对象的JavaScript数组分解为PHP数组

Question

经过数小时的毕加索编码（用我的术语 ），我陷入了如何有效地将对象的JavaScript数组转换为PHP（通过AJAX发送）的困境。

在JavaScript中，JSON编码后的对象数组如下所示：

[
    {"pid":"282","seller_id":"3","qty":"5"},
    {"pid":"284","sn":"1234","seller_id":2,"qty":"1"},
    {"pid":"284","sn":"2345","seller_id":2,"qty":"1"},
    {"pid":"284","sn":"3456","seller_id":2,"qty":"1"},
    {"pid":"111","sn":"987","seller_id":2,"qty":"1"}
]

有两个数据分组-请注意，第一个传输缺少序列号，并且是向外部供应商出售的。 接下来的4个都属于“我自己”（用户是Seller_id：2），因此这些是产品的内部转让。

无论如何，这两种类型必须以不同的方式处理，因此，如果将它们放在单独的数组中会很有帮助。

因此，我希望以两个PHP数组结束：

arrSale[0] = "pid":"282","seller_id":"3","qty":"5"

和

arrXfer[0] = "pid":"284","sn":"1234","seller_id":2,"qty":"1"
arrXfer[1] = "pid":"284","sn":"2345","seller_id":2,"qty":"1"
arrXfer[2] = "pid":"284","sn":"3456","seller_id":2,"qty":"1"
arrXfer[3] = "pid":"111","sn":"987","seller_id":2,"qty":"1"

我知道我必须使用$arrPHP = json_decode(jsonItems); 解码JSON，但是对象发生了什么？ 我如何将它们分为两组？ 我什至找不到讨​​论此问题的网站资源。

尝试这个

$JSON = '[
    {"pid":"282","seller_id":"3","qty":"5"},
    {"pid":"284","sn":"1234","seller_id":2,"qty":"1"},
    {"pid":"284","sn":"2345","seller_id":2,"qty":"1"},
    {"pid":"284","sn":"3456","seller_id":2,"qty":"1"},
    {"pid":"111","sn":"987","seller_id":2,"qty":"1"}
]';

$array = json_decode($JSON);

$arrSale = $arrXfer = array();

foreach($array as $obj)
    if(isset($obj->sn)) $arrXfer[] = (array)$obj;
        else $arrSale[] = (array)$obj;

print_r($arrSale);
print_r($arrXfer);

它给我们：

Array(
    [0] => Array([pid] => 282[seller_id] => 3[qty] => 5)
)

Array(
    [0] => Array([pid] => 284[sn] => 1234[seller_id] => 2[qty] => 1)
    [1] => Array([pid] => 284[sn] => 2345[seller_id] => 2[qty] => 1)  
    [2] => Array([pid] => 284[sn] => 3456[seller_id] => 2[qty] => 1)  
    [3] => Array([pid] => 111[sn] => 987[seller_id] => 2[qty] => 1)  
)
