How to define the use of utf-8 in Doctrine 2 in Zend Framework application.ini, when using Bisna

Question

The following ZendCasts cast, shows a way to use doctrine 2 in a zend framework environment.
Using this configuration, how can I make the connection use a utf-8 charset so the magic of "SET NAMES 'utf8'" will happen ?

What I'm really searching for is a way to configure it using the application.ini file.
If that's not possible using this configuration, how can this be done by code ? an _initDoctrine method in the Bootstratp file ?

Thank you.

UPDATE
It appears there's a post connect event which handles this, but I don't see how can I set it up via application.ini (if possible at all).
If not, can I set it up via a bootstrap method ? Will the bootstrap method run before any other doctrine connection code run, when relying on the Bisna library ?

Solution 1

works fine for me

resources.doctrine.dbal.connections.default.parameters.driverOptions.1002 = "SET NAMES 'UTF8'"

1002 is the integer value of PDO::MYSQL_ATTR_INIT_COMMAND:

Command to execute when connecting to the MySQL server. Will automatically be re-executed when reconnecting. Note, this constant can only be used in the driver_options array when constructing a new database handle.

If you are not using Bisna, you could simply do something like the following:

Pass the config stuff directly to EntityManager's connection options (although driverOptions is not documented)

// $options is a simple array to hold your data
$connectionOptions = array(
    'driver'   => $options['conn']['driv'],
    'user'     => $options['conn']['user'],
    'password' => $options['conn']['pass'],
    'dbname'   => $options['conn']['dbname'],
    'host'     => $options['conn']['host'],
    'charset'  => 'utf8',
    'driverOptions' => array(
        1002 => 'SET NAMES utf8'
    )
);

$em = \Doctrine\ORM\EntityManager::create($connectionOptions, $config);

I'm using the following custom bootstrap resource to initialize doctrine therefore $options is in application.ini and is accessible there by $this->getOptions();

// \library\My\Application\Resource\Doctrine.php
class My_Application_Resource_Doctrine extends Zend_Application_Resource_ResourceAbstract
 {

    public function init()
    {
       $options = $this->getOptions();
       $config = new \Doctrine\ORM\Configuration();
       //doctrine autoloader, config and other initializations
       ...
       $connectionOptions = array(
               .... //see above
       );
       $em = \Doctrine\ORM\EntityManager::create($connectionOptions, $config);
       $registry = Zend_Registry::getInstance();
       $registry->em = $em;
       return $em;
    }
}

It will bootstrap automatically if you put in application.ini

resources.doctrine.conn.host = '127.0.0.1'
resources.doctrine.conn.user = '...'
resources.doctrine.conn.pass = '...'
....

this worked for me. config/autoload/doctrine.local.php

<?php
return array(
    'doctrine' => array(
        'connection' => array(
            'orm_default' => array(
                'driverClass' => 'Doctrine\DBAL\Driver\PDOMySql\Driver',
                'params' => array(
                    'host' => 'localhost',
                    'port' => '3306',
                    'user' => '...',
                    'password' => '...',
                    'dbname' => '...',

                    'driverOptions' => array(
                        \PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8'
                    )

                ),

            )
        )
    )
);

Solution 4

It is possible to add it via application.ini, provided you use ZendX_Doctrine2 (at https://github.com/mridgway/ZendX_Doctrine2) with MySQL.

Then here's the line you need in application.ini:

resources.entitymanagerfactory.connectionOptions.driverOptions.1002 = "SET NAMES utf8"

(1002 == PDO::MYSQL_ATTR_INIT_COMMAND)

Don't forget to correctly set

default-character-set=utf8

in your my.cnf

Solution 5

Since this is for Doctrine 2, and ZendCasts is using Bisna, I believe you can just add this to your configuration.ini file

resources.doctrine.dbal.connections.default.parameters.driverOptions.charset = "utf8"

I'm not exactly sure how to test if it is sticking or not but let us know.

You are correct regarding the use of Bisna, and the line you gave does have it's affect. However - according to doctrine-project.org/docs/dbal/2.0/en/reference/events.html, there's a post connect event to which I need to subscribe a MysqlSessionInit object with the utf-8 charset. Any idea ?

You are The Man! Thanx! Solution for "How to set Doctrine2 to connect to MySql using UTF-8 charset".

[Eddie C.]

Thank you. I suggest to change the line 1002 => 'SET NAMES utf8' into PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8'

[Imeksbank]

Thank you. Works in Zend Expressive 3 as well.
