Same dataset outputs different characters : phpmyadmin / own query - php

Im trying to get a some data from the db , but the output isn't what i expected.
Doing my own querying on the db , i get this output : string 'C�te d�Ivoire' (length=13)
Querying the db from phpmyadmin i get normal output : Côte d’Ivoire
php.ini default charset, mysql db default charset , <meta> charset are all set to utf-8 .
I can't fugire it out where the encoding is being made that i get different output with same configuration .
P.S. : using mysqli driver .

In the same page that gives you wrong results, try first running this instruction
print base64_encode("Côte");
The correct answer is Q8O0dGU.... If you get something else, like Q/R0ZQo..., this means that your script is working with another charset (here Latin-1) instead of UTF-8. It's still possible that also MySQL and also the browser are playing tricks, but the line above ensures that PHP and/or your editor are playing you false.
Next, extract Côte from the database and output its base64_encode. If you see Q8O0..., then the connection between MySQL and PHP is safely UTF8. If not, then whatever else might also be needed, you need to change the MySQL charset (SET NAMES utf8 and/or ALTER of table and database collation).
If PHP is UTF8, and MySQL is UTF8, and still you see invalid characters, then it's something between PHP and the browser. Verify that the content type header is sent correctly; if not, try sending it yourself as first thing in the script:
Header('Content-Type: text/html; charset=UTF8');
For example in Apache configuration you should have
AddDefaultCharset utf-8
Verify also that your browser is not set to override both server charset and auto-detection.
NOTE: as a rule of thumb, if you get a single diamond with a question mark instead of a UTF8 international character, this means that an UTF8 reader received an invalid UTF8 code point. In other words, the entity showing the diamond (your browser) is expecting UTF8, but is receiving something else, for example Latin1 a.k.a. ISO-8859-15.
Another difficult-to-track way of getting that error is if the output somehow contains a byte order mark (BOM). This may happen if you create a file such as
###<?php
Header("Content-Type: text/html; charset=UTF8");
?>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF8" />
</head>
<body>
Hellò, world!
</body>
</html>
where that ### is an (invisible in most editors) UTF8 BOM. To remove it, you either need to save the file as "without BOM" if the editor allows it, or use a different editor.

If you do your "own querying" with the command line tool mysql, you have to set the option --default-character-set=utf8, too. Otherwise, please tell us how you do your own querying.

Why does my output change?

I'm working with UTF-8 encoding in PHP and I keep managing to get the output just as I want it. And then without anything happening with the code, the output all of a sudden changes.
Previously I was getting hebrew output. Now I'm getting "&&&&&".
Any ideas what might be causing this?
These are most common problems:
Your editor that you’re creating the PHP/HTML files in
The web browser you are viewing your site through
Your PHP web application running on the web server
The MySQL database
Anywhere else external you’re reading/writing data from (memcached, APIs, RSS feeds, etc)
And few things you can try:
Configuring your editor
Ensure that your text editor, IDE or whatever you’re writing the PHP code in saves your files in UTF-8 format. Your FTP client, scp, SFTP client doesn’t need any special UTF-8 setting.
Making sure that web browsers know to use UTF-8
To make sure your users’ browsers all know to read/write all data as UTF-8 you can set this in two places.
The content-type tag
Ensure the content-type META header specifies UTF-8 as the character set like this:
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=UTF-8">
The HTTP response headers
Make sure that the Content-Type response header also specifies UTF-8 as the character-set like this:
ini_set('default_charset', 'utf-8')
Configuring the MySQL Connection
Now you know that all of the data you’re receiving from the users is in UTF-8 format we need to configure the client connection between the PHP and the MySQL database.
There’s a generic way of doing by simply executing the MySQL query:
SET NAMES utf8;
…and depending on which client/driver you’re using there are helper functions to do this more easily instead:
With the built in mysql functions
mysql_set_charset('utf8', $link);
With MySQLi
$mysqli->set_charset("utf8")
*With PDO_MySQL (as you connect)*
$pdo = new PDO(
'mysql:host=hostname;dbname=defaultDbName',
'username',
'password',
array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8")
);
The MySQL Database
We’re pretty much there now, you just need to make sure that MySQL knows to store the data in your tables as UTF-8. You can check their encoding by looking at the Collation value in the output of SHOW TABLE STATUS (in phpmyadmin this is shown in the list of tables).
If your tables are not already in UTF-8 (it’s likely they’re in latin1) then you’ll need to convert them by running the following command for each table:
ALTER TABLE myTable CHARACTER SET utf8 COLLATE utf8_general_ci;
One last thing to watch out for
With all of these steps complete now your application should be free of any character set problems.
There is one thing to watch out for, most of the PHP string functions are not unicode aware so for example if you run strlen() against a multi-byte character it’ll return the number of bytes in the input, not the number of characters. You can work round this by using the Multibyte String PHP extension though it’s not that common for these byte/character issues to cause problems.
Taken form here: http://webmonkeyuk.wordpress.com/2011/04/23/how-to-avoid-character-encoding-problems-in-php/
Try after setting the content type with header like this
header('Content-Type: text/html; charset=utf-8');
Try this function - >
$html = "Bla Bla Bla...";
$html = mb_convert_encoding($html, 'HTML-ENTITIES', "UTF-8");
for more - http://php.net/manual/en/function.mb-convert-encoding.php
I put together this method and called it in the file I'm working with, and that seemed to resolve the issue.
function setutf_8()
{
header('content-type: text/html; charset: utf-8');
mb_internal_encoding('UTF-8');
mb_http_output('UTF-8');
mb_http_input('UTF-8');
mb_language('uni');
mb_regex_encoding('UTF-8');
ob_start('mb_output_handler');
}
Thank you for all your help! :)

How to set the charset to UTF-8 for a received http variable in PHP?

