Save Accents in MySQL Database - php

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.

why does my html not display special characters taken from my database

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'");

UTF-8 and German characters?

I have problem with German characters on my web site,
in html/php part of website i have this code to set utf-8:
<meta charset="utf-8">
in mysql, i have this code to set utf-8
SET CHARSET 'utf8';
Here is some word on German: Gemäß
Here is how that word looks in mysql table:
Gemäß
Here is how that word is shown on the site: Gemäß
What is a problem? Thanks.
I was using this code to get title:
$title = mysql_real_escape_string(htmlentities($_POST['title']));
I just override that to
$title = $_POST['title'];
At first, make sure, that you have UTF-8 characters in your database.
After that, try using SET NAMES 'UTF8' after connecting to MySQL:
$con=mysqli_connect("host", "user", "pw", "db");
if (!$con)
{
die('Failed to connect to mySQL: ' .mysqli_connect_errno());
}
mysqli_query($con, "SET NAMES 'UTF8'") or die("ERROR: ". mysqli_error($con));
As the manual says:
SET NAMES indicates what character set the client will use to send SQL
statements to the server... It also specifies the character set that the server should
use for sending results back to the client.
Try SET NAMES 'utf8' or SET NAMES 'utf-8'. Some of these works fine for portuguese, probably for german too. I just can't remember which one is correct, but if it is not, an error will be produced.
you should make sure that the CONNECTION is also utf-8.
with mysqli this is done with something like this:
$connection = mysqli_connect($host, $user, $pass, $db_name);
$connection->set_charset("utf8");
Now if somehow you ended up with wrong characters in the database there is a way to make it right:
in a PHP script, retrieve the information as you do now, i.e without setting the connection. This way the mistake will be inverted and corrected and in your php file you will have the characters in the correct utf-8 format.
in a PHP script, write back the information with setting the connection to utf-8
at this point you should see the character correct in your database
now change all your read/write functions of your site to use the utf-8 from now on
in HTML5 use
<meta charset="utf-8">
in HTML 4.0.1 use
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
the results are html entity encoded as if they were processed by htmlentities(), I wonder if your variables are ibserted as received from the form or are being processed by say a wysiwg editor for instance?
Anyway, these should print fine on an html template but an html_entity_decode() should do it to.
Hope this helps
Set the data type in your database to use UTF-8 as well, this should solve the problem.
I had the same problem. which I solved by using:
if you have already created your table, you need the modify the character set as:
alter table <table name> convert to character set utf8 collate utf8_general_ci.
your tables character set is set to latin_swedish by default by MySQL.
also, you might face some problems while retrieving the data and displaying it to you page.For that include: mysql_set_charset('utf8') just below the line where you have connected your database.
eg:
mysql_connect('localhost','root','');
mysql_select_db('my db');
mysql_set_charset('utf8');
You will need to do this for php 5.x
$yourNiceLookingString =
htmlspecialchars ($YourStringFromDB, ENT_COMPAT | ENT_HTML401, 'ISO-8859-1');
and for php 4.x
$yourNiceLookingString = htmlspecialchars($YourStringFromDB);

Can not insert french string in database mysql php

I have form with input text, when i add text
Un sac à main de femme recèlerait une quantité importante de bactéries
it adds in database only Un sac
i have tried with addslashes, mysql_real_escape_string, htmlspecialchars etc. also using UTF-8 encoding, but still it can not insert whole string
YOu should use utf8_unicode_ci as your column's collation in orer for French strings to be added in it.
In order to store non-US strings in the database, you must ensure that each of the following 3 steps are correctly implemented:
You database table must be set to a charset compatible with French. To be future proof, I recommend creating tables with UTF-8. For more information see the MySQL documentation.
Your database connection must be set to a proper character set both when storing and when querying. To do this, use mysqli_set_charset() (or whatever your MySQL connector offers).
Your input form AND your view page must be served with the exact character set as your data. To do that, you will need to set the following header: header('Content-Type: text/html; charset=UTF-8'); (If you are using a different charset, change it accordingly.)
You can of course use a different character set for storage and representation but why would you want to do that?
Also, when working with databases and HTML, you should consider:
ALWAYS escape your data as it goes into the database. Use mysqli_real_escape_string() or whatever escape method your database connector offers. Also, do NOT set the connection charset by using SET NAMES UTF8, otherwise your connector library will not know what charset to use for escaping. For more information google "sql injection".
ALWAYS escape your data as it goes into HTML with htmlspecialchars(). Also pay attention to ALWAYS provide the correct character set. For more information google "xss".
After breaking my head for 2 days straight and reading all the possible answers here's what solved the problem and allows me to insert additional weird characters like em dash etc. and retrieve data without seeing weird characters.
Here's the complete step-by-step setup.
The collation of the db column need to be: utf8_general_ci
The type is: varchar(250)
In the PHP header set the default client character set to UTF8
mysql_set_charset("UTF8", $link);
Set the character set result so we can show french characters
$sql = "SET character_set_results=utf8";
$result = mysql_query($sql);
In the html header specify, so you can view the french characters:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
When inserting the data do NOT use utf8_decode, just the below will work fine
$query = 'insert into tbl (col) VALUES ("'.mysql_real_escape_string($variable).'");
Use normal queries to retreive data, example query:
$query = "select * from table;";
Finally got this fixed, hope this is helpful to others.
In the php:
header ('Content-type: text/html; charset=utf-8');
After connection:
mysql_set_charset("utf8");
Just to follow up with this, I was using dbForge Studio and just pasting in French text and I had all the collations/encoding set properly. The one thing I didn't have set was the actual encoding for the connection to the db. Set it to UTF8 and all was well again. #2 in #Janoszen answer.
Had the same problem. The input text came from ANSII file, so it wasn't quite UTF8, despite all my utf8 settings. utf8_encode(input_text) solved it.
I have tried
htmlentities()
. .it saves the string as it is in the database
You should try this to insert special character in mysql :
$con = mysql_connect($server,$uname,$pass);
$res = mysql_select_db($database,$con)
mysql_set_charset("letin1", $con);

