PHP,将带括号的字符串转换为数组

我正在查询API并发送一个JSON响应,然后我将其解码为一个数组.这部分工作正常,但API以相当不友好的格式发送信息.

我将粘贴我遇到问题的部分.本质上,我试图将每个像键一样更改为自己的数组.

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
)

现在我想做的是做
它是这样的：

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
    )
)

这有什么实际的方法吗？

谢谢！

解决方法:

参考文献是你的朋友：

$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;
}

然而,还有另一种更简单的方法,尽管它在功能复杂性方面效率稍低：

parse_str(http_build_query($inputArray), $result);
