json_encode() escaping forward slashes
提问by Michael C.
I'm pulling JSON from Instagram:
我正在从 Instagram 中提取 JSON：
$instagrams = json_decode($response)->data;
$instagrams = json_decode($response)->data;
Then parsing variables into a PHP array to restructure the data, then re-encoding and caching the file:
然后将变量解析为 PHP 数组以重构数据，然后重新编码和缓存文件：
file_put_contents($cache,json_encode($results));
file_put_contents($cache,json_encode($results));
When I open the cache file all my forward slashes "/" are being escaped:
当我打开缓存文件时，我所有的正斜杠“/”都被转义了：

http:\/\/distilleryimage4.instagram.com\/410e7...
I gather from my searches that json_encode()automatically does this...is there a way to disable it?
我从我的搜索中收集json_encode()自动执行此操作...有没有办法禁用它？

有没有办法禁用它？
Yes, you only need to use the JSON_UNESCAPED_SLASHESflag.
是的，您只需要使用JSON_UNESCAPED_SLASHES标志。

!important之前阅读：https: //stackoverflow.com/a/10210367/367456（知道你在处理什么 - 了解你的敌人）
json_encode($str, JSON_UNESCAPED_SLASHES);
If you don't have PHP 5.4 at hand, pick one of the many existing functions and modify them to your needs, e.g. http://snippets.dzone.com/posts/show/7487 (archived copy).
如果您手头没有 PHP 5.4，请选择众多现有功能之一并根据您的需要修改它们，例如http://snippets.dzone.com/posts/show/7487 (archived copy)。

/*
* Escaping the reverse-solidus character ("/", slash) is optional in JSON.
*
* This can be controlled with the JSON_UNESCAPED_SLASHES flag constant in PHP.

*/
$url = 'http://www.example.com/';
echo json_encode($url), "\n";
echo json_encode($url, JSON_UNESCAPED_SLASHES), "\n";
Example Output:
示例输出：
"http:\/\/www.example.com\/"
"http://www.example.com/"

Yes, but don't - escaping forward slashes is a good thing. When using JSON inside <script>tags it's necessary as a </script>anywhere - even inside a string - will end the script tag.
是的，但不要逃避正斜杠是一件好事。在<script>标签内使用 JSON时，有必要在</script>任何地方 - 甚至在字符串内 - 将结束脚本标签。
Depending on where the JSON is used it's not necessary, but it can be safely ignored.
根据使用 JSON 的位置，它不是必需的，但可以安全地忽略它。

On the flip side, I was having an issue with PHPUNIT asserting urls was contained in or equal to a url that was json_encoded -
另一方面，我遇到了 PHPUNIT 断言 url 包含在或等于 json_encoded 的 url 中的问题 -
my expected:
我的预期：
http://localhost/api/v1/admin/logs/testLog.log
http://localhost/api/v1/admin/logs/testLog.log
would be encoded to:
将被编码为：
http:\/\/localhost\/api\/v1\/admin\/logs\/testLog.log
http:\/\/localhost\/api\/v1\/admin\/logs\/testLog.log
If you need to do a comparison, transforming the url using:
如果您需要进行比较，请使用以下方法转换 url：
addcslashes($url, '/')
addcslashes($url, '/')
allowed for the proper output during my comparisons.
在我的比较过程中允许正确的输出。

我不得不遇到这样的情况，简单地说，
