How to get Exception executing select statement ZF2 - php

Question

I'm getting a problem using ZF2 and DbAdapter.
I'm making a select statement and trying to get te exception when happen some error.
I have my select statement inside a block try... catch... but the problem is when I set a "wrong query", the exception is not threw.
Here my service:
return array(
'db' => [
'driver' => 'Pdo',
'dsn' => 'mysql:dbname=my_dbname;host=localhost',
'username' => 'root',
'password' => 'root',
'driver_options' => [
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\'',
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
]
],
'service_manager' => array(
'factories' => array(
'Zend\Db\Adapter\Adapter' => function ($serviceManager) {
$adapterFactory = new Zend\Db\Adapter\AdapterServiceFactory();
$adapter = $adapterFactory->createService($serviceManager);
\Zend\Db\TableGateway\Feature\GlobalAdapterFeature::setStaticAdapter($adapter);
return $adapter;
}
),
),
);
Here my query:
try {
$db = $this->getServiceLocator()->get('Zend\Db\Adapter\Adapter');
$sql = "SELECT * FROM `table`";
$statement = $db->query($sql);
$res = $statement->execute();
} catch (PDOException $e) {
echo $e->getMessage();
}

Reivaldo, welcome to stackoverflow!
Since Zend DB drivers utilizing custom statement instances, Exceptions thrown by PDO and other possible errors handled internally and converting to Zend\Db\Adapter\Exception instances if necessary.
Check out this example.
Instead of catching the PDOException in your code, always catch possible exceptions from most specific one to most generic one. This is a good practice.
For example:
try {
// code to throw exceptions
} catch (\Zend\Db\Adapter\Exception $e) {
echo $e->getMessage();
} catch (\Exception $e) {
// This is not an adapter exception, anyway its an exception.
echo $e->getMessage();
} finally {
// This block always executed, an exception thrown or not.
}
You may also want to read some documentation about exception handling.
