编码到Utf8，我有一些说明，

Question

几周前，我意识到我们网站上的一些旧列表上有一些奇怪的字符

我有一些这样的字符，它们相当于双引号(")我有一些字符，比如ƒ，？？

我想把它们修好，但我不知道怎么修。

因为当我使用preg_replace时，如果我编写以下代码

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

$test仍然会在字符串中包含该编码错误，因此就像preg_replace看不到编码问题一样。

有没有人知道我能做些什么来修复这些编码错误？或者有没有办法让我继续下去

谢谢

好的，我现在要做的是将每个字符转换回utf8，因为由于某些原因，我的字符串与一些编码混合在一起。

这是一个字符串和组成该字符串的字符的细目。

我现在能做什么？

Answer 1

查看github中流行编码的PHP Class Encoding

用法：

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

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

另外：

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

示例：

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：(我检查这个工作正常)

$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.

Answer 2

早些时候，我在从多种语言的xml提要中获取数据时也遇到过同样的问题。

经过一番努力，我找到了一个解决方案，那就是一切都用utf8编码。

1)数据库联合和字符集。

2)数据库连接。

3) html页面类型。
