php - 编码为 Utf8，我有一些

Question

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 的字符？？

我想修复它们，但我不知道如何。

自从我使用 preg_replace 后，如果我编写这段代码

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

$test 仍然会在字符串中出现编码错误，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

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

所以这是一个字符串和构成该字符串的字符的分割。

我现在可以做什么？

Answer 1

检查此 PHP 类编码，在 github 中采用流行的编码

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:(我检查了这个有效)

$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.
