编码为 Utf8，我有一些

【问题标题】：Encoding To Utf8, I have some ÂÂ编码为 Utf8，我有一些
【发布时间】：2013-09-11 15:06:00
【问题描述】：

几周前我意识到我们网站上的一些旧列表中有一些奇怪的字符

我有一些像这样的字符  等于双引号 (") 我有一些像â这样的角色？？

我想修复它们，但我不知道如何。

自从我使用 preg_replace 如果我制作此代码时

$text = 'this is a listingTitle  with an encoding problem';
$test = preg_replace("/ÂÂ/",'"',$text);
echo$test;

$test 仍然会在字符串中出现编码错误，所以就像 preg_replace 看不到编码问题一样。

有没有人知道我可以做些什么来修复这些编码错误？ 或者有什么方法我应该继续

谢谢

在此处编辑--------------------------------------------- -----

好的，我现在要做的是将每个字符转换回 utf8 而且由于某种原因，我的字符串混合了一些编码..

所以这里是一个字符串和构成该字符串的字符的细分。

我现在能做什么？

【问题讨论】：

  • 如果将字符串解码为 ISO 格式会发生什么？ php.net/manual/en/function.utf8-decode.php
  • 此$test = $preg_replace("/ÂÂ/",'"',$text); 不应在preg_replace 前面有$。现在尝试使用$test = preg_replace("/ÂÂ/",'"',$text); 并在echo$test; 中放置一个空格@ 没什么大不了的，但它确实将您的回声与您的变量echo $test; 分开了
  • $text = '这是一个listingTitle，有编码问题'; $test = utf8_decode($text);现在我明白了，这是一个有编码问题的列表标题
  • @NicolasRacine 然后你需要一个不同类型的函数并检查不在标准字符集中的字符。
  • @Fred -ii- 好的，所以我应该做的是检查每个字符，如果一个字符不在正确的字符集中，我会更改它吗？抱歉，我不太清楚你的意思

【解决方案1】：

在github中查看这个 PHP 类编码，其中包含流行的编码

用法：

$utf8_string = Encoding::toUTF8($utf8_or_latin1_or_mixed_string);

$latin1_string = Encoding::toLatin1($utf8_or_latin1_or_mixed_string);

还有：

$utf8_string = Encoding::fixUTF8($garbled_utf8_string);

例子：

echo Encoding::fixUTF8("Fédération Camerounaise de Football");
echo Encoding::fixUTF8("FÃédÃération Camerounaise de Football");
echo Encoding::fixUTF8("FÃÃédÃÃération Camerounaise de Football");
echo Encoding::fixUTF8("FÃÃÃédÃÃÃération Camerounaise de Football");

将输出：

Fédération Camerounaise de Football
Fédération Camerounaise de Football
Fédération Camerounaise de Football
Fédération Camerounaise de Football

更新：

检查这个：（我检查了这个工作）

$output = 'this is a listingTitle  with an encoding problem';
$output = preg_replace('/[^(\x20-\x7F)]*/','', $output);
echo($output);

输出：

this is a listingTitle with an encoding problem.

【讨论】：

  • Hum Html 净化器很酷！但它并没有消除编码错误。 :(
  • 1- u SET NAMES utf8 在插入数据之前？ 2- 检查PhpMyadmin 并告诉我你的字符集是什么？ 3- AddDefaultCharset UTF-8 在 Apache 配置中。
  • 现在我做了，（设置 UTF-8）但这不是问题，数据已经在数据库中，现在一切正常。但旧清单有这种错误。我的字符集是 utf-8_general_ci
  • 它和 :S 输出的字符串一样吗？而不是
  • 你救了我的命！
【解决方案2】：

之前我在从多种语言的xml 提要中获取数据时也遇到了同样的问题。

经过努力，我找到了一个解决方案，方法是使用utf8 编码创建所有内容。

1) 数据库联盟和字符集。

2) 数据库连接。

3) html 页面类型。

【讨论】：

  • 这是我一开始做的。但看起来这些错误在它自己的数据库中。
  • 是的，它不适用于数据库中已保存的内容。为此，您必须更新它们。但从现在开始，新的记录就可以了。
  • 是的，我知道，:) 但问题是我现在需要尝试修复那些在 :S 上有一些错误的旧列表
  • 不是 100% 确定，但在这种情况下，您必须先找到它们的实际编码，然后再翻译成它们的实际语言。
