$dblocation = "localhost";
$dbname = "xx";
$dbuser = "xx";
$dbpasswd = "xx";
$dbcnx = #mysql_connect($dblocation,$dbuser,$dbpasswd);
mysql_select_db($dbname, $dbcnx);
mysql_query("SET NAMES utf8");
mysql_query("SET COLLATION_CONNECTION=utf8_bin");
$name = mysql_real_escape_string($name);
$about = mysql_real_escape_string($about);
mysql_query("INSERT INTO votes
(name, about, active) VALUES('".$name."', '".$about."', 1 ) ")
or die(mysql_error());
It works perfectly fine when $name and $about is not cyrillic. But when it's cyrillic - script just adds a row with blank name and about fields. What do?
DB is UTF-8, manual adding rows with phpMyAdmin with cyrillic symbols works perfect, PHP-script is UTF-8, everything's UTF-8.
You should have:
1.header ("Content-Type: text/html; charset=utf-8"); or <meta http-equiv="content-type" content="text/html; charset=utf-8" />
2.mysql_query("SET NAMES 'utf8'");
3.Set your file's encoding to utf-8 without BOM
Specify character set which should be used by the connection with mysql_set_charset(...'). See http://php.net/manual/en/function.mysql-set-charset.php.
I've dealt a lot with the cyrillic and it is tricky indeed. So far in my experience I did not use any COLLATION_CONNECTION. All I do is put, as you did, all possible files in utf8. Then the fields in the DB I put in "utf8_unicode_ci" and I only use the SET NAMES params to set the connection encoding. This should be enough. Mind that the Set names might be tricky, as only a single space in extra and it will not work. I use:
define("DBENCODING", "utf8");
mysql_query("SET NAMES '".DBENCODING."'", $this->connection);
I hope I managed to help.

I have a problem, when I try to echo a cyrillic character, it return like ????
Here's code
<?
include('db.php');
$sql = "SELECT * FROM menu_items WHERE reference=1";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
$rows = array();
while($row = $result->fetch_object()) {
$rows[] = json_encode($row);
}
$items = implode(',',$rows);
echo '['.$items.']';
}else {
echo "ERROR";
}
?>
Any idea?
Collation : utf8_general_ci
And db.php:
<?
$servername = "localhost";
$username = "test";
$password = "Conqwe333!";
$conn=mysqli_connect($servername,$username,$password,"test");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
?>
Worked after <? $conn->set_charset("utf8");?>
Add before your $sql
$conn->query('SET NAMES utf8');
You can read more about it here
Also you will need to set proper header for browser. You can do it by serveral ways for example in meta html tag or using header('Content-Type: text/html; charset=utf-8');
You should set collation per connection:
mysqli_set_charset
Also you can perform sql
SET NAMES utf8;
but it's not recommended
<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "test");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
/* change character set to utf8 */
if (!$mysqli->set_charset("utf8")) {
printf("Error loading character set utf8: %s\n", $mysqli->error);
} else {
printf("Current character set: %s\n", $mysqli->character_set_name());
}
$mysqli->close();
I am assuming you are using Bulgarian and UTF8, same will work for Russian and other languages, just change "bg" to proper string.
I do not recommend you to use cp1251, because it breaks unexpectedly with apache mod_rewrite and other tools like this.
You need to do following checks:
Check if your database / table collation is some UTF8. It could be utf8_general_ci or Bulgarian - difference is minimal and is more sorting related. (utf8_general_ci is perfectly OK)
Check you have following statement executed right after connect - set names UTF8;. You can do $mysqli->query("set names utf8");
Make sure you have proper "tags". Here an example:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html lang='bg' xml:lang='bg' xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Нов сайт :)</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf8">
You can include UTF8 "BOM" on the html, but it works pretty well without it. I usually work without "BOM", and when I want to be 100% complaint, I create an include file bom.php that contain just the BOM symbol and include it prior HTML template in normal PHP way, e.g. include "bom.php".
Hope this helps, if not, please comment.
EDIT:
Someone suggested you must be sure if your data is properly stored in MySQL. Easiest way is to open PHP MySQL Admin. If Cyrillic is shown there, all is OK.
I think the issue is a step back, try to first encode the cyrillic characters correctly: How to encode cyrillic in mysql?
i have the mysql connection below:
$dbLink = mysql_connect('127.0.0.1', 'root', '');
mysql_set_charset('utf8', $dbLink);
mysql_select_db('test', $dbLink);
mysql_set_charset('utf-8');
it was working fine 1 week ago, but suddenly it is not showing the utf-8 or arabic or unicode contents which are stored in the database. but now even in the database the characters has been changed like سید اØمد Ø´Ûید Ú©ÛŒ صØÛŒØ and showing in the php the same. before everything was perfect. and the content was showing properly.
even now when i make a new entry in the database its showing fine but something went wrong with the old entries any help please.......
i have tried set names, mysql_set_charset & <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> but nothing happened. please help otherwise my site will be hanged up......
