Dokku deployed Silex can't find PdoServiceProvider - php

Question

I have a project done with Silex, and I was using herrera-io/silex-pdo as the PDO provider, but I faced random crashes with socket errors (I connect to the DB via socket), since that lib is abandoned, I changed to csanquer/pdo-service-provider, and it works just fine on my localhost server, but when I deploy to remote, I get the following error:
PHP Fatal error: Class 'Csanquer\Silex\PdoServiceProvider\Provider\PdoServiceProvider' not found in /app/web/index.php on line 52
Here is the code around the line 52:
use Csanquer\Silex\PdoServiceProvider\Provider\PdoServiceProvider;
$app->register(
// you can customize services and options prefix with the provider first argument (default = 'pdo')
new PdoServiceProvider('pdo'), // Line 52
array(
'pdo.server' => array(
// PDO driver to use among : mysql, pgsql , oracle, mssql, sqlite, dblib
'driver' => 'mysql',
'host' => 'unix_socket=/app/mysqld.sock',
'dbname' => 'db_beta',
'port' => 3306,
'user' => 'user',
'password' => 'pass',
),
// optional PDO attributes used in PDO constructor 4th argument driver_options
// some PDO attributes can be used only as PDO driver_options
// see http://www.php.net/manual/fr/pdo.construct.php
'pdo.options' => array(
\PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES 'UTF8'"
),
// optional PDO attributes set with PDO::setAttribute
// see http://www.php.net/manual/fr/pdo.setattribute.php
'pdo.attributes' => array(
\PDO::ATTR_ERRMODE => \PDO::ERRMODE_EXCEPTION,
),
)
);
Thanks in advance for any help, or any clue of what may be going wrong!

Answer 1

Turns out the problem was with the use instructions. To fix, simply change:
use Csanquer\Silex\PdoServiceProvider\Provider\PdoServiceProvider;
To:
use Csanquer\Silex\PdoServiceProvider\Provider\PDOServiceProvider;
And:
new PdoServiceProvider('pdo') To: new PDOServiceProvider('pdo')
Now it works!
