我的html由php json_encode编码，json常量

使用json_encode( $data, JSON_HEX_QUOT | JSON_HEX_TAG )

之后＆amp;在json_encode / json_decode

之前

{"agent_designation":"Agent","agent_desc":"\u003Cp\u003EAhmed Khan is a commercial consultant, a B.School MBA with flair of consulting businesses.

$data包含html，它可以是单引号双引号斜杠的html，有时只是一个简单的文本。

<p>Ahmed Khan is a commercial consultant, a B.School MBA with flair of consulting businesses. With insightful perception of end user concerns to methodical compliance in consulting Investor groups, his analytical perspective & proactive approach gave significant recognition.

在渲染此编码的html时会出现问题（u003Cpu003E）这些类型的角色。

使用json_decode

进行渲染

        $agent_info = @json_decode( $data );
        echo '<pre>';print_r($agent_info);echo '</pre>';

输出

u003Cpu003EAhmed Khan is a commercial consultant, a B.School MBA with flair of consulting businesses. With insightful perception of end user concerns to methodical compliance in consulting Investor groups, his analytical perspective & proactive approach gave significant recognition. His transparency of information and numbers has gained him virtual clients internationally.

His consultation justifies a propertyu2019s relevance, while offering holistic solutions from cost to return on investments.u003C/pu003E

在数据属性中使用JSON编码时，规范是不使用JSON编码选项进行转义，而是转义HTML属性的标准机制。在PHP中，可能是诸如htmlspecialchars或htmlspecialentities之类的，具有适用于HTML上下文的选项。

使用JSON编码在javascript中嵌入数据时，您应该只需要JSON_HEX_TAG。

不要引用我的话，因为可能会遗漏一些情景或方面。浏览器习惯于有怪癖，允许双向某些约束。另一方面，我不认为随意逃避以防万一是合理的。

您可以传递JSON_UNESCAPED_UNICODE来输出原始UTF8而不是转义。一些解析器反对这一点。你应该检查一下标准的含义。

如何解码用JSON_HEX_QUOT |编码的html字符串JSON_HEX_TAG
