PHP URL 编码/解码表单字段中的漂亮引号%u2019
由于某种原因，在从文本表单向 php 提交类似 Jack's Spindle 的字符串后，我得到：
Jack%u2019s Spindle
This is not PHP 的 urlencode() 会做什么，即 Jack%92s+Spindle 或 rawurlencode() = Jack%92s%20Spindle
因此，urldecode() 和原始版本无法解码该字符串。此类字符串还有其他函数吗？
--
此外，Jack’s Spindle 将是对上述内容进行编码的 HTML 安全方式，但 urlencode() 和 raw* 会产生：Jack%26%238217%3Bs%20Spindle...
%u2019 来自哪里？它代表什么？你怎样才能把它恢复到那个无伤大雅的撇号呢？
For some reason, after submitting a string like this Jack’s Spindle from a text form to php, I get:
Jack%u2019s Spindle
This is not what PHP's urlencode() would do, which would be Jack%92s+Spindle
or rawurlencode() = Jack%92s%20Spindle
Thus, urldecode() and the raw version don't work to decode that string... Is there another function for such strings?
--
Also, Jack’s Spindle would be the HTML-safe way to encode the above, but urlencode() and raw* for that yields: Jack%26%238217%3Bs+Spindle and Jack%26%238217%3Bs%20Spindle respectively...
Where is the %u2019 coming from? What does it represent? How do you get it back to just that innoculous apostrophe?

好吧，只有你能告诉我们它来自哪里。您从哪里获取文本以及将其提交给哪些转换？我承认我还没有看到那种编码策略。
也就是说，它与 Javascript 编码 UTF-16 代码单元的方式非常相似：
\uXXXX，其中每个X代表一个十六进制字符。要将其转换为 HTML 实体，您可以执行以下操作：Well, only you can tell us from where that came from. From are you getting your text and which transformations is it being submitted to? I confess I haven't seen that encoding strategy yet.
That said, it's very similar to the way Javascript encodes UTF-16 code units:
\uXXXXwhere eachXrepresents a hexadecimal character. To convert it to HTML entities, you could do:preg_replace函数调用中的正则表达式应该有一个结束分隔符，即：preg_replace('/%u([a-fA-F0-9]{4})/', ' &#x\\1;', $string)。The Regular Expression in the
preg_replacefunction call should have an ending delimiter, i.e:preg_replace('/%u([a-fA-F0-9]{4})/', '&#x\\1;', $string).我有这样的问题。
当我通过 javascript/ajax 将变量发送到 php 脚本时，php 显示 %u2019 而不是引号等...
我是这样解决的：
- 在我的 javascript 脚本中，在发送之前将
escape(myvar)替换为encodeURIComponent(myvar)- 在我的 php 文件中，使用
$myvar=utf8_decode($_POST['myvar'])希望能有所帮助。
I had this kind of problem.
When i send variable via javascript/ajax to a php script, the php was displaying %u2019 instead of quote, etc...
I solved it like this :
- in my javascript script, replacing
escape(myvar)byencodeURIComponent(myvar)before sending- in my php file, using
$myvar=utf8_decode($_POST['myvar'])Hope thant can help.
