[英]How to create multi-dimensional associative array
I have this example table data, it actually has ids, prices, more stuff, but i think i can ask with this data, im using PHP as my language: 我有这个示例表数据,它实际上具有ID,价格,更多内容,但是我想我可以使用此数据进行查询,即时通讯使用PHP作为我的语言:
id category product complement_type option
1 Pizza Large Pizza Bread Brown bread
2 Pizza Small Pizza Bread White bread
3 Pizza Small Pizza Ingredients Olives
4 Salads Green Salad Extras Bacon
5 Salads Cesars Salad Extras Lettuce
i already have the query for this table, 我已经有查询此表,
now i want to convert ir to an array of this type 现在我想将ir转换为这种类型的数组
array(
[Pizza] => array(
[Large Pizza] => array(
[Bread] => Brown Bread
)
),
array(
[Small Pizza] => array(
[Bread] => White Bread
[Ingredients] => Olives
),
)
),
[Salads] => array(
[Green Salad] => array(
[Extras] => Bacon
)
[Cesar Salad] => array(
[Extras] => Lettuce
)
)
that array is what i am trying to achieve, but i just cant get it right 该数组是我想要实现的,但是我无法正确完成
i know i have to loop it with a for loop, maybe add a while loop to get the changes in the categories, but i just dont seem to find the way to do it, any ideas on how to achieve this? 我知道我必须使用for循环来循环它,也许添加一个while循环来获取类别中的更改,但是我只是似乎没有找到实现它的方法,关于如何实现这一点的任何想法?
i appreciate any idea 我很欣赏任何想法
Again, im using PHP 再次,即时通讯使用PHP
thanks 谢谢
Edit: heres the link to the data im getting, its a little different, but its the same principle 编辑:这是指向数据即时获取的链接,虽然有点不同,但原理相同

First of all: your original array — as posted is comment — if an array of objects: this preliminar note is to understand the syntax ->
, otherwise obscure simply reading your main question. 首先:您的原始数组(已发布,是注释),如果是对象数组:此初步注意事项是理解语法
->
,否则仅阅读您的主要问题就难以理解。
Assuming your table results are stored in array $array
, you can try in this way: 假设您的表结果存储在数组
$array
,则可以按以下方式尝试:
$result = array();
foreach( $array as $row )
{
if( !isset( $result[ $row->category ] ) )
{
$result[ $row->category ] = array();
}
if( !isset( $result[ $row->category ][ $row->product ] ) )
{
$result[ $row->category ][ $row->product ] = array();
}
$result[ $row->category ][ $row->product ][ $row->complement_type ] = $row->option;
}
At beginning, I init an empty array. 首先,我初始化一个空数组。 Then — through a
foreach
loop, I process each element of $array
and — if primary key (the product) doesn't exist in the result array, I create it as empty array; 然后-通过一个
foreach
循环,我处理$array
每个元素,并且-如果结果数组中不存在主键(产品),则将其创建为空数组; then I perform same action for category subkey (Large Pizza, etc). 然后我对类别子项(大披萨等)执行相同的操作。 At last, I add the complement type.
最后,我添加补码类型。
