Sending HTML Code Through JSON
提问by Hirvesh
I've got a php script which generates HTML content. Is there a way to send back that HTML content through JSON to my webpage from the php script?
我有一个生成 HTML 内容的 php 脚本。有没有办法通过 JSON 将 HTML 内容从 php 脚本发送回我的网页？

Yes, you can use json_encodeto take your HTML string and escape it as necessary.
是的，您可以使用json_encode来获取 HTML 字符串并根据需要对其进行转义。
Note that in JSON, the top level item mustbe an array or object(that's not true anymore), it cannot just be a string. So you'll want to create an object and make the HTML string a property of the object (probably the only one), so the resulting JSON looks something like:
请注意，在JSON 中，顶级项目必须是一个数组或对象（这不再是真的），它不能只是一个字符串。因此，您需要创建一个对象并使 HTML 字符串成为该对象的一个属性（可能是唯一的一个），因此生成的 JSON 类似于：
{"html": "<p>I'm the markup</p>"}

Do Like this
这样做
1st put all your HTML content to array, then do json_encode
1st 将所有 HTML 内容放入数组，然后执行 json_encode
$html_content="<p>hello this is sample text";
$json_array=array(
'content'=>50,
'html_content'=>$html_content
);
echo json_encode($json_array);

All string data must be UTF-8 encoded.
所有字符串数据都必须采用 UTF-8 编码。
$out = array(
'render' => utf8_encode($renderOutput),
'text' => utf8_encode($textOutput)
);
$out = json_encode($out);
die($out);

Just to expand on @T.J. Crowder's answer.
只是为了扩展@TJ Crowder 的回答。
json_encodedoes well with simple html strings, in my experience however json_encodeoften becomes confused by, (or it becomes quite difficult to properly escape) longer complex nested html mixed with php. Two options to consider if you are in this position are: encoding/decoding the markup first with something like [base64_encode][1]/ decode(quite a bit of a performance hit), or (and perhaps preferably) be more selective in what you are passing via json, and generate the necessary markup on the client side instead.
json_encode处理简单的 html 字符串效果很好，但根据我的经验，json_encode经常被（或者很难正确转义）与 php 混合的更长的复杂嵌套 html 混淆。如果您处于此位置，要考虑的两个选项是：首先使用[base64_encode][1]/ decode 之类的东西对标记进行编码/解码（对性能影响很大），或者（也许最好）对通过 json 传递的内容更具选择性，并在客户端生成必要的标记。

You can send it as a String, why not. But you are probably missusing JSON here a bit since as far as I understand the point is to send just the data needed and wrap them into HTML on the client.
您可以将其作为字符串发送，为什么不呢。但是您可能在这里有点误用 JSON，因为据我所知，重点是仅发送所需的数据并将它们包装到客户端上的 HTML 中。

In PHP:
在 PHP 中：
$data = "<html>....";
exit(json_encode($data));
Then you should use AJAX to retrieve the data and do what you want with it. I suggest using JQuery: http://api.jquery.com/jQuery.getJSON/
然后你应该使用 AJAX 来检索数据并用它做你想做的事。我建议使用 JQuery：http: //api.jquery.com/jQuery.getJSON/
