JavaScript 对象数组分解为 PHP 数组

Question

经过几个小时的毕加索编码(我的术语)后，我陷入了如何有效地将这个 JavaScript 对象数组转换为 PHP(通过 AJAX 发送)的问题。

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，第一次传输缺少序列号，并且传输给外部 vendor ，因此是一次销售。接下来的4个都是“我自己”(用户是seller_id:2)，所以这些是产品的内部转移。

无论如何，这两种类型必须以不同的方式处理，因此如果它们位于单独的数组中将会非常有帮助。

因此，我希望最终得到两个 PHP 数组:

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); 来解码 JSON，但是对象会发生什么情况？我如何将他们分成两组？我什至找不到讨​​论此问题的网站资源。

试试这个

$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);

它给了我们:

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)  
)
