I have a string with "\u00a0", and I need to replace it with "" str_replace fails
提问by 0plus1
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.
我需要清理来自（复制/粘贴）来自各种 Microsoft Office 套件应用程序（Excel、Access和Word）的字符串，每个应用程序都有自己的一组编码。
I'm using json_encode for debugging purposes in order to being able to see every single encoded character.
我将 json_encode 用于调试目的，以便能够看到每个编码的字符。
I'm able to clean everything I found so far (\r \n) with str_replace, but with \u00a0 I have no luck.
我可以用 str_replace 清理我目前找到的所有东西（\r\n），但是用 \u00a0 我没有运气。
$string = '[email protected]\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0;[email protected]'; //this is the output from json_encode
$clean = str_replace("\u00a0", "",$string);
returns:
返回：
[email protected]\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0;[email protected]
That is exactly the same; it completely ignores \u00a0.
那是完全一样的；它完全忽略了\u00a0。
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?
有没有解决的办法？另外，我觉得我在重新发明轮子，是否有一个函数/类可以完全去除所有可能编码的所有可能字符？

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!
在前两个回复之后，我需要澄清我的示例确实有效，因为它是 json_encode 的输出，而不是实际的字符串！

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").
当我复制/粘贴您的代码时，对我有用。尝试用str_replace()单引号替换双引号，或转义反斜杠 ( "\\u00a0")。

By combining ord()with substr()on my string containing \u00a0, I found the following curse to work:
通过ord()与substr()包含 \u00a0 的字符串结合，我发现以下诅咒有效：
$text = str_replace( chr( 194 ) . chr( 160 ), ' ', $text );

I just had the same problem. Apparently PHP's json_encode will return null for any string with a 'non-breaking space' in it.
我只是遇到了同样的问题。显然，对于任何包含“不间断空格”的字符串，PHP 的 json_encode 都会返回 null。
The Solution is to replace this with a regular space:
解决方案是将其替换为常规空间：
str_replace(chr(160),' ');
I hope this helps somebody - it took me an hour to figure out.
我希望这对某人有所帮助 - 我花了一个小时才弄明白。

A minor point: \u00a0 is actually a non-breaking space character, c.f. http://www.fileformat.info/info/unicode/char/a0/index.htm
一个小问题： \u00a0 实际上是一个不间断的空格字符，参见http://www.fileformat.info/info/unicode/char/a0/index.htm
So it might be more correct to replace it with " "
所以用“”替换它可能更正确

This one also works, i found somewhere
这个也有效，我在某处找到了
$str = trim($str, chr(0xC2).chr(0xA0));

This did the trick for me:
这对我有用：
$str = preg_replace( "~\x{00a0}~siu", " ", $str );

Try this:
尝试这个：
$str = str_replace("\u{00a0}", ' ', $str);

You have to do this with single quotes like this:
你必须用这样的单引号做到这一点：
str_replace('\u00a0', "",$string);
Or, if you like to use double quotes, you have to escape the backslash - which would look like this:
或者，如果您喜欢使用双引号，则必须转义反斜杠 - 如下所示：
str_replace("\u00a0", "",$string);
