我将如何读这阵列（; stdClass的对象＆QUOT;） [英] How would I read this array ("stdClass Object")

问题描述

我使用的是Quizlet API 2.0，而我pretty新本

我读东西值（S），像这样怎么办：

  stdClass的对象（[ID] =＆GT; 102269 [名] =＆GT;！与猫学习西班牙语[set_count] =＆GT; 3 [USER_COUNT] =＆GT; 10 CREATED_DATE] =＆GT; 1308035691【is_public] =＆GT; 1 [has_password] =＆GT; has_​​access] =＆GT; 1 [has_discussion] =＆GT; 1 [member_add_sets] =＆GT; 1 [说明] =＆gt;这集是专为西班牙烧录卡套有关猫的图像作为集定义[设置] =方式＆gt;阵列（[0] =＆GT; stdClass的对象（[ID] =＆GT; 6081999 [URL] =＆GT; http://quizlet.com/6081999 /课-4与 -  catsdogs闪存卡/ [标题] =＆GT;第4课（带猫+狗）[CREATED_BY] =＆GT; wsvincent [term_count] =＆GT; 33 [CREATED_DATE] =＆GT; 1311984796【MODIFIED_DATE ] =＆GT; 1312490710【has_images] =＆GT; 1 [主题] =＆GT;数组（[0] =＆GT;西班牙语猫犬）[知名度] =＆GT;公共 =基团[has_access] =＆GT; 1）[1] =＆GT; stdClass的对象（[ID] =＆GT; 5855751 [URL] =＆GT; http://quizlet.com/5855751/paso-a-paso-book-1-chapter-4-flash-卡/ [标题] =＆GT;埃尔帕索埃尔帕索一书1章4 CREATED_BY] =＆GT; catdawg426 [term_count] =＆GT; 30 CREATED_DATE] =＆GT; 1307761267 [MODIFIED_DATE] =＆GT; 1307819129 [has_images] =＆GT; 1 [主题] =＆GT;阵列（[0] =＆GT;西班牙语）[知名度] =＆GT;公共 =＆GT; only_me [has_access] =＆GT; 1）[2] =＆GT; stdClass的对象（[ID] =＆GT; 5873819 [URL] =＆GT; http://quizlet.com/5873819/los-gatos-de-viaje-flash-cards/ [标题] =＆GT;洛斯加托斯德VIAJE [！ CREATED_BY] =＆GT; tiffreja [term_count] =＆GT; 21 [CREATED_DATE] =＆GT; 1307996657【MODIFIED_DATE] =＆GT; 1307996796【has_images] =＆GT; 1 [主题] =＆GT;数组（[0] =＆GT;西班牙语[ 1] =＆GT;语言[2] =＆GT;外商）[知名度] =＆GT;公共 =＆GT; only_me [has_access] =＆GT; 1））[会员] =＆GT;阵列（[0] =＆GT; stdClass的对象（[用户名] =＆GT; philfreo [作用] =＆GT;创作者[email_notification] =＆GT; 1）[1] =＆GT; stdClass的对象（[用户名] =＆GT; milkncookies [作用] =＆GT;成员[email_notification] =＆GT; 1）[2] =＆GT; stdClass的对象（[用户名] =＆GT; Icypaw [作用] =＆GT;成员[email_notification] =＆GT;）[3] =＆GT; stdClass的对象（[用户名] =＆GT; luckycat10 [作用] =＆GT;成员[email_notification] =＆GT;）[4] =＆GT; stdClass的对象（[用户名] =＆GT; jeffchan [作用] =＆GT;成员[email_notification] =＆GT;）[5] =＆GT; stdClass的对象（[用户名] =＆GT; catchdave [作用] =＆GT;成员[email_notification] =＆GT; 1）[6] =＆GT; stdClass的对象（[用户名] =＆GT; tiffreja [作用] =＆GT;成员[email_notification] =＆GT; 1）[7] =＆GT; stdClass的对象（[用户名] =＆GT; catdawg426 [作用] =＆GT;成员[email_notification] =＆GT; 1）[8] =＆GT; stdClass的对象（[用户名] =＆GT; ihaque [作用] =＆GT;成员[email_notification] =＆GT; 1）[9] =＆GT; stdClass的对象（[用户名] =＆GT; jalenack [作用] =＆GT;会员[email_notification] =＆GT; 1）））
 

