如何将特殊字符转换为普通字符？

Question

我正在尝试转换字符，例如：

ë, ä, ï, ö, etc.

对于普通角色，例如：

e, a, i, o, etc.

做到这一点的最佳方法是什么？ 我尝试过很多东西，比如 preg_replace 和 str_replace。

有人可以帮我吗？

我尝试的是：

$ts = array("[À-Å]","Æ","Ç","[È-Ë]","/[Ì-Ï]/","/Ð/","/Ñ/","/[Ò-ÖØ]/","/×/","/[Ù-Ü]/","/[Ý-ß]/","/[à-å]/","/æ/","/ç/","/[è-ë]/","/[ì-ï]/","/ð/","/ñ/","/[ò-öø]/","/÷/","/[ù-ü]/","/[ý-ÿ]/");

$tn = array("A","AE","C","E","I","D","N","O","X","U","Y","a","ae","c","e","i","d","n","o","x","u","y");

$title = preg_replace($ts, $tn, $text);

Answer 1

试试这个..对我有用。

iconv('utf-8', 'ascii//TRANSLIT', $text);

Answer 2

我喜欢stevies的答案，但为了完整起见，这对我有用。

preg_replace("/&([a-z])[a-z]+;/i", "$1", htmlentities($foo));

Answer 3

例如，从内容标题创建一个简单可读的 URL：

function cleanurl($title) {
        return urlencode(strtolower(str_replace(" ","-",preg_replace("/&([a-z])[a-z]+;/i", "$1", htmlentities($title)))));
}

Answer 4

我检查了每个解决方案，但没有一个对我有用。幸运的是我在 Prestashop 的代码中找到了它。这看起来有点矫枉过正，但如果有人想 100% 确定它会起作用，请尝试一下。
