Problems with swedish letters MySQL and LAMP - php

I have struggled with this some time. I could not get it to work.
On the url http://course.easec.se/problem.pdf I have put together what I have done so far!
Any suggestions?
<?php
header('Content-Type: text/html; charset=ISO-8859-1'); //no changes
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "db_test4";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
mysqli_set_charset("utf8");
echo "From PHP Script ååååå\n"; //to see if there is problem when edit the script
$sql = "SELECT * FROM test_tbl";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "Kundid: " . $row["kund_id"]. " - Förnamn: " . $row["fnamn"]. " - Efternamn: " . $row["enamn"]. " - Adress:" . $row["adress1"] ."<br>";
}
} else {
echo "0 results";
}
$conn->close();
?>
Client:
It works now, seems do be my editor, when I tried ANSI instead of UTF-8 and Changes the header to !
enter image description here

Directly below
$conn = new mysqli($servername, $username, $password, $dbname);
add
$conn->set_charset("utf8");
Note: In addition you should also make sure that the charset of your HTML (in the <head> tag) is set to utf-8, like <meta charset="utf-8">

Use:
header('Content-Type: text/html; charset=ISO-8859-1');
Instead of:
header('Content-type: text/html; charset=utf-8');
No need to use inside while loop, use top of the page before print anything.

I like how you set your question in a PDF, somewhat original :-D . Now, the answer to your problem will be found here. Read the whole question and as many of the answers as you can.
then as a last effort I change editor to ANSI instead of UTF-8 then it works!
Due to this the issue is your internal PHP script encoding so Reaseach using PHP Multibyte String and setting your PHP code to :
<?php
mb_internal_encoding('UTF-8'); //this is the important one!
mb_http_output('UTF-8');
mb_http_input('UTF-8');
to ensure your PHP code is also UTF-8 complient when executed. You can also (or should be able to) edit the settings in your IDE editor to save PHP files without UTF-8 BOM (Byte Order Mark) which will also solve this problem and save them as UTF-8 understandable by other services.
Additional Notes (cos I like to moan about MySQL UTF-8):
MySQL UTF-8 is NOT the full UTF-8 . Solutions are offered in the linked thread above, some general additions:
1) You want to always use UTF8mb4 (and ideally _unicode_ci).
2) In the final screenshot of your PDF you should to set as many of these as practical to utf8mb4_unicode_ci.
3) Setting the connection character set is vital, even if the server and the client both use utf8mb4 if the connection is only utf-8 it brings everything else down to that low point.
4) Recommended:
header('Content-Type: text/html; charset=UTF-8'); //UTF-8
Only MySQL UTF-8 is broken, other implementatios of it is not and is perfectly usable as and is generally regarded as an HTML standard.

MySQL SELECT on Arabic Word returns 0 results on PHP but does on SQLBuddy/phpMyAdmin

