在 php 中使用 file_get_content 时如何保留缩进? [英] How can I retain indentation while using file_get_content with php?

问题描述

我在 php 中使用 file_get_contents 函数来获取站点的内容.问题是，在我从中获取信息的站点上，信息被整齐地缩进，但当我检索信息时，它会丢失所有缩进.

我使用的代码是:

如果您访问此处的原始站点，您可以看到信息是如何设置的:

<代码>{"id": "220439","name": "布雷特泰勒","first_name": "布雷特","last_name": "泰勒","link": "https://www.facebook.com/btaylor","用户名": "btaylor","性别": "男","locale": "en_US"}

在我的网站上，抓取信息后，它看起来像这样:

{"id":"220439","name":"Bret Taylor","first_name":"Bret","last_name":"Taylor","link":"http:\/\/www.facebook.com\/btaylor","username":"btaylor","gender":"male","locale":"en_US"}

如何保持缩进?

提前致谢！

顺便说一下，链接和信息来自 Facebook 的示例页面，并非真实信息.

解决方案

这与 file_get_contents.它完全取决于页面的 Content-Type.原始是纯文本，而您的网站输出 HTML.

您可以使用:

 header("Content-Type: text/plain");

或者保留 HTML 类型，但将输出包装在 pre 标签中:

 echo "
$file
";

由于您可能想重用镜像的 JSON 输出，我会选择第一个选项.(但是 application/json 类型可能更合适.不知道你为什么要以固定格式呈现它.)

I am using the file_get_contents function in php to get the contents of a site. The problem is that on the site I am grabbing information from, the information is neatly indented, yet when I retrieve the information it looses all indentation.

The code I am using is:

<?php
$url = "https://graph.facebook.com/btaylor";
$file = file_get_contents($url);
echo "$file";
?>

If you go to the original site here, you can see how the information is set up as:

{
   "id": "220439",
   "name": "Bret Taylor",
   "first_name": "Bret",
   "last_name": "Taylor",
   "link": "https://www.facebook.com/btaylor",
   "username": "btaylor",
   "gender": "male",
   "locale": "en_US"
}

yet on my site, after grabbing the information it looks like this:

{"id":"220439","name":"Bret Taylor","first_name":"Bret","last_name":"Taylor","link":"http:\/\/www.facebook.com\/btaylor","username":"btaylor","gender":"male","locale":"en_US"}

How can I keep the indentation?

Thanks in advance!

By the way, the link and information is from a sample page from Facebook, and not real information.

解决方案

This has nothing to do with file_get_contents. It solely depends on the Content-Type of your page. The original is plain text, while your site outputs HTML.

You can either use:

 header("Content-Type: text/plain");

Or keep the HTML type but wrap your output in pre tags:

 echo "<pre>$file</pre>";

Since you possibly want to reuse that mirrored JSON output, I would go for the first option. (But then an application/json type might be more appropriate. Not sure why you want to present it with fixed formatting anyway.)
