[英]Get stdClass Object by value
Given this stdClass structure...鉴于这个 stdClass 结构......
[RecentAchievements] => stdClass Object
(
[1446] => stdClass Object
(
[3319] => stdClass Object
(
[ID] => 3319
[GameID] => 1446
[Title] => Hello World!
[Description] => Complete World 1-1
[Points] => 15
[BadgeName] => 03909
[IsAwarded] => 1
[DateAwarded] => 2013-10-20 19:35:46
)
I need to check the objects inside 3319, like "Title", so it'd be like:我需要检查 3319 里面的对象,比如“标题”,所以它就像:
$data->RecentAchievements->$gameid->ACHVIDHERE->Title;
To get the $gameid, it came from other object (RecentlyPlayed), this way:要获取 $gameid,它来自其他对象 (RecentlyPlayed),如下所示:
[RecentlyPlayed] => Array
(
[0] => stdClass Object
(
[GameID] => 1446
[ConsoleID] => 7
[ConsoleName] => NES
[Title] => Super Mario Bros
[LastPlayed] => 2013-10-20 21:38:22
[ImageIcon] => /Images/000385.png
[ImageTitle] => /Images/000272.png
[ImageIngame] => /Images/000387.png
[ImageBoxArt] => /Images/000275.png
)
)
$gameid = $data3->RecentlyPlayed['0']->GameID;
API don't let me use the same RecentlyPlayed to get the achievement ID, i have to extract it from RecentAchievements. API 不允许我使用相同的最近播放来获取成就 ID,我必须从最近的成就中提取它。 Is it possible?
有可能吗?
If you're just after the first achievement for that particular game, you could use this hack:如果您刚刚获得该特定游戏的第一个成就,则可以使用以下技巧:
$firstAchievement = reset($data->RecentAchievements->$gameid);
$title = $firstAchievement->Title;
The API is probably giving you a JSON response, so you may also want to consider this: API 可能会为您提供 JSON 响应,因此您可能还需要考虑这一点:
$data = json_decode($response, true);
^^^^
The second parameter true
turns the JavaScript objects into PHP arrays, which in most cases makes it easier to handle them, eg第二个参数
true
将 JavaScript 对象转换为 PHP 数组,这在大多数情况下更容易处理它们,例如
$firstAchievement = reset($data['RecentAchievements'][$gameid]);
$title = $firstAchievement['Title'];
You can use complex curly notation to reference dynamic properties of an object您可以使用复杂的卷曲符号来引用对象的动态属性
$data->RecentAchievements->{$gameid}->{$someotherid}->Title;
This should give you Hello World!
这应该会给你
Hello World!
, given $gameid
== 1446
and $someotherid
== 3319
, 给定
$gameid
== 1446
和$someotherid
== 3319