举例来说，如果我想要得到的第一套，学习西班牙语与猫的名字，我怎么通过可变呼应呢？

这已经是JSON转换为一个数组，我认为：

  $数据= json_de code（$ JSON）;
 

解决方案

您的对象不是一个数组，而是很好，一个对象。因此，使用 - ＆GT; 操作符来访问它的属性。

 回声$数据 - ＆GT;名;
 

它包含一个属性，它本身是其他对象的阵列。例如，为了获得ID 6081999的网址，你会怎么做：

 回声$数据 - ＆GT;设置[0]  - ＆GT;网址;

I am using the Quizlet API 2.0, and I am pretty new to this

How do I read a value(s) from something like this:

stdClass Object ( [id] => 102269 [name] => Learn Spanish with Cats! [set_count] => 3 [user_count] => 10 [created_date] => 1308035691 [is_public] => 1 [has_password] => [has_access] => 1 [has_discussion] => 1 [member_add_sets] => 1 [description] => This set is exclusively for Spanish flashcard sets with relevant cat images as the set definitions. [sets] => Array ( [0] => stdClass Object ( [id] => 6081999 [url] => http://quizlet.com/6081999/lesson-4-with-catsdogs-flash-cards/ [title] => Lesson 4 (with cats+dogs) [created_by] => wsvincent [term_count] => 33 [created_date] => 1311984796 [modified_date] => 1312490710 [has_images] => 1 [subjects] => Array ( [0] => spanish cats dogs ) [visibility] => public [editable] => groups [has_access] => 1 ) [1] => stdClass Object ( [id] => 5855751 [url] => http://quizlet.com/5855751/paso-a-paso-book-1-chapter-4-flash-cards/ [title] => Paso a Paso Book 1 Chapter 4 [created_by] => catdawg426 [term_count] => 30 [created_date] => 1307761267 [modified_date] => 1307819129 [has_images] => 1 [subjects] => Array ( [0] => spanish ) [visibility] => public [editable] => only_me [has_access] => 1 ) [2] => stdClass Object ( [id] => 5873819 [url] => http://quizlet.com/5873819/los-gatos-de-viaje-flash-cards/ [title] => Los Gatos de Viaje! [created_by] => tiffreja [term_count] => 21 [created_date] => 1307996657 [modified_date] => 1307996796 [has_images] => 1 [subjects] => Array ( [0] => spanish [1] => language [2] => foreign ) [visibility] => public [editable] => only_me [has_access] => 1 ) ) [members] => Array ( [0] => stdClass Object ( [username] => philfreo [role] => creator [email_notification] => 1 ) [1] => stdClass Object ( [username] => milkncookies [role] => member [email_notification] => 1 ) [2] => stdClass Object ( [username] => Icypaw [role] => member [email_notification] => ) [3] => stdClass Object ( [username] => luckycat10 [role] => member [email_notification] => ) [4] => stdClass Object ( [username] => jeffchan [role] => member [email_notification] => ) [5] => stdClass Object ( [username] => catchdave [role] => member [email_notification] => 1 ) [6] => stdClass Object ( [username] => tiffreja [role] => member [email_notification] => 1 ) [7] => stdClass Object ( [username] => catdawg426 [role] => member [email_notification] => 1 ) [8] => stdClass Object ( [username] => ihaque [role] => member [email_notification] => 1 ) [9] => stdClass Object ( [username] => jalenack [role] => member [email_notification] => 1 ) ) )

For instance, if I want to get the name of that first set, "Learn Spanish with Cats", how do I echo it via variable?

It already converts the JSON to an array I think:

$data = json_decode($json);

解决方案

Your object is not an array, but rather, well, an Object. So use the -> operator to access its properties:

echo $data->name;

It contains a property which itself is an array of additional objects. For example, to get the URL of id 6081999, you would do:

echo $data->sets[0]->url;
// http://quizlet.com/6081999/lesson-4-with-catsdogs-flash-cards/
