得到json_encode不转义html实体 [英] getting json_encode to not escape html entities

问题描述

我从我的PHP服务器发送 json_encoded 数据到iPhone应用程序。包含html实体的字符串，如'&'由 json_encode 转义，并作为& ; amp; 。

I send json_encoded data from my PHP server to iPhone app. Strings containing html entities, like '&' are escaped by json_encode and sent as &.

我想做两件事之一：

• make json_encode 不转义html实体。 Doc说正常模式不应该逃避它，但它不适合我。任何想法？

• make json_encode not escape html entities. Doc says 'normal' mode shouldn't escape it but it doesn't work for me. Any ideas?

使iPhone应用程序可以廉价地转义html实体。我现在想到的唯一方法是调用一个非常昂贵的 XML / HTML解析器。任何更便宜的建议？

make the iPhone app un-escape html entities cheaply. The only way I can think of doing it now involves spinning up a XML/HTML parser which is very expensive. Any cheaper suggestions?

谢谢！

推荐答案

PHP 5.3和PHP 5.2都不会触及HTML实体。

Neither PHP 5.3 nor PHP 5.2 touch the HTML entities.

您可以 test ，并附上以下代码：

You can test this with the following code:

<?php
header("Content-type: text/plain"); //makes sure entities are not interpreted
$s = 'A string with &amp; &#x6F8 entities';
echo json_encode($s);

你会看到PHP做的唯一的事情是在字符串周围添加双引号。

You'll see the only thing PHP does is to add double quotes around the string.
