i have a proble, when insert something in foreign language into database.
i have set the collation of database to utf8_general_ci(try utf8_unicod_ci too).
but when i insert some text into table, it was saved like this
Õ€Õ¡ÕµÕ¥Ö€Õ¥Õ¶ Ô±Õ¶Õ¸Ö‚Õ¶
but when i read from database, text shows in correct form. it looks like that only in database.
i have set encoding in my html document to charset=UTF-8
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
and i set
mysql_query("SET NAMES UTF-8");
mysql_query("SET CHARACTER SET UTF-8");
when conecting to database.
so i think that i' ve done everything, but it still save in that anknown format.
could you help me.
thanks in advance
I believe you have to SET NAMES utf8, instead of UTF-8, in MySQL.
It looks like maybe your phpmyadmin isn't using the correct charset. In your phpmyadmin folder, open config.default.php and edit the lines
$cfg['DefaultCharset'] = 'iso-8859-1';
$cfg['DefaultLang'] = 'en-iso-8859-1';
To your chosen encoding.
It is suggested to use mysql_set_charset() instead of "SET NAMES" query, however the impact should be the same.

I included this at the top of my php file:
<?php
header('Content-Type: text/html; charset=UTF-8');
?>
I did this because my file.php was not displaying "á, é, í, ó, ú or ¿" in the html file or from data queried from my database.
After I placed the 'header('Content-Type: text/html; charset=UTF-8');' line of code my html page started to understand the special characters in the html file but, data received from my database now has a black rhombus with a question mark.
The collation my database has is "utf8_spanish_ci"
at the html tag i tried to put lang=es but this never worked I also tried to put the meta tag inside the head tag
<!DOCTYPE html>
<html lang=es>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<head>
I also tried:
<meta charset="utf-8">
and:
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
I don't know what the problem is. When I insert data directly into the data base the special characters are there but when I insert them from my file.php they appear with random characters.
Does anyone know why this is happening?
There are a couple of reasons this could be happening. It is however important that your entire line of code uses the same set of charset, and that all functions that can be set to a specific charset, is set to the same. The most widely used one is UTF-8, which is the one I'm suggesting you use.
Connection
You also need to specify the charset in the connection itself.
PDO (specified in the object itself):
$handler = new PDO('mysql:host=localhost;dbname=database;charset=utf8', 'username', 'password', array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET CHARACTER SET UTF8"));
MySQLi: (placed directly after creating the connection)
* For OOP: $mysqli->set_charset("utf8");
* For procedural: mysqli_set_charset($mysqli, "utf8");
(where $mysqli is the MySQLi connection)
MySQL (depricated, you should convert to PDO or MySQLi): (placed directly after creating the connection)
mysql_set_charset("utf8");
Database
Your database and all its tables has to be set to UTF-8. Note that charset is not the same as collation.
You can do that by running the queries below once for each database and tables (for example in phpMyAdmin)
ALTER DATABASE databasename CHARACTER SET utf8 COLLATE utf8_unicode_ci;
ALTER TABLE tablename CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci;
File-encoding
It's also important that the .php file itself is UTF-8 encoded. If you're using Notepad++ to write your code, this can be done in the "Format" drop-down on the taskbar (Convert to UFT-8 w/o BOM). You should use UTF-8 w/o BOM.
Should you follow all of the pointers above, chances are your problem will be solved. If not, you can take a look at this StackOverflow post: UTF-8 all the way through.
Are you sure? And are you sure that you are retrieving your data from the data base? Having said that, most databases require you to save data in a way that is NOT exactly like your question. There is really valid security reasons for this.
You should use utf8_general_ci as a database encoding also before insert query you should run this query
Mysql_query(" SET NAMES 'utf8'");
I've got a mysql table with some imported data, in particular one value is Sinn Féin.
The character set used for my database is utf8_general_ci. The data displays fine in phpMyAdmin. In my site, I've used the PHP header header("Content-type: text/html; charset='utf-8'");. I've got <meta http-equiv="Content-type" content="text/html; charset=utf-8" /> in my <head>.
My data still comes up as Sinn F�in. I've tried using utf8_decode, but that doesn't help. What am I doing wrong?
Аfter mysql_connect() add this line:
mysql_query ("SET NAMES utf8");
Try this:
$dbc="database connection";
mysql_query("SET NAMES utf8",$dbc);
I'm trying to save French accents in my database, but they aren't saved like they should in the DB.For example, a "é" is saved as "é".I've tried to set my files to "Unicode (utf-8)", the fields in the DB are "utf8_general_ci" as well as the DB itself.When I look at my data posted through AJAX with Firebug, I see the accent passed as "é", so it's correct.Thanks and let me know you need more info!