How to set the charset to UTF-8 for a received http variable in PHP?
I have a html form using the POST methode with 1 input field. But when i submit the form and echo the retrieved the contents from the input field via $_POST['input_name'] i get this: KrkiÄ - but i entered (and i need) this: Krkič
So how can i fix this?
I figured it out now. :)
If i want to add the contents to MYSQL then i need to add this:
if(!$mysqli->set_charset("utf8")){
printf("Error loading character set utf8: %s\n",$mysqli->error);
}
If i just need to echo the contents then adding this meta tag
<meta charset="utf-8">
into html head is enough.
There is no global default charset in PHP -- lots of things are encoding-aware, and each needs to be configured independently.
mb_internal_encoding applies only to the multibyte string family of functions, so it has an effect only if you are already using them (you need to do so most of the time that you operate on multibyte text from PHP code).
Other places where an incorrectly set encoding will give you problems include:
The source file itself (saved on the disk using which encoding?)
The HTTP headers sent to the browser (display the content received as which encoding?)
Your database connection (which encoding should be used to interpret your queries? which encoding for the results sent back to you?)
Each of these needs to be addressed independently, and most of the time they also need to agree among themselves.
Therefore, it is not enough to say "I want to display some characters". You also need to show how you are displaying them, where they are coming from and what the advertised encoding is for your HTML.
you can use:
<meta charset="UTF-8" />
on top of your php file place this
header('Content-Type: text/html; charset="UTF-8"');

PHP/MySQL encoding problems. � instead of certain characters

I have come across some problems when inputting certain characters into my mysql database using php. What I am doing is submitting user inputted text to a database. I cannot figure out what I need to change to allow any kind of character to be put into the database and printed back out through php as it's suppose to.
My MySQL collation is: latin1_swedish_ci
Just before I send the text to the database from my form I use mysql_real_escape_string() on the data.
Example below
this text:
�People are just as happy as they make up their minds to be.�
� Abraham Lincoln
is suppose to look like this:
“People are just as happy as they make up their minds to be.”
― Abraham Lincoln
As mentioned by others, you need to convert to UTF8 from end to end if you want to support "special" characters. This means your web page, PHP, mysql connection and mysql table. The web page is fairly simple, just use the meta tag for UTF8. Ideally your headers would say UTF8 also.
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
Set your PHP to use UTF8. Things would probably work anyway, but it's a good measure to do this:
mb_internal_encoding('UTF-8');
mb_http_output('UTF-8');
mb_http_input('UTF-8');
For mysql, you want to convert your table to UTF8, no need to export/import.
ALTER TABLE table_name CONVERT TO CHARACTER SET utf8
You can, and should, configure mysql to default utf8. But you can also run the query:
SET NAMES UTF8
as the first query after establishing a connection and that will "convert" your database connection to UTF8.
That should solve all your character display problems.
The likeliest cause of the problem is that the database connection is set to latin1 but you are feeding it text encoded in UTF-8. The simplest way to solve this is to convert your input into what the client expects:
$quote = iconv("UTF-8", "WINDOWS-1252//TRANSLIT", $quote);
(What MySQL calls latin1 is windows-1252 in the rest of the world.) Note that many characters, such as the quotation dash U+2015 that you use there, cannot be represented in this encoding and will be converted into something else. Ideally you should change the column encoding to utf8.
An alternative solution: set the database connection to utf8. It doesn't matter how the columns are encoded: MySQL internally converts text from the connection encoding into the storage encoding, you can keep the columns as latin1 if you want to. (If you do, the quotation dash U+2015 will be turned into a question mark ? because it's not in latin1)
How to set the connection encoding depends on what library you are using: if you use the deprecated MySQL library it's mysql_set_charset, if MySQLi it's mysqli_set_charset, if PDO add encoding=utf8 to the DSN.
If you do this you'll have set the page encoding to UTF-8 with the Content-Type header.
Otherwise you would be having the same problem with the browser: feeding it text encoded in UTF-8 when it's expecting something else:
header("Content-Type: text/html; charset=utf-8");
The solutions provided are helpful if starting from scratch. Putting all possible connections to UTF-8 is indeed the safest. UTF-8 is the most used charset on the net for a variety of reasons.
Some suggestions and a word of warning:
copy the tables you want to sanitize with a unique prefix (tmp_)
although your db-connection is forced to utf8, check you General Settings collation, change to utf8_bin if that was not done yet
you need to run this on the local server
the funny char error is mostly due to mixing LATIN1 with UTF-8 configurations. This solution is designed for this. It could work with other used char-sets that LATIN1 but I haven't checked this
check these tmp_tables extensively before copying back to the original
Builds the 2 array needed for the magic:
$chars = get_html_translation_table(HTML_ENTITIES, ENT_QUOTES, "UTF-8");
$LATIN1 = $UTF8 = array();
while (list($key,$val) = each ($chars)) {
$UTF8[] = $key;
$LATIN1[] = $val;
}
Now build up the routines you need: (tables->)rows->fields and at each field call
$row[$field] = mysql_real_escape_string(str_replace($LATIN1 , $UTF8 , $row[$field]));
$q[] = "$field = '{$row[$field]}'";
Finally build up and send the query:
mysql_query("UPDATE $table SET " . implode(" , " , $q) . " WHERE id = '{$row['id']}' LIMIT 1");
change the MySQL collation to utf8_unicode_ci or utf8_general_ci, including the table and the database.
You will need to set your database in utf-8 yes. There is many ways to do it. By changin the config file, via phpmyadmin or by calling php function (sorry memory blank) right before insert and update the mysql.
Unfortunately, i think you will have to re-enter any data you entered before.
One thing you also need to know, from personnal experience, make sure all table with relation have the same collation or you won'T be able to JOIN them.
as reference: http://dev.mysql.com/doc/refman/5.6/en/charset-syntax.html
Also, i can be a apache setting. We've experienced the same issue on 'free-hosting' server as well as on my brother's server. Once switched to another server, all the charater's became neat. Verfiy you apache setting, sorry but i can't bting more light on apache's config.
Get rid of everything you just need to follow these two points, every problem regarding special languages characters will be resolved.
1- You need to define the collation of your table to be utf8_general_ci.
2- define <meta http-equiv="content-type" content="text/html; charset=utf-8"> in the HTML after head tag.
2- You need to define the mysql_set_charset('utf8',$link_identifier); in the file where you made connection with the database and right after the selection of database like 'mysql_select_db' use this 'mysql_set_charset' this will allow you to add and retrieve data properly in what ever the language it is.
If your text has been encoded and decoded with the wrong encoding and so the mojibake is actually "solidified" into unicode characters, then the solutions mentioned so far won't work. I ended up having success with the ftfy Python package to automatically detect/fix mojibake:
https://github.com/LuminosoInsight/python-ftfy
https://pypi.org/project/ftfy/
https://ftfy.readthedocs.io/en/latest/
>>> import ftfy
>>> print(ftfy.fix_encoding("(ง'⌣')ง"))
(ง'⌣')ง
Hopefully this helps people who are in a similar situation.

