Laravel: Error [PDOException]: Could not Find Driver in MySQL

问题

I'm trying save a register in my MySQL database using Eloquent of Laravel 5

I edited database information in .env file, localized in my system root path, and in config/database.php maintain 'default' => 'mysql' and other mysql connection information (it using env('DB_DATABASE', 'forge') for get informations)

I can use Migration, but when I trying save register using function save() of my Model:

$newClient = new Client;
$newClient->name = "John";
$newClient->save();

It will occur the fallowing error:

PDOException in Connector.php line 47:
could not find driver

================================================================ For @user3158900:

I think my PHP has MySQL extension installed, fallowing my phpinfo() about Mysql