MySQL: ucs2_slovenian_ci to utf-8 on webpage

I have a MySQL database with tables in ucs2_slovenian_ci encoding. I would like to write content of tables on utf-8 encoding webpage. So far I tried with:
mysql_set_charset ("utf-8");
mysql_query("SET NAMES 'utf-8'");
...
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
...
<?php echo utf8_encode($text); ?>
...
I'm still geting weird signs (question marks) instead of letters Š,Č,Ž
Nothing seems to work.
Weird thing is that with php command mysql_client_encoding($link) it says I have latin1 encoding. When I look page in Firefox it says UTF-8. What's wrong?
Please help.
ucs2_slovenian_ci encoding
That is not an encoding but a collation. A collation is the information on how something is sorted.
For your website, this isn't even of interest, because that's what the database knows about itself - or better: the data stored in itself.
For your website script's it's more important that you tell your database which encoding you need - here: UTF-8.
You signal that the database server by specifying the database client encoding. Consult your database client driver manual how to specify that. It could be that:
mysql_set_charset("utf8", $link);
Take care: it's utf8 while officially it's written UTF-8. That's something special with the MySQL database, write UTF-8 as utf8 when you set that parameter.
Do not use:
mysql_query("SET NAMES 'utf-8'");
because it's deprecated (not good, see as well the PHP manual and Whether to use “SET NAMES”).
And if you tell the database client which encoding you expect, you don't need to encode your own, like this:
utf8_encode($text);
Remove that stuff, you don't need it.
First add header('Content-Type: text/html; charset=utf-8');
and
mysql_set_charset ("utf-8");
should be:
$db = mysql_connect($hostname,$username,$password);
mysql_set_charset ("utf8", $db);
Also make sure what in MySQL DB everything in utf-8
Anyways you may play with:
mb_convert_encoding($string, "Other encoding", "UTF-8");

UTF-8 problems PHP/MySQL

I've always used ISO-8859-1 encoding, but I'm now going over to UTF-8.
Unfortunately I can't get it to work.
My MySQL DB is UTF-8, my PHP document is encoded in UTF-8, I set a UTF-8 charset, but it still doesn't work.
(it is special characters like æ/ø/å that doesn't work)
Hope you guys can help!
Make sure the connection to your database is also using this character set:
$conn = mysql_connect($server, $username, $password);
mysql_set_charset("UTF8", $conn);
According to the documentation of mysql_set_charset at php.net:
Note:
This is the preferred way to change the charset. Using mysql_query() to execute
SET NAMES .. is not recommended.
See also: http://nl3.php.net/manual/en/function.mysql-set-charset.php
Check the character set of your current connection with:
echo mysql_client_encoding($conn);
See also: http://nl3.php.net/manual/en/function.mysql-client-encoding.php
If you have done these things and add weird characters to your table, you will see it is displayed correct.
Remember to set connection encoding to utf8 as well.
In ext\mysqli do
$mysqli->set_charset("utf8")
In ext\mysql do
mysql_set_charset("utf8")
With other db extensions you might have to run query like
SET NAMES 'utf8'
Some more details about connection encoding in MySQL
As others point out, making sure your source code is utf-8 encoded also helps. Pay special attention to not having BOM (Byte Order Mark) - it would be sent to browser before any code is executed, so using headers or sessions would become impossible.
After connecting to db, run query SET NAMES UTF8
$db = new db(...);
$db->query('set name utf8');
and add this tag to header
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
Are you having this error? MySql SELECT UNION Illegal mix of collations Error? Just set you entire mysql to utf 8 then
SET character_set_connection = utf8;
Try this after connecting to mysql:
mysql_query("SET NAMES 'utf8'");
And encode PHP document in UTF-8 without BOM.
I had the same problem but now its resolved. Here is the solution:
1st: update ur table
ALTER TABLE tbl_name
DEFAULT CHARACTER SET utf8
COLLATE utf8_general_ci;
2nd:
add this in the head section of the HTML code:

Nowadays PDO is the recommended way to use mysql. With that you should use the connection string to set encoding. For example: "mysql:host=$host;dbname=$db;charset=utf8"
