问题
When i see data as stored on mysql database using phpmyadmin, the characters are stored exactly as é à ç however when i use php to display these data on an html document that has the exact following structure:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>
</head>
<body>
</body>
</html>
I got square instead of accented character, however, i don't have this issue with any accented characters on static content that haven't been loaded from mysql in the same page.
when i see on the source code of the page they seem to be identical! for example:
part of static data on the source code displayed as:
éçà
part of mysql origin data:
éçà
i tried replacing
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
with
<meta http-equiv="Content-Type" content="text/html; charset=windows-1552" />
and as result i got mysql one fixed, static with squares !
any hints?
回答1:
This is quite common charset issue, you need to set connection encoding manually for MySQL connection (those should be first queries you execute after establishing connection):
SET NAMES utf8;
SET CHARACTER SET utf8;
And also make sure every table has CHARACTER SET set to UTF-8.
Or you could also update server configuration.

Looks like a misconfiguration issue. Most probably your DB or drivers are not using UTF-8.
The fact that the data that comes from the DB shows OK when you change to windows-1552 and the static files do not can mean that your source file is (correctly) in UTF-8, but the data from your DB is arriving in the wrong encoding format.
Whatever is going on, stick to UTF-8.
UPDATE: There is a thread that explains how to automatically set the encoding for the connection:
Change MySQL default character set to UTF-8 in my.cnf?
