Converting array and objects in array to pure array
提问by Thompson
My array is like:
我的数组是这样的：
Array
(
[0] => stdClass Object
(
[id] => 1
[name] => demo1
)
[1] => stdClass Object
(
[id] => 2
[name] => demo2
)
[2] => stdClass Object
(
[id] => 6
[name] => otherdemo
)
)
How can I convert the whole array (including objects) to a pure multi-dimensional array?
如何将整个数组（包括对象）转换为纯多维数组？

Have you tried typecasting?
你试过打字吗？
$array = (array) $object;
There is another trick actually
其实还有一个技巧
$json = json_encode($object);
$array = json_decode($json, true);
You can have more info here json_decodein the PHP manual, the second parameter is called assoc:
您可以json_decode在 PHP 手册中获得更多信息，第二个参数称为assoc：
assoc
When
TRUE, returned objects will be converted into associative arrays.
协会
当 时
TRUE，返回的对象将被转换为关联数组。
Which is exactly what you're looking for.
这正是您要寻找的。

You can use array_walkto convert every item from object to array:
您可以使用array_walk将每个项目从对象转换为数组：
function convert(&$item , $key)
{
$item = (array) $item ;
}
array_walk($array, 'convert');

Assuming you want to get to this pure array format:
假设您想使用这种纯数组格式：
Array
(
[1] => "demo1",
[2] => "demo2",
[6] => "otherdemo",
)
Then I would do:
然后我会这样做：
$result = array();
foreach ($array as $object)
{
$result[$object->id] = $object->name
}
(edit) Actually that's what I was looking for possibly not what the OP was looking for. May be useful to other searchers.
（编辑）实际上这就是我正在寻找的可能不是 OP 正在寻找的。可能对其他搜索者有用。

You should cast all objets, something like :
您应该投射所有对象，例如：
$result = array();
foreach ($array as $object)
{
$result[] = (array) $object
}

As you are using OOP, the simplest method would be to pull the code to convert itself into an array to the class itself, you then simply call this method and have the returned array populate your original array.
当您使用 OOP 时，最简单的方法是提取代码以将其自身转换为类本身的数组，然后您只需调用此方法并让返回的数组填充您的原始数组。
class MyObject {
private $myVar;
private $myInt;
public function getVarsAsArray() {
// Return the objects variables in any structure you need
return array($this->myVar,$this->myInt);
}
public function getAnonVars() {
// If you don't know the variables
return get_object_vars($this);
}
}
See: http://www.php.net/manual/en/function.get-object-vars.phpfor info on get_object_vars()
