json_encode / json_decode之后和之前

$data包含在html下方，它可以是帶有單引號，雙引號斜杠或有時只是簡單文本的html。

<p>Ahmed Khan is a commercial consultant, a B.School MBA with flair of consulting businesses.

呈現此編碼的html時出現問題，該html顯示（ u003Cpu003E ）這些類型的字符。

用json_decode渲染

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

在數據屬性中使用JSON編碼時，規范是不要使用JSON編碼選項轉義，而是轉義HTML屬性的標准機制。 在PHP中，可能帶有諸如htmlspecialchars或htmlspecialentities之類的內容，並且帶有HTML上下文的適當選項。

使用JSON編碼在javascript中嵌入數據時，您只需要JSON_HEX_TAG。

盡管可能會遺漏某些場景或方面，但不要在此引用我的信息。 瀏覽器有一個習慣，即可以繞過某些限制的習慣。 另一方面，我認為以防萬一是合理的。

您可以傳遞JSON_UNESCAPED_UNICODE來輸出原始UTF8，而不是進行轉義。 不過，一些解析器對此表示反對。 您應該檢查標准對此要說些什么。
