php with special characters like ?
提问by Fred
At first I thought the problem was when I return echo json_encode($row) from an ajax call that results with ? are changed to NULL. But after testing I found out that the problem exists way before that.
起初我认为问题是当我从结果为 ? 更改为 NULL。但是经过测试，我发现问题在那之前就存在了。
In a sample php file with:
在一个示例 php 文件中：
$test = "Nu?ez"
echo $test
the result is just Nu?ez
结果只是 Nu?ez
I've searched around but none of the suggested solutions work. Like:
我四处搜索，但没有一个建议的解决方案有效。喜欢：
mb_internal_encoding('UTF-8');
mb_http_output('UTF-8');
mb_http_input('UTF-8');
mb_language('uni');
mb_regex_encoding('UTF-8');
ob_start('mb_output_handler');
or <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />, or header('content-type: text/html; charset: utf-8');. And some more solutions that I've already forgotten, believe me I tried a lot.
或<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />, 或header('content-type: text/html; charset: utf-8');。还有一些我已经忘记的解决方案，相信我，我尝试了很多。
That's just the beginning of it, I'm hoping that won't be a problem with mysql since my database is in utf-8 so is my $mysqli charset. But I think I can't say the same for ajax json_encode. But nevermind, one problem at a time. Can anybody please help me. Thanks a lot!
这只是它的开始，我希望 mysql 不会有问题，因为我的数据库是 utf-8，所以我的 $mysqli 字符集也是如此。但我想我不能对 ajax json_encode 说同样的话。但没关系，一次一个问题。任何人都可以帮助我。非常感谢！
PROBLEM SOLVEDI just had to set "Encode in UTF-8" in Notepad++, as it was in "Encode in ANSI" before.
问题已解决我只需要在 Notepad++ 中设置“以 UTF-8 编码”，就像之前在“以 ANSI 编码”中一样。

to show correctly latin characters like ? ? á é í ó ú, etc.. in browsers, you have to use iso-8859-1 instead of UTF-8 encoding http://www.w3schools.com/tags/ref_entities.asp
正确显示拉丁字符，如？? á é í ó ú 等。在浏览器中，您必须使用 iso-8859-1 而不是 UTF-8 编码 http://www.w3schools.com/tags/ref_entities.asp
best regards!
此致！

when you connect to your mysql db, set charset to utf-8, like ->
当您连接到 mysql 数据库时，将字符集设置为 utf-8，例如 ->
$sql_con = mysql_connect($sql_host, $sql_user, $sql_pass);
mysql_query('SET NAMES utf8');

consider setting default_charset, this worked for me
考虑设置 default_charset，这对我有用
ini_set('default_charset', 'utf-8');
ini_set('default_charset', 'utf-8');

Face the same issue with the string "CASTA?O".
字符串“CASTA?O”也面临同样的问题。
I've tried posted solutions.
我试过发布的解决方案。
I used the ini_set('default_charset', 'utf-8');directive.
我使用了ini_set('default_charset', 'utf-8');指令。
- The selected record showed "CASTA?O"
- Using utf8-decodeshowed "CASTA?O"
- Using utf8_encodeshows the proper string "CASTA?O"
- 所选记录显示“CASTA?O”
- 使用utf8-decode显示 "CASTA?O"
- 使用utf8_encode显示正确的字符串“CASTA?O”
