Trying to get the euro symbol using chr(128)
提问by ziiweb
I expected this code:
我期望这个代码：
define('EURO_SIMBOLO', chr(128));
$euro = EURO_SIMBOLO;
var_dump($euro);
to show the symbol, but it doesn't. Why does this happen?
显示符号，但它没有。为什么会发生这种情况？

If you want to go with Unicode, UTF-8 more specifically, which I prefer because of its flexibility, you can output the Euro sign using:
如果您想使用 Unicode，更具体地说是 UTF-8，我更喜欢它的灵活性，您可以使用以下命令输出欧元符号：
echo "\xE2\x82\xAc"; // 3 bytes-long multibyte character

This will only work if you're using a 125x code page. The fact is that the euro character is not included in allextended ASCII character sets (introduced in ISO/IEC 8859-15), however it does have a de-facto Unicode character.
这仅在您使用125x 代码页时才有效。事实上，欧元字符并未包含在所有扩展 ASCII 字符集中（在 ISO/IEC 8859-15 中引入），但它确实具有事实上的 Unicode 字符。
If this is simply for displaying in a browser, consider using either '€'or '€'
如果这只是为了在浏览器中显示，请考虑使用'€'或'€'

Instead of (alt + 0128)
而不是 (alt + 0128)
switch your euro code to
将您的欧元代码切换为
€

If you are using such a character set with the euro-symbol you're most likely using iso-8859-15 in which the '' character is defined at position 164. So you might have more luck if you replace 128 by 164, although this won't help you in utf-8 environments in which the previous answer might be more suited.
如果您使用带有欧元符号的此类字符集，您很可能会使用 iso-8859-15，其中 '' 字符定义在位置 164。因此，如果将 128 替换为 164，您可能会更幸运，尽管在 utf-8 环境中，这对您没有帮助，而先前的答案可能更适合。

In the CP1252 encoding of has the code 128; In ISO-8859-15 the code is 164; Macintosh Roman is 219;
CP1252编码中的有编码128；在 ISO-8859-15 中，代码是 164；Macintosh Roman 是 219；
The euro sign is a part of the ASCII. Look that http://www.ascii-code.com/
欧元符号是 ASCII 的一部分。看那个http://www.ascii-code.com/