Personally I solved the same issue by adding after the MySQL connection code:
mysql_set_charset("utf8");
or for mysqli:
mysqli_set_charset($conn, "utf8");
or the mysqli OOP equivalent:
$conn->set_charset("utf8");
And sometimes you'll have to define the main php charset by adding this code:
mb_internal_encoding('UTF-8');
On the client HTML side you have to add the following header data :
<meta http-equiv="Content-type" content="text/html;charset=utf-8" />
In order to use JSON AJAX results (e.g. by using jQuery), you should define the header by adding :
header("Content-type: application/json;charset=utf8");
json_encode(
some_data
);
This should do the trick
The best bet is that your database connection is not UTF-8 encoded - it is usually ISO-8859-1 by default.
Try sending a query
SET NAMES utf8;
after making the connection.
mysqli_set_charset($conn, "utf8");
if you use PDO, you must instanciate like that :
new \PDO("mysql:host=$host;dbname=$schema", $username, $password, array(\PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8') );
Use UTF8:
Set a meta in your
<meta http-equiv="Content-type" content="text/html;charset=utf-8" />
When you connect to your mySQL DB, force encoding so you DONT have to play with your mysql settings
$conn = mysql_connect('server', 'user', 'password') or die('Could not connect to mysql server.');
mysql_select_db('mydb') or die('Could not select database.');
mysql_set_charset('utf8',$conn); //THIS IS THE IMPORTANT PART
If you use AJAX, set you encoding like this:
header('Content-type: text/html; charset=utf-8');
Have you reviewed http://dev.mysql.com/doc/refman/5.0/en/charset-unicode.html:
Client applications that need to
communicate with the server using
Unicode should set the client
character set accordingly; for
example, by issuing a SET NAMES 'utf8'
statement. ucs2 cannot be used as a
client character set, which means that
it does not work for SET NAMES or SET
CHARACTER SET. (See Section 9.1.4,
“Connection Character Sets and
Collations”.)
Further to that:
if you get data via php from your
mysql-db (everything utf-8) but still
get '?' for some special characters in
your browser (), try this:
after mysql_connect() , and
mysql_select_db() add this lines:
mysql_query("SET NAMES utf8");
worked for me. i tried first with the
utf8_encode, but this only worked for
äüöéè... and so on, but not for
kyrillic and other chars.
You need to a) make sure your tables are using a character encoding that can encode such characters (UTF-8 tends to be the go-to encoding these days) and b) make sure that your form submissions are being sent to the database in the same character encoding. You do this by saving your HTML/PHP/whatever files as UTF-8, and by including a meta tag in the head that tells the browser to use UTF-8 encoding.
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
Oh, and don't forget C, when connecting to the database, make sure you're actually using the correct character set by executing a SET NAMES charset=utf8 (might not be the correct syntax, I'll have to look up what it should be, but it will be along those lines)
PHP(.net) advises against setting charsets after connecting using a query like SET NAMES utf8 because your functionality for escaping data inside MySQL statements might not work as intended.
Do not use SET NAMES utf8 but use the appropriate ..._set_charset() function (or method) instead, in case you are using PHP.
Ok I have found a working solution for me :
Run this mysql command
show variables like 'char%';
Here you have many variables : "character_set_server", "character_set_system" etc.
In my case I have "é" for "é" in database and I want to show "é" on my website.
To work I have to change "character_set_server" value from "utf8mb4" to "latin1".
All my correct value are :
And other values are :
With theses values the wrong database accent are corrected and well displayed by the server.
But each case can be different.
I have a MySQL database with the following settings:
MySQL charset: UTF-8 Unicode (utf8)
MySQL connection collation: utf8_unicode_ci
I have a table with a column named "softtitle", this column is coded in utf8_general_ci. The entries of this column contain Chinese characters. If I run SQL through the PHPMyAdmin Control pane, the Chinese characters are shown correctly. But if I run SQL through a PHP file, all Chinese characters are shown wrongly. Here is the PHP file:
<?php
header("Content-Type: text/html; charset=utf8_general_ci");
mysql_connect("116.123.163.73","xxdd_f1","xxdd123"); // host, username, password
mysql_select_db("xxdd");
mysql_query("SET names 'utf8_general_ci'");
$q = mysql_query("SELECT softtitle
FROM dede_ext
LIMIT 0 , 30");
while($e = mysql_fetch_assoc($q))
$output[] = $e;
print(json_encode($output));
mysql_close();
?>
What is wrong here? What should I do to fix this problem? Thank you very much!