PHP UTF-8 Encoding in HTML Input Box

Here what is in database
Seilpendel für Tragsysteme
now i am loading it into textbox via AJAX but what loads into textbox is
Seilpendel f�r Tragsysteme
but i want correct string Seilpendel für Tragsysteme into inputbox
i have tried
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
but not its working
The correct way solving this problem is to configure database to use UTF8 as their character encoding in and out.
RUN The following query after connecting to the database, one time and everything should start working.
SET NAMES 'utf8';
Make sure the db is encoded in UTF8, or use utf8_encode() or utf8_decode() when loading data from db or when writing back.
make sure that you also save the file with UTF8 encoding
you can open it in notepad (or even better - notepad++)
and on the "Save As..." popup - select UTF8 instead of the default ANSI
if you're using notepad++ select utf-8 without BOM
if the file's encoding is ok make sure that the connection to the DB is in utf-8
you can do it by querying:
SET NAMES 'utf8'

UTF-8 display-issues in PhpMyAdmin-Gui

I've got the following problem with my PMA-GUI:
While the data submitted by PHP-Scripts to my database is displayed correctly, ONLY PMA displays several german Umlaut's (such as äüß, ..) as ü or ä
The problem occurs also while exporting tables to file..
MySQL: 5.0.51a-3ubuntu5.8
PMA: 3.4.5
Database & fields are utf8_general_ci
Does anybody know a solution?
Are you sure that your client is sending data as utf-8?
this seems to me a duplicate of:
German Umlaute in Mysql/Phpmyadmin
You need to ensure you use consistent use of character set/character encoding.
For example, to normalise to UTF-8 content, your DB fields' character sets should be set to UTF-8. Then, in your PHP (if you have your own scripts running that fetch DB information) you need to then add to the head section:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
Then, in the PHP, before any output to the browser, include the content type PHP header:
header ('Content-type: text/html; charset=utf-8');
Before you run any SQL to fetch content (so after you connect, but before executing your query), use mysql_set_charset:
mysql_set_charset('utf8',$link);
// $link is optional, refers to your DB connection
You can think of it as three steps:
The step used to add the characters to your DB
Storage of characters in your DB
Retrieval and display of characters
The simplest bet to ensure conformity and that characters display as you anticipate, is to ensure the correct, consistant, character set is defined at each stage.