Use MYSQLi because MYSQL is now deprecated.
To set charset utf-8 use mysqli_set_charset() like this:
$dbLink = mysqli_connect('127.0.0.1', 'root', '');
mysqli_set_charset($dbLink , 'utf8');
mysqli_select_db($dbLink, 'test');
If for any reason it is still displaying wrong characters, add this to the beginning of your documents:
// Tell PHP that we're using UTF-8 strings until the end of the script
mb_internal_encoding('UTF-8');
// Tell PHP that we'll be outputting UTF-8 to the browser
mb_http_output('UTF-8');
UPDATE
Select some contents from your database and output the value using iconv() and see if it shows the wright charset:
<?php
$dbLink = mysqli_connect('127.0.0.1', 'root', '');
mysqli_set_charset($dbLink , 'utf8');
mysqli_select_db($dbLink, 'test');
function get_table_contents(){
global $dbLink;
$contents = array();
$query = "SELECT * FROM ||YOUR TABLE HERE||";
$result = mysqli_query($connection, $query);
while($content = mysqli_fetch_assoc($result)){
$contents[] = $content;
}
return $contents;
}
$data = get_table_contents();
?>
<html>
<head></head>
<body>
<?php echo iconv(mb_detect_encoding($data[0]['||YOUR COLUMN||'], "UTF-8,ISO-8859-1"), "UTF-8", $data[0]['||YOUR COLUMN||']); ?>
</body>
</html>
I have a problem with polish characters. I can't get correctly written words, like '?ukasz' instead of "Łukasz" or even "null", when it supposed to be "Kraków". I tried "mysql_set_charset('utf-8'/'iso-8859-1')" after mysql_connect or iconv(on json_encode($output)) and it's still the same (except now there is "Krak\u00f3" instead of "null"). I'll appreciate any help.
This is a php file for my Android app:
$id_client = $_REQUEST['id_klienta'];
$con=mysql_connect('localhost', 'root', '') or die(mysql_error());
mysql_select_db('courier_helper') or die(mysql_error());
$sql=mysql_query("SELECT * FROM `clients` WHERE id_klienta='$id_client'");
while($r=mysql_fetch_assoc($sql))
$output[]=$r;
print(json_encode($output));
mysql_close($con);
?>
You have to make sure, that you are using UTF-8 everywhere:
script file encoding (UTF-8 instead of ANSI) - you can set encoding it in Notepad++
html code (meta charset)
database table charset (when you are creating table or database)
database mysql_set_charset('utf8', $connection_obj);
database SET NAMES utf8 - run that SQL command after connecting
And one more thing - get familiar with PDO. This is my PDO connect function I use:
function DbConnect()
{
$db_host = "localhost";
$db_name = "database_name";
$db_user = "your_username";
$db_pass = "your_passwd";
$link = new PDO("mysql:host=$db_host;dbname=$db_name; charset=UTF-8", $db_user, $db_pass);
$link->exec("set names utf8;");
return $link;
}
You can use that function like this (this is PDO example):
$link = DbConnect();
$query = $link->prepare("SELECT id FROM wp_users");
$query->execute();
$result = $query->fetchAll(PDO::FETCH_ASSOC);
You should have your database storing data as UTF8, which means converting your existing tables.
ALTER TABLE tablename CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
You also need to make sure your connection to the database is UTF8. You can make sure of that by running a SET NAMES query right after your connect.
SET NAMES UTF8
As others mentioned, you should start using PDO.
Hello I have this problem: I have MySQL Database with collation latin1_bin. In database I have table with collation utf8_slovak_ci. All collumns is text. In rows I have values with ť í ž ľ š č(utf8) chars, but PHP code returns values with utf8 chars replaced by � , ? and other not readable chars. In html head I have set charset to utf-8. Please help me. I have this code:
//From config file
define ("DATABASE_SERVER", "localhost");
define ("DATABASE_LOGIN", "root");
define ("DATABASE_PASSWORD", "root");
define ("DATABASE_DATABASE", "novymost");
mysql_connect(DATABASE_SERVER, DATABASE_LOGIN, DATABASE_PASSWORD)or die(mysql_error());
mysql_select_db("novymost")or die(mysql_error());
$results=mysql_query("SELECT * FROM Downloads") or die(mysql_error());
$row = mysql_fetch_array( $result );
// Print out the contents of the entry
while($rows = mysql_fetch_array($results))
{
echo("<li>");
echo "<a href=\"".$rows["URL"];
echo("\">");
echo "".$rows["TITLE"];
echo(" - ".$rows["SIZE"]);
echo("</a>");
echo("<br/></li>");
}
run the query
mysql_query( "set names utf8" );
before runnign any other queries. This sets the connection charset
http://dev.mysql.com/doc/refman/5.0/en/charset-connection.html
In php:
header("Content-Type: text/html; charset=UTF-8");
In HTML:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
In Database before queries:
mysql_query( "set names utf8" );
Or you can also convert you latin-table to a UTF8-table:
INSERT INTO utf8table (utf8column)
SELECT CONVERT(latin1field USING utf8)
FROM latin1table;
I am learning PHP programming, so I have setup testing database and try to do various things with it. So situation is like that:
Database collation is utf8_general_ci.
