stdClass Object
(
[0] => stdClass Object
(
[one] => aaa
[two] => sss
)
[1] => stdClass Object
(
[one] => ddd
[two] => fff
)
[2] => stdClass Object
(
[one] => ggg
[two] => hhh
)
}
and i mustget this with keys, for example:
我必须用钥匙得到这个，例如：
$var = $stdClass[0];
but i have error:
但我有错误：
Fatal error: Cannot use object of type stdClass as array in
致命错误：不能使用 stdClass 类型的对象作为数组
Is possible parse this stdClass to array and use this with keys?
是否可以将此 stdClass 解析为数组并将其与键一起使用？

Cast it to an array:
将其转换为数组：
$array = (array)$stdClass;

If you're using json_decodeto convert that JSON string into an object, you can use the second parameter json_decode($string, true)and that will convert the object to an associative array.
如果json_decode要将该 JSON 字符串转换为对象，则可以使用第二个参数json_decode($string, true)，这会将对象转换为关联数组。
If not, what everybody else has said and just type cast it
如果没有，其他人都说了什么，只需输入即可
$array = (array) $stdClass;
$array = (array) $stdClass;

Your problem is probably solved since asking, but for reference, quick uncle-google answer:
自问以来，您的问题可能已解决，但作为参考，谷歌叔叔快速回答：
function objectToArray($d) {
if(is_object($d)) {
$d = get_object_vars($d);
}
if(is_array($d)) {
return array_map(__FUNCTION__, $d); // recursive
} else {
return $d;
}
}

Cast it
投射它
$array = (array) $stdObject;
回答by Mike Mackintosh
Of course you can typecast, $var = (array) $obj;, but I would suggest ArrayAccessto your class.
当然你可以打字，$var = (array) $obj;但我会建议ArrayAccess你的班级。
By using ArrayAccess, you can then treat your objects and data as if it was an array, or natively as an object.
通过使用ArrayAccess，您可以将您的对象和数据视为一个数组，或者本机将其视为一个对象。

Cast it into an array. Currently it is not readable to PHP as an array.
将其转换为数组。目前它不能作为数组被 PHP 读取。
$array = (array)$stdClass;

If you have an nested array you can used json_encodeand json_decodeto convert the whole object to an array:
如果你有一个嵌套的数组，你可以使用json_encode和json_decode整个对象转换为数组：
$result = json_decode(json_encode($source), JSON_OBJECT_AS_ARRAY);
回答by Vladimir verleg
This one worked for me, The decoding and encoding makes for a regular array
这个对我有用，解码和编码构成了一个常规数组
$array = json_decode(json_encode($object), True);
$array = json_decode(json_encode($object), True);

function load_something () : \stdClass {
$result = new \stdClass();
$result->varA = 'this is the value of varA';
$result->varB = 'this is the value of varB';
$result->varC = 'this is the value of varC';
return $result;
}
$result = load_something();
echo ($result instanceof stdClass)?'Object is stdClass':'Object is not stdClass';
echo PHP_EOL;
print_r($result);
//directly extract a variable from stdClass
echo PHP_EOL . 'varA = ' . ($result->varA);
//convert to array, then extract
$array = (array)$result;
echo PHP_EOL . 'varA = ' . $array['varA'];
