Install Oracle client in your machine: http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html
Install/enable Oracle for PHP. That will depend on your operation system. In windows, I believe you only need to enable on your php.ini, extension=pdo_oci.dll. In linux, you need to install, with apt get or similar in your distro, or recompile PHP with instructions on this page: http://php.net/manual/en/ref.pdo-oci.php
Use this library in your Laravel project: https://github.com/yajra/laravel-oci8
In config/database.php:
'default' => env('DB_CONNECTION', 'my_connection'),
'connections' => [
'my_connection' => [
'driver' => 'oracle',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '1521'),
'service_name' => env('DB_SERVICE_NAME', ''),
'database' => env('DB_DATABASE', ''),
'username' => env('DB_USERNAME', ''),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'prefix' => '',
'options' => [
PDO::ATTR_PERSISTENT => true
],
],
In your .env:
DB_CONNECTION=my_connection
DB_HOST=111.111.111.111
DB_SERVICE_NAME=service
DB_DATABASE=db
DB_USERNAME=user
DB_PASSWORD=pass