There is table "books" created by query
create table books
( isbn char(13) not null primary key,
author char(50),
title char(100),
price float(4,2)
);
Then it is filled with some sample data - note that text entries are in russian. This query is saved as utf-8 without BOM .sql and executed.
insert into books values
("5-8459-0046-8", "Майкл Морган", "Java 2. Руководство разработчика", 34.99),
("5-8459-1082-X", "Кристофер Негус", "Linux. Библия пользователя", 24.99),
("5-8459-1134-6", "Марина Смолина", "CorelDRAW X3. Самоучитель", 24.99),
("5-8459-0426-9", "Родерик Смит", "Сетевые средства Linux", 49.99);
When I review contents of created table via phpMyAdmin, I get correct results.
When I retrieve data from this table and try to display it via php, I get question marks instead of russian symbols. Here is piece of my php code:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Books</title>
</head>
<body>
<?php
header("Content-type: text/html; charset=utf-8");
mysqli_set_charset('utf8');
# $db = new mysqli('localhost', 'login', 'password', 'database');
$query = "select * from books where ".$searchtype." like '%".$searchterm."%'";
$result = $db->query($query);
$num_results = $result->num_rows;
for ($i = 0; $i < $num_results; $i++) {
$row = $result->fetch_assoc();
echo "<p><strong>".($i+1).". Title: ";
echo htmlspecialchars (stripslashes($row['title']));
echo "</strong><br />Author: ";
echo stripslashes($row['author']);
echo "<br />ISBN: ";
echo stripslashes($row['isbn']);
echo "<br />Price: ";
echo stripslashes($row['price']);
echo "</p>";
}
...
And here is the output:

Can someone point out what I am doing wrong?
Can someone point out what I am doing wrong?
Yes, I can.
You didn't tell Mysql server, what data encoding you want.
Mysql can supply any encoding in case your page encoding is different from stored data encoding. And recode it on the fly.
Thus, it needs to be told of client's preferred encoding (your PHP code being that database client).
By default it's latin1. Thus, because there is no such symbols in the latin1 character table, question marks being returned instead.
There are 2 ways to tell mysql what encoding we want:
a slightly more preferred one is mysqli_set_charset() function (method in your case).
less preferred one is SET NAMES query.
But as long as you are using mysqli extension properly, doesn't really matter. (though you aren't)
Note that in mysql this encoding is called utf8, without dashes or spaces.
Try to set output charset:
SET NAMES 'utf-8'
SET CHARACTER SET utf-8
Create .htaccess file:
AddDefaultCharset utf-8
AddCharset utf-8 *
CharsetSourceEnc utf-8
CharsetDefault utf-8
Save files in UTF-8 without BOM.
Set charset in html head.
After your mysql_connect, set your connection to UTF-8 :
mysql_query("SET NAMES utf8");
Follow Alexander advices for .htaccess, header and files encoding
You probably need to call mysqli_set_charset('utf8'); after you set up your connection with new mysqli(...) as it works on a link rather than a global setting.
so..
# $db = new mysqli('localhost', 'login', 'password', 'database');
mysqli_set_charset($db, 'utf8');
$query = "select * from books where ".$searchtype." like '%".$searchterm."%'";
By the way, that query seems to be open to SQL-injection unless $searchterm is sanitized. Just something to keep in mind, consider using prepared statements.
And using # to suppress errors is generally not recommended, especially not during development. Better to deal with error-conditions.
after your mysql_query add
#mysql_query("SET character_set_server='utf8'; ");
#mysql_query("SET character_set_client='utf8'; ");
#mysql_query("SET character_set_results='utf8'; ");
#mysql_query("SET character_set_connection='utf8'; ");
#mysql_query("SET character_set_database='utf8'; ");
#mysql_query("SET collation_connection='utf8_general_ci'; ");
#mysql_query("SET collation_database='utf8_general_ci'; ");
#mysql_query("SET collation_server='utf8_general_ci'; ");
Try to put also in the HTML document Head the meta tag:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
this is different to the HTTP header header("Content-type: text/html; charset=utf-8");
