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:
<?php
include("config.php");
$global_dbh = mysql_connect($hostname, $username, $password)
or die("Could not connect to database");
mysql_select_db($db)
or die("Could not select database");
function display_db_query($query_string, $connection, $header_bool, $table_params) {
// perform the database query
$result_id = mysql_query($query_string, $connection)
or die("display_db_query:" . mysql_error());
// 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) {
print("<TR>");
for($column_num = 0; $column_num < $column_count; $column_num++) {
$field_name = mysql_field_name($result_id, $column_num);
print("<TH>$field_name</TH>");
}
print("</TR>\n");
}
// print the body of the table
while($row = mysql_fetch_row($result_id)) {
print("<TR ALIGN=LEFT VALIGN=TOP>");
for($column_num = 0; $column_num < $column_count; $column_num++) {
print("<TD>$row[$column_num]</TD>\n");
}
print("</TR>\n");
}
print("</TABLE>\n");
}
function display_db_table($tablename, $connection, $header_bool, $table_params) {
$query_string = "SELECT * FROM $tablename";
display_db_query($query_string, $connection,
$header_bool, $table_params);
}
?>
<HTML><HEAD><TITLE>Displaying a MySQL table</TITLE></HEAD>

<TABLE><TR><TD>
<?php
//In this example the table name to be displayed is static, but it could be taken from a form
$table = "submits";

but I get ???????? as the results:
Where is my mistake?
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");

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.
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'm a bit newbi in PHP. I implemented http://www.sanwebe.com/2013/03/loading-more-results-from-database solution in my new website: http://do2go.pl/do2go-nowa/
its working well - except encoding. My DB and all things are in UTF8. When fetch taking data from DB UTF8 seems not working.
Heres configuration and fetch code:
Config:
<?php
$db_username = 'kamio2_do2gonowa';
$db_password = 'JeremiasZ1!';
$db_name = 'kamio2_do2gonowa';
$db_host = 'localhost';
$item_per_page = 2;
mysqli_query ("SET NAMES 'utf8'"); mysqli_set_charset('utf8');
$connecDB = mysqli_connect($db_host, $db_username, $db_password,$db_name) or die('could not connect to database');
?>
And fetch:
<?php
include("config.inc.php"); //include config file
//sanitize post value
$page_number = filter_var($_POST["page"], FILTER_SANITIZE_NUMBER_INT, FILTER_FLAG_STRIP_HIGH);
header('Content-Type: text/html; charset=UTF-8');
//throw HTTP error if page number is not valid
if(!is_numeric($page_number)){
header('HTTP/1.1 500 Invalid page number!');
exit();
}
//get current starting point of records
$position = ($page_number * $item_per_page);
//Limit our results within a specified range.
$results = mysqli_query($connecDB, "SELECT id,introtext FROM w7wst_content ORDER BY id DESC LIMIT $position, $item_per_page");
//output results from database
echo '<ul class="page_result">';
while($row = mysqli_fetch_array($results))
{
echo '<li id="item_'.$row["id"].'"><span class="page_message">'.$row["introtext"].'</span></li>';
}
echo '</ul>';
?>
I added mysql_query ("SET NAMES 'utf8'"); mysql_set_charset('utf8'); but this does nothing. Still getting � symbols and ? instead of " All next 3 was changed directly in DB tables for html symbols which isn't a solution.
Any help appreciated! :)
(To close the question, since this was the solution to the OP's problem)
Add $connecDB->set_charset("utf8"); just before $results = mysqli_query($connecDB...
You are using mysql and mysqli in one script. Only use mysqli as mysql has been deprecated. That said try this:
mysqli_character_set_name($connectDB);
mysqli_set_char_set($connectDB, 'UTF8');
Set these after your connection script.
Did you check if they are properly stored in the table? Try typing this in your database(not in PHP):
SELECT * FROM w7wst_content;
and see if it's displaying properly. Alternatively you can check table contents with some tool like phpmyadmin. If it's not you have to set collation to something like utf8_general_ci.
EDIT: Also, how about setting the charset AFTER connecting to the database, hm? :)
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.
