Question

JSON帖子从webservice返回格式化字符串中的答案（例如，我有一个带搜索框的网站，无论我在搜索框中输入什么，我想要一个格式化的字符串，而不是它给我一个答案的转储，这是没有格式化）

以下是带有JSON的HTML / PHP代码：

 <!-- Start of Search Wrapper -->
            <div class = "imageContainer">
            <a href="#"><img src="images/" title="logo" /></a>

运行时提取：

 {"question":{"qclasslist":[{"value":"DESCRIPTIVE"},{"value":"FOCUSLESS"},{"value":"DEFINITION"}],"focuslist":[{"value":"brent"}],"latlist":[{"value":"brent"}],"evidencelist":[{},{"value":"0.04949565976858139","text":" To achieve Community Care BLAHBLAHBLAH.........ETC

我真正想要的是字符串返回（实现社区护理BLAHBLAHBLAH ......... ETC）

我改进了代码并注释掉了$ extract，让我很困惑。我还将echo代码更改为print_r（json_decode（$ result））;

运行时提取：

 stdClass Object

（ [问题] =＆gt; stdClass对象（ [qclasslist] =＆gt;排列（ [0] =＆gt; stdClass对象（ [value] =＆gt;描述性）

                [1] => stdClass Object
                    (
                        [value] => FOCUSLESS
                    )

            )

        [evidencelist] => Array
            (
                [0] => stdClass Object
                    (
                        [value] => 0.48106712102890015
                        [text] => BLAH BLAH BLAH BLAH
                        [id] => 001
                        [title] => What is non-medical prescribing?
                        [document] => Post/question/djncjabuvas
                        [copyright] => "URL"
                        [termsOfUse] => "URL"

我越来越接近我的目标，只需要提取[Title]和[text]字段，这只是一个简单的问答概念。非常感谢您的帮助。我听说格式化答案会有所帮助，但不确定我是否正确宣布它。

Answer 1

很难判断它是对象还是数组，但尝试将<?php echo json_encode($result, true)?>替换为<?php echo $result->text; ?>或<?php echo $result['text']; ?>。

如果它们不起作用，请尝试将其替换为：<?php var_dump($result); ?>并发布结果。

修改

试试这个：但很难看到对象的结构...... 你真的只需要向我展示一个格式正确的对象，我可以给出明确的答案。

$result->question->evidencelist[0]->text
