$data包含下面的html，它可以是带有单引号双引号斜杠的html，有时只是一个简单的文本。

呈现它显示的编码 html 时出现问题 （
u003Cpu003E）这些类型的字符。
使用json_decode渲染
$agent_info = @json_decode( $data );
echo '<pre>';print_r($agent_info);echo '</pre>';
输出

在数据属性中使用 JSON 编码时，规范不是使用 JSON 编码选项进行转义，而是使用 HTML 属性转义的标准机制。在PHP中，这可能是诸如htmlspecialchars或htmlspecialentities之类的东西，具有HTML上下文的适当选项。
使用 JSON 编码在 javascript 中嵌入数据时，您只需要JSON_HEX_TAG。
不要引用我的话，因为可能会遗漏一些场景或方面。浏览器习惯于有允许绕过某些约束的怪癖。另一方面，我不认为为了以防万一而任意逃跑是合理的。
您可以传递JSON_UNESCAPED_UNICODE以输出原始 UTF8 而不是转义。不过，一些解析器反对这一点。您应该检查标准对此有何说明。
