How to use UTF-8 with Firebird and PHP Data Objects (PDO) - php

With mysql I can just do this to solve the problem:
$diveOptions = array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"); // set names utf-8 and works well
$pdo = new PDO('mysql:host=mysql.example.com;dbname=example_db',"username","password",diveOptions);
But I can't do the same with the firebird's pdo connection.
How can I solve this problem of UTF-8?
Already tried charset=utf8 in pdo configuration don t work too..
$str_conn = "firebird:dbname=C:\db\banco.gdb;charset=utf8;host=localhost";
$dbh = new PDO($str_conn, "SYSDBA", "masterkey");
In my db was set to nome like this:
DEFAULT CHARACTER SET NONE COLLATION NONE;

Prevent special characters replacement into my DB with PHP

When I save François into my DB, it becomes François.
How can I prevent it to keep François ?
During my PDO connection I already use PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8".
Thanks.

you can change charset to utf8 after starting PDO connection.
$pdo_object = new PDO(...);
$pdo_object->exec("SET NAMES 'utf8'; SET CHARSET 'utf8'");

PDO, mysql, utf8 (arabic text) doesnt show in php

I have the following php code. Connection is OK but it doesn't show the Arabic text stored in the database correctly. Just question marks.
$mysqlPDO = new PDO('mysql:host='.HOSTNAME.';charset=utf8;dbname='.DBNAME.'',DBUSERNAME, DBPASSWORD, array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES UTF8"));
$stmt = $mysqlPDO->prepare("SHOW TABLES LIKE 'main_patches_version'");
$stmt->execute();
The DB collation is already set to utf8_general_ci and the table has utf8 as charset.
This application is calling Zend libraries which I'm not aware of.
I checked that the HTML has utf8 as encoding type. any suggestion?
I'm using xampp server, php version 5.5.11, mysql version 5.6.16

I found the solution here
http://akrabat.com/php/utf8-php-and-mysql/
I unmarked
character_set_server=utf8 from my.ini file and it works.
Thanks all

Make sure your DB collation is set to use utf8_general_ci or utf8mb4_general_ci.

why am i getting this £10 using charset=utf8

If i enter a £ (UK Pound Symbol) into my DB why does it always add to the database with as £.
I thought this was down to the charset but thought utf8 should cure this
EDIT i am setting the charset as below
$db = new PDO('mysql:host='.DBHOST.';dbname='.DBNAME.';charset=utf8', DBUSER, DBPASS);
any advice please.

Use this before any other query
SET NAMES utf8;

How to properly display non-redable characters stored in a MySQL Database

I have São Tomé and Príncipe stored in a MySQL database.
It displays on my web page as S�o Tom� and Pr�ncipe
Is there anyway to display it properly straight from the database?
My MySQL Type is MyISAM and the collation is utf8_general_ci
My web page charset is <meta charset="utf-8">
Field type is set to varchar(30) and field collations is same as table utf8_general_ci
PHP FUNCTION TESTS
utf8_decode() converted characters to S?o Tom? and Pr?ncipe
htmlspecialchars_decode() converted characters to S�o Tom� and Pr�ncipe
html_entity_decode() converted characters to S�o Tom� and Pr�ncipe
quoted_printable_decode() converted characters to S�o Tom� and Pr�ncipe
htmlentities() returned blank result
GOT IT TO WORK THANKS TO #SAEVEN
Ran this right before my query SELECT
mysqli_query($GLOBALS['db_link'], "SET NAMES 'utf8'");

Could it be that you need to specify your namespace collation at the connection level?
I assume that you've covered the basics, you've got the charset as utf8 in your HTML markup.
Try executing this SQL statement before you do any of your database queries:
'SET NAMES utf8'
e.g., if you are using PDO
// do your regular connection logic whatever it is
$dbc = new PDO( .... );
$dbc->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$dbc->query( 'SET NAMES utf8' );
// run your queries beneath
....
or can use the shorthand
new PDO(
'mysql:host=mysql.example.com;dbname=awesome_db',
"username",
"password",
array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8")
);
Whatever DBAL you use, that query'll work. Just run it on the same connection you use to pull your data, before pulling it (only needs to be done once)

PDO + MySQL and broken UTF-8 encoding [duplicate]

This question already has answers here:
UTF-8 all the way through
(13 answers)
Closed 5 months ago.
I use the PDO library with a MySQL database in PHP, but if I insert any data encoded in UTF-8, like Arabic words, it’s inserted into the database, but as ?????????.
In my own framework, after I create the PDO connection, I send two queries – SET NAMES utf8 and SET CHARACTER SET utf8. It still doesn’t work.
Example:
loadclass('PDO', array(
sprintf(
'mysql:host=%s;port=%s;dbname=%s',
confitem('database', 'host'),
confitem('database', 'port'),
confitem('database', 'name')
),
confitem('database', 'username'),
confitem('database', 'password'),
array('PDO::ATTR_PERSISTENT' => confitem('database', 'pconnect'))
));
$this->query('SET NAMES ' . confitem('database', 'charset'));
$this->query('SET CHARACTER SET ' . confitem('database', 'charset'));
Workaround: Use the json_encode function to convert data before inserting it to the database, and use json_decode to decode it after fetching. This is how I do it now.

Warning: This answer applies to PHP 5.3.5 and lower. Do not use it for PHP version 5.3.6 (released in March 2011) or later.
Compare with Palec's answer here.
Use:
$pdo = new PDO(
'mysql:host=hostname;dbname=defaultDbName',
'username',
'password',
array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8")
);
It forces UTF-8 on the PDO connection. It worked for me.

You have to set the correct character set for the connection. Add the charset=utf8 option to the DSN (this is MySQL-specific!)
$pdo = new PDO(
'mysql:host=hostname;dbname=defaultDbName;charset=utf8',
'username',
'password'
);
However, in PHP versions before 5.3.6 (released in March 2011), you must use a workaround as the charset option in the DSN is not supported.
$pdo = new PDO(
'mysql:host=hostname;dbname=defaultDbName',
'username',
'password',
array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8")
);

All attempts like:
PDO::MYSQL_ATTR_INIT_COMMAND =>"SET NAMES 'utf8mb4' COLLATE 'utf8mb4_unicode_ci' "
or
$this->connection = new PDO('mysql:host='.DBHOST.';dbname='.DBNAME.';charset=utf8', DBUSER, DBPASS, self::$opt);
or
$this->connection->exec("set names utf8");
still generated unreadable text mess.
In my case, the cause of the problem was: htmlentities used prior to inserting data into a database.
Cyrillic letters were destroyed completely.

Try setting the default_charset value in php.ini to UTF-8. Or you can set it using the ini_set function.
Also, if the input is coming through form submissions, make sure your web pages are set to UTF-8 using the meta tag.

When interacting with mysql or mariadb, charset 'utf8' is not correct. You need to use utf8mb4. Due to historical issues, utf8 in mysql/mariadb is an alias to utf8mb3 which can only contain a subset of utf8 (3 bytes instead of 4)
So adding 'charset=utf8mb4' to your PDO DSN connection string is the correct thing to do for recent PHP versions, NOT charset=utf8.
For example, the poop emoji in full color: 💩 cannot be stored if the column and PDO are not utf8mb4.
