[英]PHP, Convert a string with brackets into an array
I am querying an API and it sends a JSON response which I am then decoding into an array. 我正在查询一个API,它发送一个JSON响应,然后将其解码为数组。 This part works fine, but the API sends the information in a rather unfriendly format. 这部分工作正常,但是API以相当不友好的格式发送信息。
I will paste the part I am having issues with. 我将粘贴遇到问题的部分。 Essentially I am trying to change each like keys into their own array. 本质上,我试图将每个类似的键更改为它们自己的数组。
Array
(
[name] => Name
[address] => 123 Street Rd
[products[0][product_id]] => 1
[products[0][price]] => 12.00
[products[0][name]] => Product Name
[products[0][product_qty]] => 1
[products[1][product_id]] => 2
[products[1][price]] => 3.00
[products[1][name]] => Product Name
[products[1][product_qty]] => 1
[systemNotes[0]] => Note 1
[systemNotes[1]] => Note 2
)
Now what I would like to do is to make it like this: 现在我想做的就是这样:
Array
(
[name] => Name
[address] => 123 Street Rd
[product] => Array
(
[0] => Array
(
[product_id] => 1
[price] => 12.00
[name] => Product Name
[product_qty] => 1
)
[1] => Array
(
[product_id] => 2
[price] => 3.00
[name] => Product Name
[product_qty] => 1
)
[systemNotes] => Array
(
[0] => Note 1
[1] => Note 2
)
)
Is there any practical way of doing this? 有实际的方法吗?
Thanks! 谢谢!
References are your friend here: 参考是您的朋友在这里:
$result = array();
foreach ($inputArray as $key => $val) {
$keyParts = preg_split('/[\[\]]+/', $key, -1, PREG_SPLIT_NO_EMPTY);
$ref = &$result;
while ($keyParts) {
$part = array_shift($keyParts);
if (!isset($ref[$part])) {
$ref[$part] = array();
}
$ref = &$ref[$part];
}
$ref = $val;
}
However, there is another, much simpler way, although it is a little less efficient in terms of functional complexity: 但是,还有另一种更简单的方法,尽管在功能复杂性方面效率较低:
parse_str(http_build_query($inputArray), $result);
With $array
your source array : 使用$array
您的源数组:
$new_array = array("name" => $array["name"], "address" => $array["address"]);
foreach($array["products"] AS $product)
{
$new_array["product"][] = array(
"product_id" => $product["produit_id"],
"price" => $product["price"],
"name" => $product["name"],
"product_qty" => $product["product_qty"]);
}
foreach($array["systemNotes"] AS $note)
{
$new_array["systemNotes"][] = $note;
}
It is just browsing and creating a new structure. 它只是浏览并创建一个新结构。 ^^ ^^
Edit : Something generic could be done recursively. 编辑:通用的东西可以递归地完成。 Calling the same function as long as the browsed element is_array
, and building a new array according to the keys and values. 只要已浏览的元素is_array
调用相同的函数,然后根据键和值构建一个新的数组。 Looks like a file system ^^ 看起来像文件系统^^
