Use of MySQL persistent connection in ZF2 - php

Question

On ZF2 I need to use a persistent MySQL connection and reconnect and the MySQL is gone away.
But I can not figure out where I should activate the MYSQL_OPT_RECONNECT parameter.
My db adapters are definied as follow:
'db' => array(
'driver' => 'Pdo',
'dsn' => 'mysql:dbname=DB_NAME;host=HOST',
'driver_options' => array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\'',
),
'username' => 'LOGIN',
'password' => 'PWD',
),
I have tried things like :
'db' => array(
'driver' => 'Pdo',
'dsn' => 'mysql:dbname=DB_NAME;host=HOST',
'driver_options' => array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\'',
'AUTO_RECONNECT_ON_UNSERIALIZE' => 1,
),
'options' => array(
'AUTO_RECONNECT_ON_UNSERIALIZE' => 1,
),
'username' => 'LOGIN',
'password' => 'PWD',
),
and nothing works.
How to make this mysql_options(&mysql, MYSQL_OPT_RECONNECT, &reconnect);
happen somewhere ?

Answer 1

Ok, the answer is :
'db' => array(
'driver' => 'Pdo',
'dsn' => 'mysql:dbname=DB_NAME;host=HOST',
'driver_options' => array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\'',
),
'options' => array(
PDO::ATTR_PERSISTENT => true',
),
'username' => 'LOGIN',
'password' => 'PWD',
),
But the use of persistant connection might not be a good fit for every one so you can also catch any "Mysql Server Gone Away Error" and proceed to a reconnect via :
$this->tableGateway->getAdapter()->getDriver()->getConnection()->disconnect();
$this->tableGateway->getAdapter()->getDriver()->registerConnection($this->getAdapter()->getDriver()->getConnection()->connect());
if($this->tableGateway->getAdapter()->getDriver()->getConnection()->isConnected()) {
return true;
}
