htmlspecialchars（）：参数中的多字节序列无效

I am getting this error in my local site.

我在本地网站上收到此错误。

Warning (2): htmlspecialchars(): Invalid multibyte sequence in argument in [/var/www/html/cake/basics.php, line 207]

Does anyone knows, what is the problem or what should be the solution for this?

有谁知道,问题是什么或应该是什么解决方案?

Thanks.

Be sure to specify the encoding to UTF-8 if your files are encoded as such:

如果文件编码如下,请务必将编码指定为UTF-8:

htmlspecialchars($str, ENT_COMPAT, 'UTF-8');

The default charset for htmlspecialchars is ISO-8859-1 (as of PHP v5.4 the default charset was turned to 'UTF-8'), which might explain why things go haywire when it meets multibyte characters.

htmlspecialchars的默认字符集是ISO-8859-1(从PHP v5.4开始,默认字符集被转换为'UTF-8'),这可以解释为什么当它遇到多字节字符时会出现问题。

I ran in to this error on production and found this great post about it -

我在生产中遇到了这个错误,发现了这篇关于它的好文章 -

It appears to be a bug in PHP (for CentOS at least) that displays this error on when display errors is Off!

它似乎是PHP中的一个错误(至少对于CentOS),当显示错误关闭时显示此错误!

You are feeding corrupted character data into the function, or not specifying the right encoding.

您正在将损坏的字符数据提供给函数,或者不指定正确的编码。

I had this issue a while ago, old behavior (prior to PHP 5.2.7 I believe) was to return the string despite corruption, but since that version it will throw this error instead.

我刚才有这个问题,旧的行为(我相信PHP 5.2.7之前)是尽管腐败仍然返回字符串,但是从那个版本开始它会抛出这个错误。

My solution involved writing a script to feed my strings through iconv using the //IGNORE modifier to remove corrupted data.

我的解决方案包括使用// IGNORE修饰符编写脚本以通过iconv提供我的字符串以删除损坏的数据。

(We had a corrupted database which had some strings in UTF-8, some in latin-1 usually with incorrectly defined character types on the columns).

(我们有一个损坏的数据库,它有一些UTF-8中的字符串,一些在latin-1中,通常在列上有错误定义的字符类型)。

(Looking at the comment to Tatu's answer, I would start by looking at (and playing with) the contents of the $charset variable.

(看看对Tatu的回答的评论,我将从查看(和玩)$ charset变量的内容开始。

The correct code in order not to get any error is:

正确的代码,以便不会出现任何错误:

htmlentities($string, ENT_IGNORE, 'UTF-8') ;

htmlentities($ string,ENT_IGNORE,'UTF-8');

Beside this you can also use str_replace to replace some bad characters to your needs and then use htmlentities function.

除此之外,您还可以使用str_replace将一些不良字符替换为您的需要,然后使用htmlentities函数。

Have a look at this rss feed it replaced the greater html sign to gt; tag which might not look nice when reading thee rss feed. You can replace this with something like "-" sign or ")" and etc.

看看这个RSS源它取代了更大的html符号到GT;阅读the rss feed时看起来可能不太好的标签。您可以用“ - ”符号或“)”等替换它。

Had the same problem because I was using substr on utf-8 string.
Error was infrequent and seemingly random. Error occurred only if string was cut on multibyte char!

有同样的问题,因为我在utf-8字符串上使用substr。错误很少见,似乎是随机的。只有在多字节字符串上剪切字符串时才会出错!

mb_substr solved the problem :)

mb_substr解决了问题:)

That's actually one of the most frequent errors I get.

这实际上是我得到的最常见的错误之一。

Sometimes I dont use __() translation - just plain German text containing äöü. There it is especially important to mind the encoding of the files.

有时我不使用__()翻译 - 只是包含äöü的普通德语文本。在那里,特别重要的是要记住文件的编码。

So make sure you properly save the files that contain special chars as UTF8.

因此,请确保正确保存包含特殊字符的文件为UTF8。
