( [item] => Item 2 [description] => Description 2 [quantity] => 15 [unit] => Each [unit_price] => 2500.00 ) ) )
items
字段中应该有 2 个数组,但是我只插入了 1 个数组。
这是代码,我已经尝试过。
foreach ($records as $key => $record) { $purchaseRequisition = $record['pr']; $items = $record['pri']; if (!array_key_exists($purchaseRequisition['activity_code'], $purchaseArray)) { $purchaseArray[$purchaseRequisition['activity_code']] = []; } $purchaseArray[$purchaseRequisition['activity_code']] = [ 'serialNumber' => $record['pr']['serial_number'], 'items' => [] ]; $purchaseArray[$purchaseRequisition['activity_code']]['items'][$key] = $items; }
这是我需要的数组结构
谁能告诉我我在这里犯了什么错误?

您正在覆盖 $purchaseArray[$purchaseRequisition['activity_code']]
,而不是向其中推送新元素。要推入数组,请分配给 $array[]
。
foreach ($records as $key => $record) { $purchaseRequisition = $record['pr']; $items = $record['pri']; if (!array_key_exists($purchaseRequisition['activity_code'], $purchaseArray)) { $purchaseArray[$purchaseRequisition['activity_code']] = []; } $purchaseArray[$purchaseRequisition['activity_code']][] = [ 'serialNumber' => $record['pr']['serial_number'], 'items' => [] ]; $purchaseArray[$purchaseRequisition['activity_code']]['items'][$key] = $items; }

使用下面的代码:
foreach ($records as $key => $record) { $purchaseRequisition = $record['pr']; $items[] = $record['pri']; if (!array_key_exists($purchaseRequisition['activity_code'], $purchaseArray)) { $purchaseArray[$purchaseRequisition['activity_code']] = []; } $purchaseArray[$purchaseRequisition['activity_code']] = [ 'serialNumber' => $record['pr']['serial_number'], 'items' => [] ]; $purchaseArray[$purchaseRequisition['activity_code']]['items'] = $items; }
