从包含 stdClass PHP 对象的数组中获取值

Question

我正在从 Facebook Graph API 获取信息，returns 一个包含多个 stdClass 对象的数组。我可以轻松读取 "top" 级别的项目，例如下面示例中的 $myGraph['id'] = 123111193。

任何人都可以告诉我如何从 stdClass 对象获取数据，例如以下使用 print_r() 创建的示例中的学校名称吗？

    Array
    (
        [id] => 123111193
        [education] => Array
    (
        [0] => stdClass Object
            (
                [school] => stdClass Object
                    (
                        [id] => 108177302537907
                        [name] => State College Area High School
                    )

                [type] => High School
                [year] => stdClass Object
                    (
                        [id] => 117615364954534
                        [name] => 1975
                    )

            )

        [1] => stdClass Object
            (
                [concentration] => Array
                    (
                        [0] => stdClass Object
                            (
                                [id] => 193334910691838
                                [name] => Individual and Family Studies
                            )

                    )

                [school] => stdClass Object
                    (
                        [id] => 113618111985274
                        [name] => Pennsylvania State University
                    )

Answer 1

<?php

foreach($mainArray['education'] as $edObj) 
{
     echo $edObj->school->name;
}

Answer 2

没什么特别的。如果您有一个名为 $foo 的标准对象，并且它有一个 $bar 成员，那么您将其称为 $foo->bar。示例：

foreach ($mainArray["education"] as $value) {
    echo $value->school->name;
}
