我有一个带有“\\\ ”的字符串，我需要将其替换为“” str_replace失败 [英] I have a string with "\u00a0", and I need to replace it with "" str_replace fails

问题描述

我需要清理各种Microsoft Office套件应用程序（复制/粘贴）的字符串（ Excel ，访问和 Word ），每个都有自己的编码集。

I need to clean a string that comes (copy/pasted) from various Microsoft Office suite applications (Excel, Access, and Word), each with its own set of encoding.

我正在使用json_encode进行调试为了能够看到每一个编码的字符。

I'm using json_encode for debugging purposes in order to being able to see every single encoded character.

我可以用str_replace清理我发现的所有东西（\r \\\
），但是\\\ 我没有运气。

I'm able to clean everything I found so far (\r \n) with str_replace, but with \u00a0 I have no luck.

$string = '[e-mail]\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0;[e-mail]'; //this is the output from json_encode

$clean = str_replace("\u00a0", "",$string);

返回：

[e-mail]\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0;[e-mail]

完全一样;它完全忽略了\\\ 。

That is exactly the same; it completely ignores \u00a0.

有没有办法呢？另外，我感觉到我正在重塑轮子，是否有一个函数/类完全剥离了每个可能编码的可能性？

Is there a way around this? Also, I'm feeling I'm reinventing the wheel, is there a function/class that completely strips EVERY possibile char of EVERY possible encoding?

____EDIT____

在前两次回复之后，我需要澄清一点，我的示例工作，因为它是json_encode的输出，而不是实际的字符串！

After the first two replies I need to clarify that my example DOES work, because it's the output from json_encode, not the actual string!

推荐答案

当我复制/粘贴您的代码时，适用于我。尝试使用单引号替换 str_replace（）中的双引号，或者转义反斜杠（\\\\ ）。

Works for me, when I copy/paste your code. Try replacing the double quotes in your str_replace() with single quotes, or escaping the backslash ("\\u00a0").
