json_encode() 转义正斜杠 [英] json_encode() escaping forward slashes

问题描述

我正在从 Instagram 中提取 JSON:

I'm pulling JSON from Instagram:

$instagrams = json_decode($response)->data;

然后将变量解析成PHP数组来重构数据，然后重新编码并缓存文件:

Then parsing variables into a PHP array to restructure the data, then re-encoding and caching the file:

file_put_contents($cache,json_encode($results));

当我打开缓存文件时，我所有的正斜杠/"都被转义了:

When I open the cache file all my forward slashes "/" are being escaped:

我从搜索中得知 json_encode() 会自动执行此操作...有没有办法禁用它?

I gather from my searches that json_encode() automatically does this...is there a way to disable it?

推荐答案

有没有办法禁用它?

是的，您只需要使用 JSON_UNESCAPED_SLASHES 标志.

Yes, you only need to use the JSON_UNESCAPED_SLASHES flag.

json_encode($str, JSON_UNESCAPED_SLASHES);

如果您手头没有 PHP 5.4，请选择众多现有函数中的一个并根据您的需要修改它们，例如http://snippets.dzone.com/posts/show/7487(存档副本).

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).

示例演示

<?php
/*
 * Escaping the reverse-solidus character ("/", slash) is optional in JSON.
 *
 * This can be controlled with the JSON_UNESCAPED_SLASHES flag constant in PHP.
 *
 * @link http://stackoverflow.com/a/10210433/367456
 */    

$url = 'http://www.example.com/';

echo json_encode($url), "
";

echo json_encode($url, JSON_UNESCAPED_SLASHES), "
";

示例输出:

"http://www.example.com/"
"http://www.example.com/"