You header is wrong. You're not supposed to set it to the character set of the table/database.
header("Content-Type: text/html; charset=UTF-8");
The same applies for "SET NAMES":
mysql_query("SET names 'utf8'");
And as a last thing, you are printing out json encoded data, your Content-type shouldn't be text/html but application/json.
because this Q&A still ranks highly in Google search results..
setting aside for a moment the general advice to switch from using mysql statements in php to using mysqli, replace this:
mysql_connect("116.123.163.73","xxdd_f1","xxdd123");
mysql_select_db("xxdd");
with this:
$con = mysql_connect("116.123.163.73","xxdd_f1","xxdd123");
mysql_set_charset($con, 'utf8');
mysql_select_db("xxdd");
check that your database, or at least the column, really IS collated as utf8_general_ci - though you might get better results with utf8mb4_unicode_ci
if your php is producing a purely JSON output, for example, a JSON 'object' that you're picking up with an AJAX call to pull data into another document, the header you should use in the PHP file is
header("Content-Type: application/json", true);
and not a header content-type of text/html or anything else.
and finally, assuming you're eventually presenting the values taken from the DB and placed into your JSON onto an html document, remember the to start that document with the following:
<!DOCTYPE html>
<html lang="zh-Hans">
<head>
<meta charset="utf-8">
...etc
note the declaration of utf-8 in the meta of the head, and the declaration of the language (chinese simplified in my code above = zh-Hans). If you are using a script which is written from right to left, eg. arabic sccripts, add dir="rtl" into the tag as well.
My website uses:
<!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">
And this meta:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
I created my database and tables in phpMyAdmin making sure everything is set as utf8_unicode_ci (table, fields, database), even the connection collation.
When I insert some latin characters (accents, ñ and stuff like that) into the database using an standard form made in PHP, it works fine, I can display the saved data in my website no problem. But if I go to phpMyAdmin, all the latin characters are all messed up, something like ñññ.
If I try to fix that data in phpMyAdmin, then my website displays the data incorrectly, with weird symbols ���.
What in this world am I doing wrong? I've been trying to work this out for hours with no success.
Thank you all!
As #Artefacto says, this could be a problem local to phpMyAdmin.
If phpMyAdmin is fine (i.e. set to UTF-8) and the data is still showing up weird, then look at whether your database connection using UTF-8 as well?
mysql_query("SET NAMES utf8")
(or whatever you use as a database library)
might help if it isn't.
If phpMyAdmin is showing ñññ instead of ñññ, that's because it's interpreting a UTF-8 bytestream as ISO-8859-1. So your database contents are probably correct, phpMyAdmin is just showing them in a wrong manner.
I'm not familiar with the application, but you can force the browser to read the page as UTF-8 (typically View > Encoding > UTF-8).
for Scuzzu's Question there are several ways:
http://www.mysqlperformanceblog.com/2007/12/18/fixing-column-encoding-mess-in-mysql/
I would have eight more links with different tasks but this site is prevent me from saving them...
"as a spam prevention mechanism, new users can only post a maximum of one hyperlink"
mysql_query("SET NAMES utf8") solved my problem.
Problem: Characters displayed correctly in phpMyAdmin, wrong in HTML/PHP. Characters: â, î, etc.
The headers are ok (utf8), phpmyadmin displays the content in the correct form, but the website keeps showing weird question-mark characters (inside a black diamond character).
HTML code:
<!DOCTYPE html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
Solution: I've added in php (preceding any other queries):
mysql_query("SET NAMES utf8");
Other causes can lead to this behaviour; this is only one part of the solution. You may need to check content-type, web server configuration (httpd.conf), html lang / dir, charset, etc. However, question mark in a black diamond seems to be more specific to this problem/solution, in other cases are displayed 2-3 weird characters instead of the one you want.
After doing mysql_query("SET names 'utf8';");
You need also to go to mySQL and define collation as UTF-8, also!
This should solve your problem.
Good luck!
1- Edit file:
my.ini (MsWindos)
my.cnf (GNU/linux)
2- Look for [mysqld] entry and append:
character-set-server = utf8
skip-character-set-client-handshake
The whole view should look like:
[mysqld]
port=3306
character-set-server = utf8
skip-character-set-client-handshake
3- Restart MySQL service!
If phpMyAdmin is fine (i.e. set to UTF-8) and the data is still showing up weird, then look at whether your database connection using UTF-8 as well?
Just set mysql_query("SET NAMES utf8"); after mysql_connect line:
$con = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD) or die(mysql_error());
mysql_query("SET NAMES utf8");
I was struggled with the same problem and finally found an elegant way to check and change collation via PHP function mysqli_set_charset. Following piece of code has to be included between a $conn check and an $sql query:
if (!mysqli_set_charset($conn, "utf8")) {
printf("Error loading character set utf8: %s\n", mysqli_error($conn)); //optional row
die();
}
I found the solution here: http://php.net/manual/en/mysqli.set-charset.php
