php按值将数组拆分为2个数组

我使用array_intersect在唯一pos的循环中查找pos。
然后我使用array_inyersect_key来获取数量。
这只需要每个唯一的采购订单id重复一次。
这意味着它比循环整个数组有更好的性能。

编辑:添加了extract来创建这两个变量。但如果我是你的话,我宁愿把他们留在队里。

$pods = array_unique($arr["purchase_order_details_id"]);

Foreach($pods as $pod){
    $PO = array_intersect($arr["purchase_order_details_id"], [$pod]);
    $qt = array_intersect_key($arr["quantity_received"], $PO);
    $new[$pod] = ["purchase_order_details_id" => $PO, "quantity_received" => $qt];
}
Var_dump($new);
extract($new);

尝试使用以下代码:

$array = array();   
foreach($arr['purchase_order_details_id'] as $key => $val)
{
    $array[$val]['purchase_order_details_id'][] = $val;
    $array[$val]['quantity_received'][] = $arr['quantity_received'][$key];
}

echo "<pre>";
    print_r($array);
echo "</pre>";

extract($array);

echo "<pre>";
    print_r($POD1);
echo "</pre>";

echo "<pre>";
    print_r($POD2);
echo "</pre>";

foreach ($arr as $key => $val) {
    $size = ceil(count($val) / 2);

    $arr2 = array_chunk($val, $size, true);

    $pod_2[$key] = $arr2[0];
    $pod_1[$key] = $arr2[1];
}

var_dump($pod_2);
var_dump($pod_1);