Problem
I am getting 0 results when searching for an Arabic word in a MySQL database using the SELECT query with PHP.
However, the same exact query yields results in alternative clients, namely SQLBuddy and the likes. Everything is encoded in UTF-8.
Code
<?php
$host = "localhost";
$username = "hans_wehr_client";
// i know my security is a joke :)
$password = "hans_wehr";
$database = "hans_wehr";
$conn = new mysqli($host, $username, $password, $database);
if ($conn == TRUE){
$search = $_GET["search"];
$encoded_search = utf8_encode($search);
echo $encoded_search."<br>";
header('Content-Type: text/html; charset=utf-8');
$sql = "SELECT * FROM dictionary WHERE ARABIC LIKE '$search'";
echo $sql."<br>";
mysqli_query($conn,"SET NAMES 'utf8'");
mysqli_query($conn,'SET CHARACTER SET utf8');
$result = mysqli_query($conn, $sql);
if (mysqli_num_rows($result) > 0) {
// output data of each row
while($row = mysqli_fetch_assoc($result)) {
header('Content-Type: text/html; charset=utf-8');
echo $row["ARABIC"]. " - Meaning: " . $row["ENGLISH1"]. " " . $row["ENGLISH2"]. "<br>";
}
}else {
echo "0 results";
}
}
?>
Before the mods get the pitchforks, I have to clear up my troubleshooting logic.
Encoding. I set the page encoding to utf-8 using header('Content-Type:
text/html; charset=utf-8'); and ran the queries mysqli_query($conn,"SET NAMES 'utf8'"); and mysqli_query($conn,'SET CHARACTER SET utf8');, this cleared up the ??????? and Ùؤتا
rendered instead of Arabic words issue. That is kind of a different
issue. Source. and Source2.
Database Charset. My database and columns are set to UTF-8.
Other clients work. SQLBuddy/MySQL native client/ PHPMyAdmin appear to be working because running the same exact query yields result. Therefore I appear to be on the same bloody boat with him. The query SELECT * FROM dictionary WHERE ARABIC LIKE 'آخَر، أُخرى' returns a result on SQLbuddy but nada on PHP.
Possible solution:
Running the query SELECT * FROM dictionary WHERE ARABIC LIKE 'آخَر، أُخرى' yields me a result.
However running the query with a UTF-8 encoded version of the Arabic word returns 0 results. SELECT * FROM dictionary WHERE ARABIC LIKE 'آخَر، أُخرى' I think this simulates PHP.
The UTF-8 Arabic word version is obtained by decoding the automatically URL encoded $[_GET] parameter i.e %26%231570%3B%26%231582%3B%26%231614%3B%26%231585%3B%26%231548%3B+%26%231571%3B%26%231615%3B%26%231582%3B%26%231585%3B%26%231609%3B
Could it be that the MySQLi actually queries the UTF-8 version instead of the actual Arabic word? Therefore finding no match since they are different?
If so how can I explicitly tell PHP not to URL encode my search term and therefore pass it as it is?
Since according to my tinfoil theory, http://localhost/hans_wehr/search_ar.php?search=آخَر، أُخرى would work but http://localhost/hans_wehr/search_ar.php?search=%26%231570%3B%26%231582%3B%26%231614%3B%26%231585%3B%26%231548%3B+%26%231571%3B%26%231615%3B%26%231582%3B%26%231585%3B%26%231609%3B
Inputs will be greatly appreciated.
Use html_entity_decode():
Use html_entity_decode() on your $_GET["search"] value
<?php
$host = "localhost";
$username = "hans_wehr_client";
// i know my security is a joke :)
$password = "hans_wehr";
$database = "hans_wehr";
$conn = new mysqli($host, $username, $password, $database);
if ($conn == TRUE){
$search = $_GET["search"];
$encoded_search =html_entity_decode($search, ENT_COMPAT, 'UTF-8');
echo $encoded_search."<br>";
header('Content-Type: text/html; charset=utf-8');
$sql = "SELECT * FROM dictionary WHERE ARABIC LIKE '$encoded_search'";
echo $sql."<br>";
mysqli_query($conn,"SET NAMES 'utf8'");
mysqli_query($conn,'SET CHARACTER SET utf8');
$result = mysqli_query($conn, $sql);
if (mysqli_num_rows($result) > 0) {
// output data of each row
while($row = mysqli_fetch_assoc($result)) {
header('Content-Type: text/html; charset=utf-8');
echo $row["ARABIC"]. " - Meaning: " . $row["ENGLISH1"]. " " . $row["ENGLISH2"]. "<br>";
}
}else {
echo "0 results";
}
}

Php mysql returning?

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?

sql data charset / charactter set , set names not working

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 احمد Ø´Ûید Ú©ÛŒ صحیح 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>

Problems in inserting utf-8 string into database and then outputting it to web page

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");

I have a mysql table with contents
the structure is here:
I want to read and print the content of this table to html
This is my code:

// find out the number of columns in result
$column_count = mysql_num_fields($result_id)
or die("display_db_query:" . mysql_error());
// Here the table attributes from the $table_params variable are added
print("<TABLE $table_params >\n");
// optionally print a bold header at top of table
if($header_bool) {

Four good steps to always get correctly encoded UTF-8 text:
1) Run this query before any other query:
mysql_query("set names 'utf8'");
2) Add this to your HTML head:
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
3) Add this at top of your PHP code:
header("Content-Type: text/html;charset=UTF-8");
4) Save your file with UTF-8 without BOM encoding using Notepad++ or any other good text-editor / IDE.
Set the charset as utf8 as follows:
$conn = new mysqli($servername, $username, $password, $dbname);
$conn->set_charset("utf8");
You are not defining your HTML page as UTF-8. See this question on ways to do that.
You may also need to set your database connection explicitly to UTF8. Doing a
mysql_query("SET NAMES utf8;");
^
Put it right under your database connection script or include and MAKE sure you have it placed before you do any necessary queries. Also, for collocation please take the time to make sure your
setting it for your proper syntax type and general_ci seems working good for me when used. As a finale, clear your cache after banging your head, set your browser to proper encoding toolbar->view->encoding
Setting the connection to UTF8 after establishing the connection takes care of the problem. Don't do this if the first step already works.
UTF-8 content from MySQL table with PDO
To correctly get latin characters and so on from a MySQL table with PDO,
there is an hidden info coming from a "User Contributed Note" in the PHP manual website
(the crazy thing is that originally, that contribution was downvoted, now luckily turned to positive .. sometime some people need to got blamed)
my credits credits go to this article that pulled the solution and probably made that "User Contributed Note" to turn positive
If you want to have a clean database connection with correct Unicode characters
$this->dbh = new PDO(
"mysql:host=".DB_HOST.";dbname=".DB_NAME.";charset=utf8",
DB_USER,
DB_PASS);
try this :
mysql_set_charset('utf8', $yourConnection);
Old ways have been deprecated. If you are using PHP > 5.0.5 and using mysqli the new syntax is now:
$connection->set_charset("utf8")
Where $connection is a reference to your connection to the DB.
I tried several solutions but the only one that worked
is that of Hari Dass:
$conn->set_charset("utf8");
