由于我的应用程序中存在编码问题，我需要用常规引号（'和“）替换单引号和双引号（“ ” ‘ ’）的Microsoft Word版本。我不需要它们是HTML实体和我无法更改我的数据库架构。
我有两个选择：使用正则表达式或关联数组。
有更好的方法吗？

我找到了这个问题的答案。在php中使用iconv()函数只需要一行代码：
// replace Microsoft Word version of single and double quotations marks (“ ” ‘ ’) with regular quotes (' and ")
$output = iconv('UTF-8', 'ASCII//TRANSLIT', $input);

考虑到你只想要替换一些特定且识别良好的角色，我会选择str_replace一个数组：你显然不需要重型大炮将会带给你; - ）
如果你遇到其他一些特殊字符（该死的复制粘贴来自word ...），你可以随时将它们添加到该数组中/只要它们被识别出来。
编辑：我可以给你的评论的最佳答案可能是这个链接：Convert Smart Quotes with PHP
相关代码（引用该页面）：
function convert_smart_quotes($string)
{
$search = array(chr(145),
chr(146),
chr(147),
chr(148),
chr(151));
$replace = array("'",
"'",
'"',
'"',
'-');
return str_replace($search, $replace, $string);
}
（我这台电脑上没有MS字，所以我不能自己测试）
我不记得我们在工作中使用的确切（我不是那个必须处理那种输入的人），但它是同样的东西...

您的 Microsoft编码的引号可能是typographic quotation marks。如果您知道要替换它们的字符串编码，则可以使用str_replace替换它们。
以下是UTF-8的示例，但使用带strtr的单个映射数组：
$quotes = array(
"\xC2\xAB" => '"', // « (U+00AB) in UTF-8
"\xC2\xBB" => '"', // » (U+00BB) in UTF-8
"\xE2\x80\x98" => "'", // ‘ (U+2018) in UTF-8
"\xE2\x80\x99" => "'", // ’ (U+2019) in UTF-8
"\xE2\x80\x9A" => "'", // ‚ (U+201A) in UTF-8
"\xE2\x80\x9B" => "'", // ‛ (U+201B) in UTF-8
"\xE2\x80\x9C" => '"', // “ (U+201C) in UTF-8
"\xE2\x80\x9D" => '"', // ” (U+201D) in UTF-8
"\xE2\x80\x9E" => '"', // „ (U+201E) in UTF-8
"\xE2\x80\x9F" => '"', // ‟ (U+201F) in UTF-8
"\xE2\x80\xB9" => "'", // ‹ (U+2039) in UTF-8
"\xE2\x80\xBA" => "'", // › (U+203A) in UTF-8
);
$str = strtr($str, $quotes);
如果您需要其他编码，可以使用mb_convert_encoding转换密钥。

如果像我一样，你带着大量破碎的ascii / ms单词字符到达这里，这些字符正在为你的CMS或RTE做出奇怪的事情而且iconv无效，那么这个疯狂的功能可能只适合你。
将此功能保存到文件时，请确保您的编码为utf-8。

答案 4 :(得分：5)
我们使用以下内容。处理一些特殊字符。
$text = str_replace(chr(130), ',', $text); // baseline single quote
$text = str_replace(chr(132), '"', $text); // baseline double quote
$text = str_replace(chr(133), '...', $text); // ellipsis
$text = str_replace(chr(145), "'", $text); // left single quote
$text = str_replace(chr(146), "'", $text); // right single quote
$text = str_replace(chr(147), '"', $text); // left double quote
$text = str_replace(chr(148), '"', $text); // right double quote
$text = mb_convert_encoding($text, 'HTML-ENTITIES', 'UTF-8');

除了@ Gumbo之外，之前的每一个答案都会破坏Unicode字符串：
echo convert_smart_quotes("This is Yi: ꑑ. Point ⒒ this breaks Yi. Yi broke–why? I need a longer––point. This makes Han 嗗 mad.");
结果：
This is Yi: ?''. Point ?'' this breaks Yi. Yi broke?"why? I need a longer?"?"point. This makes Han ?-- mad.
iconv：
$output = iconv('UTF-8', 'ASCII//TRANSLIT', $input);
结果：
PHP Notice: iconv(): Detected an illegal character in input string in php shell code on line 1
您可以将其更改为//IGNORE，这将删除字符，但不会翻译它们。
这是替换CP1252中编码的Microsoft引号的最佳方法。如果它们是Unicode并且您需要替换它们，请使用Gumbo的答案：
