stdClass Object and array how to using php
提问by user638009
I'm trying to get the twelve ids that this structure shows:
我正在尝试获取此结构显示的十二个 ID：
stdClass Object
(
[checkins] => stdClass Object
(
[count] => 12
[items] => Array
(
[0] => stdClass Object
(
[venue] => stdClass Object
(
[id] => 4564654646456
.
.
I do:
我愿意：
$checkins = $fsObjUnAuth->get("/users/self/checkins");
$count = $checkins ->response->checkins->count; // so I can get 12
for( $i = 0; $i < $count; $i ++)
{
$a1[] = $checkins['items'][$i]['venue']['id']; //two tries
$a2[] = $checkins ->response->checkins->items->$i->venue->id;
echo $i; echo ": ";
echo $a1;echo"<br>";
echo $a2;echo"<br>"
}
But I get: Fatal error: Cannot use object of type stdClass as array in line..
但我得到：致命错误：无法将 stdClass 类型的对象用作数组中的行..
Please can someone show me how to do this?
请有人告诉我如何做到这一点？
Thanks a lot
非常感谢

You cannot access object members via the array subscript operator [].
您不能通过数组下标运算符访问对象成员[]。
You have to use the ->operator:
您必须使用->运算符：
$x = new StdClass();
$x->member = 123;
In your case you'll have to use a mixture, since you have an object ($checkins) with a member ($items) which is an array, which contains additional objects.
在您的情况下，您必须使用混合，因为您有一个对象 ( $checkins) 和一个成员 ( $items)，它是一个数组，其中包含其他对象。
$a1[] = $checkins->items[$i]->venue->id;

Here is a simple solution to converta stdClass Objectin array in php with function get_object_vars
这是一个简单的解决方案，用于在 php 中使用函数转换数组中的stdClass 对象get_object_vars
Look at : http://php.net/manual/fr/function.get-object-vars.php
看看：http: //php.net/manual/fr/function.get-object-vars.php
Ex :
前任 ：
debug($array);
$var = get_object_vars($array);
debug($var);
Or replace debugby print_r
或者替换debug为print_r
