我在数组中有一些问题。我有3个数组。我想创建一个名为history的行，然后根据shipment_id插入该行。如果相同的shipment_id，它将分组相同的发货id。
Array a (
[0] => Array (
[order_id] => 231
[name] => "One Layer Lunch Box
[quantity] => 1
[username] => linkath
[shipment_id] => SI000116 )
[1] => Array (
[order_id] => 231
[name] => "Test 03
[quantity] => 1
[username] => happymart
[shipment_id] => SI000117 ) )
Array b (
[0] => Array (
[shipment_id] => SI000116
[date] => 2016-11-09 09:40:26
[status] => Ready to ship
[description] => Your item(s) is being packed and ready for shipment at our vendor's warehouse. )
[1] => Array (
[shipment_id] => SI000116
[date] => 2016-11-09 10:16:04
[status] => Shipped
[description] => Your item(s) is being shipped with . For more details on your shipment, please go to Tracking, enter your tracking number ) )
Array c (
[0] => Array (
[shipment_id] => SI000117
[date] => 2016-11-09 15:27:45
[status] => Ready to ship
[description] => Your item(s) is being packed and ready for shipment at our vendor's warehouse. ) )
符合预期数组
Array a (
[0] => Array (
[order_id] => 231
[name] => "One Layer Lunch Box
[quantity] => 1
[username] => linkath
[shipment_id] => SI000116
[history] => Array b (
[0] => Array (
[shipment_id] => SI000116
[date] => 2016-11-09 09:40:26
[status] => Ready to ship
[description] => Your item(s) is being packed and ready for shipment at our vendor's warehouse. )
[1] => Array (
[shipment_id] => SI000116
[date] => 2016-11-09 10:16:04
[status] => Shipped
[description] => Your item(s) is being shipped with . For more details on your shipment, please go to Tracking, enter your tracking number ) ) )
[1] => Array (
[order_id] => 231
[name] => "Test 03
[quantity] => 1
[username] => happymart
[shipment_id] => SI000117
[history] => Array c (
[0] => Array (
[shipment_id] => SI000117
[date] => 2016-11-09 15:27:45
[status] => Ready to ship
[description] => Your item(s) is being packed and ready for shipment at our vendor's warehouse. ) )
)
)
我试过的这段代码。
//tracker
$getshipment = $this->model_account_order->getshipmentByOrder($this->request->get['order_id']);
foreach ($getshipment as $shipment) {
$data['shipment'][] = array(
'shipment_id' => $shipment['shipment_id']
);
}
$i=0;
foreach ($data['shipment'] as $key) {
$gethistorybysid[$i] = $this->model_account_order->getHistory($data['shipment'][$i]['shipment_id']);
$i++;
}
$u=0;
foreach ($getshipment as $final) {
$data['final'][] = array(
'name' => $shipment['name'],
'quantity' => $shipment['quantity'],
'shipment_id' => $shipment['shipment_id'],
'history' => array($gethistorybysid[$u])
);
$u++;
}
print_r($data['final']);
这个代码我不知道如何比较相同的货物id。有办法吗?
您可以使用简单的foreach()和array_column来获得您想要的结果。你可以试试下面的方法，一定有效。
//Loop the main Array A as follows
foreach ($arrayA as $val) {
//Take the array B and C in a loop and check for shipment Id
foreach (array($arrayB, $arrayC) as $history) {
// Push the array in history key(of Array A) if the match is found.
if (in_array($val['shipment_id'], array_column($history, 'shipment_id')) {
foreach ($history as $value) {
$val['history'][] = $value;
}
}
}
}
这只是一个想法，我认为这应该可以工作，如果不行，你可以根据你的需要修改
对于期望的输出:
# `array` is your first array where you want the shipments to be merged in.
# `array_b` is the array containing the history.
foreach($array as $contents){
if(isset($contents['shipment_id'])){
unset($match);
foreach($array_b as $key => $value){
if(isset($value['shipment_id'])){
if($value['shipment_id'] == $contents['shipment_id']){
$match[] = $value['shipment_id'];
}
}
}
if(!empty($match)){
$contents['shipment_id'] = $match;
}
}
}
当没有找到历史记录时，此方法也将保留shipment_id的值。
但是，像jitendrapurohit的答案那样创建一个单独的列是更好的解决方案。
