Convert multidimensional objects to array
提问by Giri
I'm using amazon product advertising api. Values are returned as a multidimensional objects.
我正在使用亚马逊产品广告 api。值作为多维对象返回。
It looks like this:
它看起来像这样：
object(AmazonProduct_Result)#222 (5) {
["_code":protected]=>
int(200)
["_data":protected]=>
string(16538)
array(2) {
["IsValid"]=>
string(4) "True"
["Items"]=>
array(1) {
[0]=>
object(AmazonProduct_Item)#19 (1) {
["_values":protected]=>
array(11) {
["ASIN"]=>
string(10) "B005HNF01O"
["ParentASIN"]=>
string(10) "B008RKEIZ8"
["DetailPageURL"]=>
string(120) "http://www.amazon.com/Case-Logic-TBC-302-FFP-Compact/dp/B005HNF01O?SubscriptionId=AKIAJNFRQCIJLTY6LDTA&tag=*********-20"
["ItemLinks"]=>
array(7) {
[0]=>
object(AmazonProduct_ItemLink)#18 (1) {
["_values":protected]=>
array(2) {
["Description"]=>
string(17) "Technical Details"
["URL"]=>
string(217) "http://www.amazon.com/Case-Logic-TBC-302-FFP-Compact/dp/tech-data/B005HNF01O%3FSubscriptionId%3DAKIAJNFRQCIJLTY6LDTA%26tag%*******-20%26linkCode%3Dxm2%26camp%3D2025%26creative%3D386001%26creativeASIN%3DB005HNF01O"
}
}
[1]=>
object(AmazonProduct_ItemLink)#17 (1) {
["_values":protected]=>
array(2) {
I mean it also has array inside objects. I would like to convert all of them into a multidimensional array.
我的意思是它在对象内部也有数组。我想将它们全部转换为多维数组。

I know this is old but you could try the following piece of code:
我知道这很旧，但您可以尝试以下代码：
$array = json_decode(json_encode($object), true);
$array = json_decode(json_encode($object), true);
where $object is the response of the API.
其中 $object 是 API 的响应。

You can use recursive function like below:
您可以使用如下递归函数：
function objToArray($obj, &$arr){
if(!is_object($obj) && !is_array($obj)){
$arr = $obj;
return $arr;
}
foreach ($obj as $key => $value)
{
if (!empty($value))
{
$arr[$key] = array();
objToArray($value, $arr[$key]);
}
else
{
$arr[$key] = $value;
}
}
return $arr;
}

function convertObjectToArray($data) {
if (is_object($data)) {
$data = get_object_vars($data);
}
if (is_array($data)) {
return array_map(__FUNCTION__, $data);
}
return $data;
}

I wrote a function that does the job, and also converts all json strings to arrays too. This works pretty fine for me.
我编写了一个函数来完成这项工作，并将所有 json 字符串也转换为数组。这对我来说很好用。
function is_json($string) {
// php 5.3 or newer needed;
json_decode($string);
return (json_last_error() == JSON_ERROR_NONE);
}
function objectToArray($objectOrArray) {
// if is_json -> decode :
if (is_string($objectOrArray) && is_json($objectOrArray)) $objectOrArray = json_decode($objectOrArray);
// if object -> convert to array :
if (is_object($objectOrArray)) $objectOrArray = (array) $objectOrArray;
// if not array -> just return it (probably string or number) :
if (!is_array($objectOrArray)) return $objectOrArray;
// if empty array -> return [] :
if (count($objectOrArray) == 0) return [];
// repeat tasks for each item :
$output = [];
foreach ($objectOrArray as $key => $o_a) {
$output[$key] = objectToArray($o_a);
}
return $output;
}

This is an old question, but I recently ran into this and came up with my own solution.
这是一个老问题，但我最近遇到了这个问题并提出了我自己的解决方案。
array_walk_recursive($array, function(&$item){
if(is_object($item)) $item = (array)$item;
});
Now if $arrayis an object itself you can just cast it to an array before putting it in array_walk_recursive:
现在，如果$array是一个对象本身，您可以在将其放入之前将其转换为数组array_walk_recursive：
$array = (array)$object;
array_walk_recursive($array, function(&$item){
if(is_object($item)) $item = (array)$item;
});
And the mini-example:
和小例子：
array_walk_recursive($array,function(&$item){if(is_object($item))$item=(array)$item;});
In my case I had an array of stdClass objects from a 3rd party source that had a field/property who's value I need to use as a reference to find it's containing stdClass so I can access other data in that element. Basically comparing nested keys in 2 data sets.
在我的情况下，我有一个来自 3rd 方源的 stdClass 对象数组，该对象有一个字段/属性，我需要将其值用作引用以查找它包含 stdClass，以便我可以访问该元素中的其他数据。基本上比较 2 个数据集中的嵌套键。
I have to do this many times, so I didn't want to foreach over it for each item I need to find. The solution to that issue is usually array_column, but that doesn't work on objects. So I did the above first.
我必须多次这样做，所以我不想为我需要找到的每个项目都遍历它。该问题的解决方案通常是array_column，但这不适用于对象。所以我先做了上面的。
Cheers!
干杯!

Just in case you came here as I did and didn't find the right answer for your situation, this modified version of one of the previous answers is what ended up working for me:
以防万一你像我一样来到这里并且没有找到适合你情况的正确答案，这个先前答案之一的修改版本最终对我有用：
protected function objToArray($obj)
{
// Not an object or array
if (!is_object($obj) && !is_array($obj)) {
return $obj;
}
// Parse array
foreach ($obj as $key => $value) {
$arr[$key] = $this->objToArray($value);
}
// Return parsed array
return $arr;
}
The original value is a JSON string. The method call looks like this:
原始值是一个 JSON 字符串。方法调用如下所示：
$array = $this->objToArray(json_decode($json, true));
