問題描述

是否有將 UTF-8 轉換為 Unicode 而將非特殊字符保留為普通字母和數字的函數?

Is there a function that will change UTF-8 to Unicode leaving non special characters as normal letters and numbers?

即德語單詞tchü?"將被呈現為類似于tch20AC21AC"(請注意我正在制作 Unicode 代碼).

ie the German word "tchü?" would be rendered as something like "tch20AC21AC" (please note that I am making the Unicode codes up).

我正在試驗以下函數，但盡管這個函數適用于 ASCII 32-127，但對于雙字節字符似乎失敗了:

I am experimenting with the following function, but although this one works well with ASCII 32-127, it seems to fail for double byte chars:

function strToHex ($string)
{
    $hex = '';
    for ($i = 0; $i < mb_strlen ($string, "utf-8"); $i++)
    {
        $id = ord (mb_substr ($string, $i, 1, "utf-8"));
        $hex .= ($id <= 128) ? mb_substr ($string, $i, 1, "utf-8") : "&#" . $id . ";";
}

    return ($hex);
}

有什么想法嗎?

編輯 2:找到解決方案:PHP ord() 函數不適用于雙字節字符.改用:http://nl.php.net/manual/en/function.ord.php#78032

EDIT 2: Found solution: The PHP ord() function does not work for double byte chars. Use instead: http://nl.php.net/manual/en/function.ord.php#78032

推薦答案

可以使用 iconv 將一種字符集轉換為另一種字符集:

Converting one character set to another can be done with iconv:

請注意，UTF 已經是 Unicode 編碼了.

Note that UTF is already an Unicode encoding.

另一種方法是簡單地使用具有正確字符集的 htmlentities:

Another way is simply using htmlentities with the right character set:
