WP所有导入功能以处理序列化数组数据

I am using a multi inventory plug-in to store stock levels of products in Woocommerce between 3 locations - they are named 754, 753 and 752

They are stored in database in a serialised array like this:

Key: woocommerce_multi_inventory_inventories_stock

Value: a:3: {i：754; s：0：“ 5”; i：753; s：0：“ 5”; i：752; s：0：“ 5”：“ 5”;}

我试图使用WP所有导入量导入库存级别仅进入这些位置中的1个 - 754，然后离开其他两个。 WP所有导入都可以导入到该序列化数组中，但是当它更改754时，它会覆盖其他两个位置。

任何人是否知道与WP一起使用的php函数是如何在754中仅更改股票水平而不调整其他2的股票水平？

<!DOCTYPE html>
<html>
<body>

<?php
 $array["a"] = "Foo";
    $array["b"] = "Bar";
    $array["c"] = "Baz";
    $array["d"] = "Wom";

    $str = serialize($array);
    print $str . "\n";
 
?>

</body>
</html>

使用上述方法，您可以使用WP All Import Optoct中的“可用键”为自定义字段创建序列化数据。

序列化数组的说明如下：

Array ( [1] => elem 1 [2] => elem 2 [3] => elem 3 ) 

a:3:{i:1;s:6:"elem 1";i:2;s:6:"elem 2";i:3;s:7:" elem 3";}

如果您仍然对“二级输出”感到好奇，它相当简单：a = array，3 = {}}中三个元素的大小。在其中，您的i =整数/索引等于1，len 6等于“ elem 1”，整数等于2 ..等等。当您这样阅读时，它相当清楚。您可以想象在内部容易包含多个级别的数组/对象，但是修改非常不明智，您应该真正不进行修改，然后序列化以确保一致性。

<!DOCTYPE html>
<html>
<body>

<?php
 $array["a"] = "Foo";
    $array["b"] = "Bar";
    $array["c"] = "Baz";
    $array["d"] = "Wom";

    $str = serialize($array);
    print $str . "\n";
 
?>

</body>
</html>

Using the above method you can create serialize data for the custom field using the key available in wp all import options.

Explanation of serialize array is as follows:

Array ( [1] => elem 1 [2] => elem 2 [3] => elem 3 ) 

a:3:{i:1;s:6:"elem 1";i:2;s:6:"elem 2";i:3;s:7:" elem 3";}

In case you were still curious about the "secondary output", its fairly simple: a = array, 3 = of size three elements within the {}'s. inside that, you have i=integer/index equalling 1, string of len 6 equalling "elem 1", integer equalling 2.. etc etc.. Its fairly clear when you read it like that. You can imagine multiple levels of arrays/objects being easily contained within, however modification is very unwise, you should really unserialize modify then serialize to ensure consistency.
